Introduction to the Report
This project will be assessing the current implications, success and potential of the Grandpont site, located west of Oxford City Centre. The report
will employ and seek to analyse the already created [Original] Grandpont Scheme, developed for Hand-in 1, 2 & 3.
The Original Grandpont Scheme used aerial imagery, SWOT analysis, traffic analysis, land use and morphological layers to create and a valid final
opinion and argument for the implications of Grandpont as a site, both within itself and the surrounding area. The Original Scheme researched and
assessed the success and failures of relevant case studies which could relate to the site of Grandpont. From this, a final design concept followed, in-
cluding final design actions to directly address concerns and points raised from the site analysis.
This Amended Scheme will seek to analyse and correct the Original Scheme by the employment of skills taught throughout the semester, including:
- Responsive Environments
- Morphological Layers
- Townscape
- Imageability.
Which will be combined in order to assess which factors improves and disproves a potential site, likewise to Grandpont.
Consequently, a revised design evolution will be completed in order to create a Final Grandpont Scheme, which will be analysed and cross-referenced
to the above skills and the Original Grandpont Scheme.

Introduction to the Site
Grandpont is a site within Oxford, England, located to the South-West of
the City Centre. The site is south of the existing Oxford Train Station and
lays parrallel to trains travelling in- and outbound into Oxford. The River
Thames runs around the north of the site, causing the site to be isolated
from the City Centre and likewise producing a lack of access points onto
the site. The existing access points consist of a footbridge to the north of
the site and a bridge for motor vehicles located a large distance east of the
site. The site was previously used for gas works up until the 1970s until the
area has since become stripped and left as a Nature Reserve for the use of
the public.
1) As seen by the map above, it can now be highlighted how close the
train track is to the site, measuring a decibel reading of: 94dB when
the reading is taken around 7 metres from the track, whilst the readings
measured 75dB in the eastern open field, Therefore, land use for the site,
must be considered.
2) Directly parrellel to the site, houses developed in the late 1960s are
present, whereby the nature is very council-developed style, with at-
tempted open areas for community use, such as ball games.
3) To the south of the site, a large open field for recreational uses are lo-
cated. This includes dog walking and use for children. This factor must
be strongly considered for Grandpont. However, placing houses close to
the dark, open areas would in turn increase the nature surveillance of the
area.
4) Located close to the site are expensive houses that have recently un-
dergone gentrification work to, in turn, increase the value of properties.
1) The Grandpont site is located south of Oxford City Centre, being ap-
proximately 0.8 miles away from the train station. There is a strong oppor-
tunity to redevelop the train station.
2) There are vast quantities of open space and the site is not designated as
Town Green however the land on the site ahs been contaminated.
3) To the north of the site, Jericho and Summertown are located. Both of
these disticts within Oxford are high end communities where houses are
both aesthetically pleasing and expensive. Therefore Grandpont, will need
to deliver the aesthetic reputation and match, if not increase the communit
strength.
4) The river acts as an excellent opportunity for the Grandpont site. It pass-
es around the border of the site.

Key Points Raised
This sheet shows the key points raised from the Initial Design Scheme and Proposals
1) Access Points and Roads
Access into the site is near impossible for a car. Vehicles must travel East
of the site, then drive southbound before heading back around to the West
in order to reach the site. A very prominent weakness and barrier. Howev-
er, as seen in the map above. there are 7 access points for pedestrians and
non-motor vehicles, which could be used to my advantage.
Fig 7: Access Roads on the site of Grandpont. Souce: Author
2) Infrastructure
The shaded areas are commercial/non-residential uses such as the train-
line whilst the outlined blocks are residential housing estates and devel-
opments. On the site, it is evident to see how Grandpont is on the edge of
development, whereby onwards from the site, development is non-existent
and the greenbelt starts.

3) Desire Paths / Roads
The map above shows the existing roads (black) and the calculated desire
paths created from use of pedestrians. From this analysis, it is evident that
the desire paths are very different from the existing roads created for the
use of the public. They also state how points/features of interest cause peo-
ple to leave the main track in order to investigate
Fig 9: Desire paths (red) and roads (black) on the site. Source Author
4) Blue Networks and Flooding
As seen above in the two corresponding maps, flooding and existing water
is a key issue. The presence of flooding on the site may be minimum, but its
the concern with the surrounding area. In reference to the map on the left,
it is evident that flooding stretches across many of the surrounding lands.
This makes access onto the site, as well as safety for children, a major
concern.
Fig 10: Risks of flooding on the site.
Maps.environment-agency.gov.uk
5) Green Networks
Green networks existing on the site currently are the strongest attribute.
Green networks are evident on the site and around the site, which increases
the feel of the area and acts as a rural retreat away from the city a near 0.5
miles away. Therefore, it must be stated that green networks upon the site
must be kept.

Responsive Environments
Responsive Environments is the “ideas that the built environment should
provide its users a democratic setting, maximising the degree of choice
available to them. This suggests that a responsive place is one in which
is flexible to the surrounding streets and sites, as well as offer permeable
spaces for users to use. From this, we can see that the Preliminary Design
Scheme consists of:
- Permeability: This scheme in fact offers many different ways through the
site, whereby the user can navigate through the site if one pleases or can
travel around the site via the northern route which connects the north-west
corner to the east of the site without any interaction with the site. There is
minimal segregation of buildings as the buildings are located on the routes.
Access into the blocks are strong as access points surround the perimeter
blocks. However, one thing that could be acknowledged is the largeness of
the blocks, making the users having to navigate around the buildings within
the site.
The sheets below shows a further, visual analysis of the design.
Morphology
Morphology states how measurements and character can determine the
success and viability of a site. In this scheme, we can see:
- There is arguably many active edges, however it must be considered which
areas realistically will be subject to larger amounts of footfall. Therefore,
the revised scheme should allow for allocations of designated inactive edg-
es.
- The traffic nature is difficult to determine due to the nature of the carless
community, yet from external research, it can be suggested cars and pe-
destrians should not be seperated, incorporating the possibility of shared
space.
The sheets below shows a further, visual analysis of the design.
Townscape
Townscape is the analysis of streets, spaces and areas through the concept
of serial vision, proposed by Gordon Cullen, which states how each area
or section of a site interacts with its surroundings the subsequent section.
It is the strength of interactions within a site. From the previous analysis
(see Hi5), the strongest features that should be included in the revised
scheme include:
- Netting and truncation, taking advantage of the Oxford scenes to the
distance whilst encapturing the strength within the site.
- Closed Vistas, lowering the building details and details in order for a far
more vital street.
- Pinpointing / focal points need to be included as the success of the City
Centre is due to destinction of the ‘dreaming spires’
- Encloses need to be incorporated as they offer many advantages to spac-
es.
The sheets below shows a further, visual analysis of the design.
Imageability
Imageability is the analysis of the legibility of a site, as seen in Hi6 with
the relevant analysis of Oxford City Centre by using Kevin Lynch’s con-
cepts.
- The paths / routes within the site are understandable and legible, how-
ever there is no defined beginning, middle and end to the routes as each
said route is short. This allows permeability but a lack of legibility and
character for users. Arguably, there are too many choices in navigation,
as each route leads to unnecessary and undesired locations.
The sheets below shows a further, visual analysis of the design.

- Variety: The variety on the site cannot be visualised from this scheme,
but DA2 states the buildings located to the west of the site, neighbouring
the trainline will be commercial / office developments. The below report
should analyse the implications and success rates of shops and commer-
cial use buildings below residential developments to allow for variable
street networks and uses.
- Robustness: This site does not offer many different opportunities for
different purposes, as the buildings are currently allocated as primarily
residential with minimal variety or open space.
- Legibility: The nature of the carless streets suggest that the users will
struggle to comprehend the routes as the car and pedestrian access points
are completely seperate. This must be researched and amended in the
report below.
- The blocks are very large, with small streets between each block, suggest-
ing how many of the roads are very well connected. This is due to the grid
nature, as is evident and successful within American cities.
- The traffic nature is difficult to determine due to the nature of the carless
community, yet from external research, it can be suggested cars and pe-
destrians should not be seperated, incorporating the possibility of shared
space.
- The dimensions must be reduced in order to allow for a clarification from
private and public space.
- There is arguably many active edges, however it must be considered which
areas realistically will be subject to larger amounts of footfall. Therefore,
the revised scheme should allow for allocations of designated inactive edg-
es.
- Due to the buildings being that of a perimeter block nature, it can be
suggested that the fronts and backs are a strong attribute within this site. A
perimeter block nature should be kept for the revised scheme.
- The dimensions must be reduced in order to allow for a clarification from
private and public space.

Above shows the factors that currently exist on the Grandpont scheme, of which include:
- Deflection: As seen in the blue, deflection has been exhibited on many of the road corners due to the 45
degree angle. This will entice users to explore and increase the safety one feels, something that must be kept
for the revised scheme.
- Block housing is following on from perimeter blocks, therefore having two advantages within the site. How-
ever, the perimeter block dimensions need to be increased and amended.
- Defined spaces often act as a landmark, suggesting that the amended scheme should use open spaces to its
advantage by enhancing them as opposed to creating another landmark.
- The nodes within the site are one of the strongest features. Being that of a carless communities, each node
exhibits much open space, offering enclosures and defined space to the user, as seen on the map. The defined
space should be kept for the revised scheme.
- Edges are prominent within this site, whereby the strongest feature evident is the river. The site is also sur-
rounded by a trainline and the small river to the south of the site. Within the site, there is minimal and must be
enhanced.
- Landmarks were seen as the strongest feature within Hi6, however the above original scheme shows no land-
marks. Hi6 stated how user would map the routes and legibility of a city based on the locations of landmarks,
suggesting how the revised scheme must include more landmarks to define the character of the site and increase
legibility.
- Districts are captured strongly within this scheme due to the seperation of residential and office sections.

Design Actions for Revised Scheme
Design Actions for Original Scheme
The above design actions are that which were implicated for the original
design scheme, accumulated and evident within Hand in 1 & 2.
There is a strong connection to responsive environments due to the impor-
tance of permeability and routes located as priority in the design evolution
of the site (see Hand In 1).
Therefore, the above design actions have been amended to include the ex-
plored criteria to achieve a more conservative and sound design scheme
which relates to far more criteria.
Design Actions for Revised Scheme
Therefore, the amended design actions that will be in place for the revised Grandpont scheme are seen above. The above design actions need to
be followed throughout the evolution of the site, whereby each action needs to be cross referenced to allow for a maximum possibility of design
soundness.
Each design action is written in reference to the factors that have arisen for imageability, responsive environments, morphology and townscape.
Design Objective
Considering the above, a final design objective has been created which must be followed throughout the evolution of the revised scheme:
The design objective for the revised Grandpont Scheme is to deliver a site which allows for many activities and places to stay, as opposed to
live. The site must be suitable for families and attend to the recent demographic shift of young single occupants, including that of students for
Oxford University.

Design Stage 1
Above shows the first stage of design, connecting all of
the existing access points onto the site together. Here we
see, likewise to the Original Scheme, how a small square
is naturally created, creating a defined space in response
to Townscape.
However, the street nature leaves minimal space for real-
istic buildings to be designed due to the sharp corners and
very small block sizes. Therefore, a much more general,
but still synced design stage must be carried forward.
Design Stage 2
Therefore, the roads have been generalised to form a
much more realistic and useable about of spaces.
This stage creates a Americanised grid-like street pattern
to the south of the site, leaving perfect block sizes for
perimeter blocks and rows of terraced houses, similar to
the surrounding area.
To the north of the site, the block sizes increase, suggest-
ing a potential for more mixed plots, such as housing and
flats. However, the block sizes are too large.
Design Stage 3
This design encapsulates the main points from the previ-
ous stages, including the grid nature to the south of the
site and the reduction in the block sizes.
The design shows green space parallel to the river in or-
der to preserve the currently present beauty of the site,
increasing the chance for planning permission and re-
ducing the chances of opposition.
However, the central block is too large in order to create
a successful and active perimeter block.
Design Stage 4
Considering the previous stages, a final design has
been produced which will be taken forward for the
final design.
To the west of the site, there is enough room for of-
fices and residential shared plots. To the north, more
affluent properties will be located due to the advan-
tage of the views across the river.
The large block from the previous stage has been re-
duced in order to create much more successful streets
and active edges.

Perimeter Blocks and Structure
Permeability is the concept that has been considered most highly within
the redesign of the project. The street network above was based around
the morphology and dimensions of the ideal perimeter block (100m x 80m
max.), addressing DA6, block size.
Retailers set their store locations on a 400m walking distance, hence the
retail has been located within the centre of the site. Due to the permeability
of the perimeter block, the walking distance is reduced, increases the legi-
bility for residents with and around the site.
Perimeter blocks, as evident within the amended design, offers fronts and
backs and a strong sense of natural surveillance.
Road Network
The road network has been considered highly from the previous scheme,
taking the concept of a carless community further. Within this design
scheme, roads have been allocated uses for different people, as seen in the
above image which seperates the cars from pedestrians working from the
left.
The blue symbolises shared space, allowing for controlled access for vehi-
cles, hence making the roads maneavable as well as still useable, for uses
such as emergency services. This concept addresses DA10, shared space
and DA4, mixed traffic nature. The roads have connected the north and
east, addressing DA18, improving the current lack of legibility present on
the site.
Active and Inactive Edges
The previous design offered minimal inactive edges throughout the site, a
positive that was attempted to be taken further. The above design shows
how the inactive edges have been mitigated by the use of edges, whereby
the inactive edges pose no concern by the lack of access to the user.
The use of perimeter blocks within the site allow for full, 360 degree sur-
veillance, reducing the impact of inactive edges, addressing DA3, active
and inactive edges.
Pedestrian path ways and access roads may suffer from inactive activity
within the night, hence the roads have been narrowed to increase natural
surveillance and safety on the site, addressing DA7, narrow roads.

Density
The site block nature and size has strongly considered DA5, which targets
a density of 100 people/ha, 40 dwellings/ha. As seen above, the map has
been divided into 100m² squares.
Each square exhibits different amounts of dwellings, suggesting mixed ten-
ure within the site, addressing DA17, mixed tenure. The density results in
an average of 38.8 dwellings/ha, very close to the target. Such a result leads
to a density of 93.2 people/ha (38.8*2.4), strong enough to support a good
bus service.
The density allows for a strong community to be developed, as well as
constantly surveyed streets by the activity present.
Fronts and Backs
The fronts and backs have been considered highly from the original design
scheme, removing the lack of clarification. The use of legible and defined
perimeter blocks forms a strong base which clarifies the fronts and backs.
Above shows how the amended design clarifies the fronts and backs, ad-
dressing DA2, fronts and backs. Sucessfully, the backs are out of access
to the typical user, allowing access to only the owning occupants of the
dwellings.
There is a lack of clarification of fronts however, due to the lack of front
gardens and the concept of Chimey Pot Park, which gives priority to vehi-
cles, as seen in the magnified image above.
Building Uses
Building uses have been located in order to create districts, a concept that
will be explored further in the below pages. The difference in building
uses addresses DA17, mixed tenure.
To the left of the site, as seen in red, offices have been located below af-
fordable flats. The employment of such a concept will mitigate the noise
and vibration of the adjacent train, addressing DA12, train noise.
The centre of the site (purple) exhibits retail activity which is located
below increased value rents. This addresses DA9, local amenities.
The surrounding areas are designated for houses, addressing DA17.

Street Breakdown and Character
The street and house character will be based off the surrounding area, be-
ing that of victorian, three-storey terraced housing, resulting in the houses
being adjoined and uniform in style, addressing DA8, similar styled hous-
ing. Below shows the street breakdown for the road located to the south
of the site, which will allow for mixed use, addressing DA4, mixed traffic
nature. The below street breakdown shows the safety for pedestrians from
the space as well as room for street parking.
Above shows the street breakdown of the road located to the centre of site,
which will be controlled access for vehicles, allowing priority for pedes-
trians. This concept addresses DA’s 4, 7 narrow pedestrian roads and 10,
shared space. The employment of said concept will allow for constant nat-
ural sureillance from the bordering houses and constant use by pedestrians

The above shows the dimensions of the blocks within the site.
The block, plots ands buildings have been designed in relation
to Norham Manor, which states the strengths of large block
design. Considering the above, each block has been designed
with garden space for every house, as well as shared commu-
nal spaces for flats. Previous analysis’(Morphology), states the
importance of open space for every resident.
The block dimensions use the measurements from DA6, block
size 100m x 80m, achieving this or below. Above the target
layer will decrease natural surveillance and safety within the
site.
The size of the houses have been considered as well, ranging
from 6m to 10m, employed within the south west estate.

Amended Design Scheme
Townscape Analysis
This sheet will analyse the new and amended design scheme in relation to the principles of Townscape
16
Enclosure
The yellow shows the enclosure within the site, being that of a communal
open space for the surrounding flats, in turn increasing community strength.
Deflection
Deflection is minimal within the site, being a weakness that has not been
fully utilised, yet pockets and examples are still evident, addressing DA21
Narrows
Narrows located within the site cause the user to understand more detail is
located through the pathway, as is exhibited above.
Truncation
Truncation states how designs, buildings and features are improved by dis-
tance and framing. This is seen above, suggesting an improvement to the
original design and addressing DA15, netting and truncation.
Punctuation
Punctuation states the break in roads cause the users to not become bored,
as seen minimally once in the pink above.
Focal Point
Focal points are not fully utilised but are still minimal. This further sug-
gests how the final design does not satisfy townscape fully.
Block House
The concept of block houses is curved, uniform causes residents and users
to be directed, as seen in the blue which utilises the 45 degree corners.
Defined Spaces
Spaces that are open and create public spaces can be seen as defined spaces
due to the viscosity they deliver, making users remember where to meet,
addressing DA16, defined spaces.
Hereness and Thereness
Hereness and thereness is minimal within the site, except the link between
the two defined space.

Amended Design Scheme
Imageability Analysis
This sheet will analyse the new and amended design scheme in relation to the principles of Imageability
17
Districts
Districts are highly considered within the amending of the Grandpont
scheme. As seen above, the site has been broken down into clear districts,
including office and retail sectors for a local economy, addressing DA19,
districts.
Districts are fully utilised by the use of mixed tenure, further addressing
DA17, mixed tenure. This is reached by the employment of flats located
above shop and offices. Such an implication causes the office district to
have constant natural surveillance and active edges, as opposed to 9 - 5 sur-
veillance which was evident within the previous, orginal scheme, further
addressing DA3, active and inactive edges.
Nodes
Nodes and junctions are clearly defined and evident within the site, with
one strong node for pedestrians and one strong node for vehicles, suggest-
ing a strong seperation between users heirarchy. Each node has many routes
spidering from the centre, suggesting large options of choice.
Edges
Edges are minimally employed within the site, sugggesting a lack of detail
within the new site which focuses primarily on the design and structure.
However, the site is surrounded by a very useful edge, including that of the
river and the trainline, which acts as a barrier to the users. This has been
used to the sites advantage, as it flows traffic in a fluid, consistent manner.
Routes
Routes within the site are legible, permeable and easy to use due to the
choice of access point and maneavability within the site. This suggests how
the site of Grandpont has improved from the previous design, as cars are
now allowed fully within the site as well as a simple and understandable
breakdown of road types, such as primary and secondary. This addresses
DA11, river to be ehanced, due to the route now bordering the rivers edge,
in turn gentrifying the existing walkway.
Landmarks
It is seen above how there are no landmarks which define the area as a
whole, but as seen above, defined open spaces could act as DA14.

Comparison and Conclusion
This sheet will analyse the new and amended design scheme in relation to the principles of Imageability
18
When comparing the evolution from the Original Scheme to the Amended
Scheme, one must consider the execution via the new skills developed,
including that of morphology, imagebility and townscape.
Below shows which Design Actions have been addressed (Green), and
which ones are present but could be further improved (Red)
DA1: Existing Access Points improved
DA2: Fronts and Backs defined
DA3: Active and Inactive Edges
DA4: Mixed Traffic Nature
DA5: Density Target: 100 people/ha, 40 dwellings/ha
DA6: Block size maximum: 100M x 80m
DA7: Narrow pedestrian roads
DA8: Housing similar character and nature to surrounding area
DA9: Local amenities within the site
DA10: Shared Space
DA11: River to be enhanced
DA12: Train noise and vibration to be reduced
DA13: Trees and open space to be employed within the site
DA14: At least one landmark to be employed within the site
DA15: Netting and truncation within the site
DA16: Defined Spaces
DA17: Mixed tenure throughout the site
DA18: Pathways connecting the existing North to the East
DA19: Districts to be clearly defined
DA20: Block size to be reduced from previous design
DA21: Deflection to be employed to increase safety
From the above, it can be seen that each design action is at least present,
suggesting a strong improvement from the original design. The original
design based much of its design from responsive environments, hence its
successful perimeter block which offer full natural surveillance. However,
as seen in the above analysis (page 5), the original design remained with
many concerns regarding morphology, imageability and townscape, such
as the narrow, unrealistic streets.
The amended design, seen right, addresses the problems arisen from such
an analysis to form design actions, consequently to lead onto design im-
plications within the final design. As seen in the 2nd above analysis, (page
13), the new design offers a stronger, final product which addresses the ke
concepts raised from the methodology.

Bibliography
This evolution process has enabled the skills that are needed within suc-
cessful and existing streets which are modelled within many new streets, to
be employed within a real world site.
A greater understanding has been developed regarding which concepts are
the strongest together and which elements, such as perimeter blocks, nodes
and districts add the greatest effect to such a project.
Conclusion
The above design analysis has resulted in a design concept for Grandpont
which is balanced, legible, varied and realistically reasonable, developed
from the understanding of morphology.
Fundamental improvements have been developed to enhance the quality of
the existing land with maximum possible opportunities for planning per-
mission due to the mixed tenure and concepts employed collectively. The
park is still present on the site, suggesting how any opposition from plan-
ning permission could be reduced. The design concept will improve the
surrounding area, due to the similar nature of the cracked window theory,
which states one window will cause the rest of the windows, increasing
exponetially. This concept could be applied for Grandpont, whilst the win-
dow symbolises the sites. The surrounding sites will inevitaly improve due
to the economic demand and regeneration pressure of inner city, brownfield
sites.
Thus, it can be stated the location, implication and design of the Amended
Grandpont Scheme improves the surrounding area as well as the site itself,
suggesting the success of said Scheme.

The report will employ and seek to analyse the already created [Original] Grandpont Scheme, developed for Hand-in 1, 2 & 3. The Original Grandpont Scheme used aerial imagery, SWOT analysis, traffic analysis, land use and morphological layers to create and a valid final opinion and argument for the implications of Grandpont as a site, both within itself and the surrounding area. The Original Scheme researched and assessed the success and failures of relevant case studies which could relate to the site of Grandpont. From this, a final design concept followed, in- cluding final design actions to directly address concerns and points raised from the site analysis. This Amended Scheme will seek to analyse and correct the Original Scheme by the employment of skills taught throughout the semester, including: - Responsive Environments - Morphological Layers - Townscape - Imageability. Which will be combined in order to assess which factors improves and disproves a potential site, likewise to Grandpont. Consequently, a revised design evolution will be completed in order to create a Final Grandpont Scheme, which will be analysed and cross-referenced to the above skills and the Original Grandpont Scheme.

  • 3. 3 Introduction to the Site Grandpont is a site within Oxford, England, located to the South-West of the City Centre. The site is south of the existing Oxford Train Station and lays parrallel to trains travelling in- and outbound into Oxford. The River Thames runs around the north of the site, causing the site to be isolated from the City Centre and likewise producing a lack of access points onto the site. The existing access points consist of a footbridge to the north of the site and a bridge for motor vehicles located a large distance east of the site. The site was previously used for gas works up until the 1970s until the area has since become stripped and left as a Nature Reserve for the use of the public. 1) As seen by the map above, it can now be highlighted how close the train track is to the site, measuring a decibel reading of: 94dB when the reading is taken around 7 metres from the track, whilst the readings measured 75dB in the eastern open field, Therefore, land use for the site, must be considered. 2) Directly parrellel to the site, houses developed in the late 1960s are present, whereby the nature is very council-developed style, with at- tempted open areas for community use, such as ball games. 3) To the south of the site, a large open field for recreational uses are lo- cated. This includes dog walking and use for children. This factor must be strongly considered for Grandpont. However, placing houses close to the dark, open areas would in turn increase the nature surveillance of the area. 4) Located close to the site are expensive houses that have recently un- dergone gentrification work to, in turn, increase the value of properties. 1) The Grandpont site is located south of Oxford City Centre, being ap- proximately 0.8 miles away from the train station. There is a strong oppor- tunity to redevelop the train station. 2) There are vast quantities of open space and the site is not designated as Town Green however the land on the site ahs been contaminated. 3) To the north of the site, Jericho and Summertown are located. Both of these disticts within Oxford are high end communities where houses are both aesthetically pleasing and expensive. Therefore Grandpont, will need to deliver the aesthetic reputation and match, if not increase the communit strength. 4) The river acts as an excellent opportunity for the Grandpont site. It pass- es around the border of the site. Fig 4: Entrance sign for Grandpont is not destinct and does not resemble a new area from the surrounding estate.

Vehicles must travel East of the site, then drive southbound before heading back around to the West in order to reach the site. A very prominent weakness and barrier. Howev- er, as seen in the map above. there are 7 access points for pedestrians and non-motor vehicles, which could be used to my advantage. Fig 7: Access Roads on the site of Grandpont. Souce: Author 2) Infrastructure The shaded areas are commercial/non-residential uses such as the train- line whilst the outlined blocks are residential housing estates and devel- opments. On the site, it is evident to see how Grandpont is on the edge of development, whereby onwards from the site, development is non-existent and the greenbelt starts. Fig 8: Surrounding infrastructure on the site (shaded). Source: Author 3) Desire Paths / Roads The map above shows the existing roads (black) and the calculated desire paths created from use of pedestrians. From this analysis, it is evident that the desire paths are very different from the existing roads created for the use of the public. They also state how points/features of interest cause peo- ple to leave the main track in order to investigate Fig 9: Desire paths (red) and roads (black) on the site. Source Author 4) Blue Networks and Flooding As seen above in the two corresponding maps, flooding and existing water is a key issue. The presence of flooding on the site may be minimum, but its the concern with the surrounding area. In reference to the map on the left, it is evident that flooding stretches across many of the surrounding lands. This makes access onto the site, as well as safety for children, a major concern. Fig 10: Risks of flooding on the site. Maps.environment-agency.gov.uk 5) Green Networks Green networks existing on the site currently are the strongest attribute. Green networks are evident on the site and around the site, which increases the feel of the area and acts as a rural retreat away from the city a near 0.5 miles away. Therefore, it must be stated that green networks upon the site must be kept. Fig 11:The green networks existing in and around the site. Source: AuthorFig 10: Blue networks present. Source: Author
  • 7. Preliminary Design Scheme Critical Evaluation 5 Responsive Environments Responsive Environments is the “ideas that the built environment should provide its users a democratic setting, maximising the degree of choice available to them. This suggests that a responsive place is one in which is flexible to the surrounding streets and sites, as well as offer permeable spaces for users to use. From this, we can see that the Preliminary Design Scheme consists of: - Permeability: This scheme in fact offers many different ways through the site, whereby the user can navigate through the site if one pleases or can travel around the site via the northern route which connects the north-west corner to the east of the site without any interaction with the site. There is minimal segregation of buildings as the buildings are located on the routes. Access into the blocks are strong as access points surround the perimeter blocks. However, one thing that could be acknowledged is the largeness of the blocks, making the users having to navigate around the buildings within the site. The sheets below shows a further, visual analysis of the design. Morphology Morphology states how measurements and character can determine the success and viability of a site. In this scheme, we can see: - There is arguably many active edges, however it must be considered which areas realistically will be subject to larger amounts of footfall. Therefore, the revised scheme should allow for allocations of designated inactive edg- es. - The traffic nature is difficult to determine due to the nature of the carless community, yet from external research, it can be suggested cars and pe- destrians should not be seperated, incorporating the possibility of shared space. The sheets below shows a further, visual analysis of the design. Townscape Townscape is the analysis of streets, spaces and areas through the concept of serial vision, proposed by Gordon Cullen, which states how each area or section of a site interacts with its surroundings the subsequent section. It is the strength of interactions within a site. From the previous analysis (see Hi5), the strongest features that should be included in the revised scheme include: - Netting and truncation, taking advantage of the Oxford scenes to the distance whilst encapturing the strength within the site. - Closed Vistas, lowering the building details and details in order for a far more vital street. - Pinpointing / focal points need to be included as the success of the City Centre is due to destinction of the ‘dreaming spires’ - Encloses need to be incorporated as they offer many advantages to spac- es. The sheets below shows a further, visual analysis of the design. Imageability Imageability is the analysis of the legibility of a site, as seen in Hi6 with the relevant analysis of Oxford City Centre by using Kevin Lynch’s con- cepts. - The paths / routes within the site are understandable and legible, how- ever there is no defined beginning, middle and end to the routes as each said route is short. This allows permeability but a lack of legibility and character for users. Arguably, there are too many choices in navigation, as each route leads to unnecessary and undesired locations. The sheets below shows a further, visual analysis of the design. Fig 12: Final, original Grandpont Scheme. Source: Author
  • 8. 6 - Variety: The variety on the site cannot be visualised from this scheme, but DA2 states the buildings located to the west of the site, neighbouring the trainline will be commercial / office developments. The below report should analyse the implications and success rates of shops and commer- cial use buildings below residential developments to allow for variable street networks and uses. - Robustness: This site does not offer many different opportunities for different purposes, as the buildings are currently allocated as primarily residential with minimal variety or open space. - Legibility: The nature of the carless streets suggest that the users will struggle to comprehend the routes as the car and pedestrian access points are completely seperate. This must be researched and amended in the report below. - The blocks are very large, with small streets between each block, suggest- ing how many of the roads are very well connected. This is due to the grid nature, as is evident and successful within American cities. - The traffic nature is difficult to determine due to the nature of the carless community, yet from external research, it can be suggested cars and pe- destrians should not be seperated, incorporating the possibility of shared space. - The dimensions must be reduced in order to allow for a clarification from private and public space. - There is arguably many active edges, however it must be considered which areas realistically will be subject to larger amounts of footfall. Therefore, the revised scheme should allow for allocations of designated inactive edg- es. - Due to the buildings being that of a perimeter block nature, it can be suggested that the fronts and backs are a strong attribute within this site. A perimeter block nature should be kept for the revised scheme. - The dimensions must be reduced in order to allow for a clarification from private and public space.

  • 9. 7 Above shows the factors that currently exist on the Grandpont scheme, of which include: - Deflection: As seen in the blue, deflection has been exhibited on many of the road corners due to the 45 degree angle. This will entice users to explore and increase the safety one feels, something that must be kept for the revised scheme. - Block housing is following on from perimeter blocks, therefore having two advantages within the site. How- ever, the perimeter block dimensions need to be increased and amended. - Defined spaces often act as a landmark, suggesting that the amended scheme should use open spaces to its advantage by enhancing them as opposed to creating another landmark. - The nodes within the site are one of the strongest features. Being that of a carless communities, each node exhibits much open space, offering enclosures and defined space to the user, as seen on the map. The defined space should be kept for the revised scheme. - Edges are prominent within this site, whereby the strongest feature evident is the river. The site is also sur- rounded by a trainline and the small river to the south of the site. Within the site, there is minimal and must be enhanced. - Landmarks were seen as the strongest feature within Hi6, however the above original scheme shows no land- marks. Hi6 stated how user would map the routes and legibility of a city based on the locations of landmarks, suggesting how the revised scheme must include more landmarks to define the character of the site and increase legibility. - Districts are captured strongly within this scheme due to the seperation of residential and office sections.

There is a strong connection to responsive environments due to the impor- tance of permeability and routes located as priority in the design evolution of the site (see Hand In 1). Therefore, the above design actions have been amended to include the ex- plored criteria to achieve a more conservative and sound design scheme which relates to far more criteria. Design Actions for Revised Scheme Therefore, the amended design actions that will be in place for the revised Grandpont scheme are seen above. The above design actions need to be followed throughout the evolution of the site, whereby each action needs to be cross referenced to allow for a maximum possibility of design soundness. Each design action is written in reference to the factors that have arisen for imageability, responsive environments, morphology and townscape. Design Objective Considering the above, a final design objective has been created which must be followed throughout the evolution of the revised scheme: The design objective for the revised Grandpont Scheme is to deliver a site which allows for many activities and places to stay, as opposed to live. The site must be suitable for families and attend to the recent demographic shift of young single occupants, including that of students for Oxford University.
  • 12. Amended Design Scheme Final Design Evolution This page shows the amended scheme block and road evolution, taking into consideration the abovementioned methods and design actions. The final image will be taken forward for the final design. 9 Design Stage 1 Above shows the first stage of design, connecting all of the existing access points onto the site together. Here we see, likewise to the Original Scheme, how a small square is naturally created, creating a defined space in response to Townscape. However, the street nature leaves minimal space for real- istic buildings to be designed due to the sharp corners and very small block sizes. Therefore, a much more general, but still synced design stage must be carried forward. Design Stage 2 Therefore, the roads have been generalised to form a much more realistic and useable about of spaces. This stage creates a Americanised grid-like street pattern to the south of the site, leaving perfect block sizes for perimeter blocks and rows of terraced houses, similar to the surrounding area. To the north of the site, the block sizes increase, suggest- ing a potential for more mixed plots, such as housing and flats. However, the block sizes are too large. Design Stage 3 This design encapsulates the main points from the previ- ous stages, including the grid nature to the south of the site and the reduction in the block sizes. The design shows green space parallel to the river in or- der to preserve the currently present beauty of the site, increasing the chance for planning permission and re- ducing the chances of opposition. However, the central block is too large in order to create a successful and active perimeter block. Design Stage 4 Considering the previous stages, a final design has been produced which will be taken forward for the final design. To the west of the site, there is enough room for of- fices and residential shared plots. To the north, more affluent properties will be located due to the advan- tage of the views across the river. The large block from the previous stage has been re- duced in order to create much more successful streets and active edges. Fig 18: Access points connected.

  • 17. Amended Design Scheme Responsive Environments Analysis This sheet will analyse the new and amended design scheme in relation to the principles of Responsive Environments 13 Perimeter Blocks and Structure Permeability is the concept that has been considered most highly within the redesign of the project. The street network above was based around the morphology and dimensions of the ideal perimeter block (100m x 80m max.), addressing DA6, block size. Retailers set their store locations on a 400m walking distance, hence the retail has been located within the centre of the site. Due to the permeability of the perimeter block, the walking distance is reduced, increases the legi- bility for residents with and around the site. Perimeter blocks, as evident within the amended design, offers fronts and backs and a strong sense of natural surveillance. Road Network The road network has been considered highly from the previous scheme, taking the concept of a carless community further. Within this design scheme, roads have been allocated uses for different people, as seen in the above image which seperates the cars from pedestrians working from the left. The blue symbolises shared space, allowing for controlled access for vehi- cles, hence making the roads maneavable as well as still useable, for uses such as emergency services. This concept addresses DA10, shared space and DA4, mixed traffic nature. The roads have connected the north and east, addressing DA18, improving the current lack of legibility present on the site. Active and Inactive Edges The previous design offered minimal inactive edges throughout the site, a positive that was attempted to be taken further. The above design shows how the inactive edges have been mitigated by the use of edges, whereby the inactive edges pose no concern by the lack of access to the user. The use of perimeter blocks within the site allow for full, 360 degree sur- veillance, reducing the impact of inactive edges, addressing DA3, active and inactive edges. Pedestrian path ways and access roads may suffer from inactive activity within the night, hence the roads have been narrowed to increase natural surveillance and safety on the site, addressing DA7, narrow roads. 0 100 N 0 100 N 0 100 N Fig 41: Perimeter Blocks.

  • 18. Amended Design Scheme Morphology Analysis This sheet will analyse the new and amended design scheme in relation to the principles of Morphology 14 Density The site block nature and size has strongly considered DA5, which targets a density of 100 people/ha, 40 dwellings/ha. As seen above, the map has been divided into 100m² squares. Each square exhibits different amounts of dwellings, suggesting mixed ten- ure within the site, addressing DA17, mixed tenure. The density results in an average of 38.8 dwellings/ha, very close to the target. Such a result leads to a density of 93.2 people/ha (38.8*2.4), strong enough to support a good bus service. The density allows for a strong community to be developed, as well as constantly surveyed streets by the activity present. Fronts and Backs The fronts and backs have been considered highly from the original design scheme, removing the lack of clarification. The use of legible and defined perimeter blocks forms a strong base which clarifies the fronts and backs. Above shows how the amended design clarifies the fronts and backs, ad- dressing DA2, fronts and backs. Sucessfully, the backs are out of access to the typical user, allowing access to only the owning occupants of the dwellings. There is a lack of clarification of fronts however, due to the lack of front gardens and the concept of Chimey Pot Park, which gives priority to vehi- cles, as seen in the magnified image above. Building Uses Building uses have been located in order to create districts, a concept that will be explored further in the below pages. The difference in building uses addresses DA17, mixed tenure. To the left of the site, as seen in red, offices have been located below af- fordable flats. The employment of such a concept will mitigate the noise and vibration of the adjacent train, addressing DA12, train noise. The centre of the site (purple) exhibits retail activity which is located below increased value rents. This addresses DA9, local amenities. The surrounding areas are designated for houses, addressing DA17. 41 25 37 52 34 44 0 100 N 0 100 N 0 100 N Fig 44. Density, 6 squares. Source: Author Fig 45. Fronts and Backs. Source: Author Fig 46.

Amended Design Scheme Morphology Analysis This sheet will analyse the new and amended design scheme in relation to the principles of Morphology 15 Street Breakdown and Character The street and house character will be based off the surrounding area, be- ing that of victorian, three-storey terraced housing, resulting in the houses being adjoined and uniform in style, addressing DA8, similar styled hous- ing. Below shows the street breakdown for the road located to the south of the site, which will allow for mixed use, addressing DA4, mixed traffic nature. The below street breakdown shows the safety for pedestrians from the space as well as room for street parking. Above shows the street breakdown of the road located to the centre of site, which will be controlled access for vehicles, allowing priority for pedes- trians. This concept addresses DA’s 4, 7 narrow pedestrian roads and 10, shared space. The employment of said concept will allow for constant nat- ural sureillance from the bordering houses and constant use by pedestrians and vehicles. 74.8m 37.1m 10.0m 16.5m 252.2m 69.9m 69.8m 99.3m 204m 75.2m 71.9m 14.2m 55.3m 82.7m 26.0m 8m 77.6m 67.2m 89.5m 63.7m 50.0m 106.3m 9.93m 33.7m 69.8m 48.4m 68.8m Dimensions 129m 418m 204m The above shows the dimensions of the blocks within the site. The block, plots ands buildings have been designed in relation to Norham Manor, which states the strengths of large block design. Considering the above, each block has been designed with garden space for every house, as well as shared commu- nal spaces for flats. Previous analysis’(Morphology), states the importance of open space for every resident. The block dimensions use the measurements from DA6, block size 100m x 80m, achieving this or below. Above the target layer will decrease natural surveillance and safety within the site. The size of the houses have been considered as well, ranging from 6m to 10m, employed within the south west estate. 0 100 N Fig 47. Dimension Breakdown of the site. Source: Author Fig 48.

Deflection Deflection is minimal within the site, being a weakness that has not been fully utilised, yet pockets and examples are still evident, addressing DA21 Narrows Narrows located within the site cause the user to understand more detail is located through the pathway, as is exhibited above. Truncation Truncation states how designs, buildings and features are improved by dis- tance and framing. This is seen above, suggesting an improvement to the original design and addressing DA15, netting and truncation. Punctuation Punctuation states the break in roads cause the users to not become bored, as seen minimally once in the pink above. Focal Point Focal points are not fully utilised but are still minimal. This further sug- gests how the final design does not satisfy townscape fully. Block House The concept of block houses is curved, uniform causes residents and users to be directed, as seen in the blue which utilises the 45 degree corners. Defined Spaces Spaces that are open and create public spaces can be seen as defined spaces due to the viscosity they deliver, making users remember where to meet, addressing DA16, defined spaces. Hereness and Thereness Hereness and thereness is minimal within the site, except the link between the two defined space. 0 100 N 0 100 N 0 100 N Fig 50. Enclosures, Deflection and Narrows.

  • 21. Amended Design Scheme Imageability Analysis This sheet will analyse the new and amended design scheme in relation to the principles of Imageability 17 Districts Districts are highly considered within the amending of the Grandpont scheme. As seen above, the site has been broken down into clear districts, including office and retail sectors for a local economy, addressing DA19, districts. Districts are fully utilised by the use of mixed tenure, further addressing DA17, mixed tenure. This is reached by the employment of flats located above shop and offices. Such an implication causes the office district to have constant natural surveillance and active edges, as opposed to 9 - 5 sur- veillance which was evident within the previous, orginal scheme, further addressing DA3, active and inactive edges. Nodes Nodes and junctions are clearly defined and evident within the site, with one strong node for pedestrians and one strong node for vehicles, suggest- ing a strong seperation between users heirarchy. Each node has many routes spidering from the centre, suggesting large options of choice. Edges Edges are minimally employed within the site, sugggesting a lack of detail within the new site which focuses primarily on the design and structure. However, the site is surrounded by a very useful edge, including that of the river and the trainline, which acts as a barrier to the users. This has been used to the sites advantage, as it flows traffic in a fluid, consistent manner. Routes Routes within the site are legible, permeable and easy to use due to the choice of access point and maneavability within the site. This suggests how the site of Grandpont has improved from the previous design, as cars are now allowed fully within the site as well as a simple and understandable breakdown of road types, such as primary and secondary. This addresses DA11, river to be ehanced, due to the route now bordering the rivers edge, in turn gentrifying the existing walkway. Landmarks It is seen above how there are no landmarks which define the area as a whole, but as seen above, defined open spaces could act as DA14. 0 100 N 0 100 N 0 100 N Fig 53.

  • 22. Comparison and Conclusion This sheet will analyse the new and amended design scheme in relation to the principles of Imageability 18 When comparing the evolution from the Original Scheme to the Amended Scheme, one must consider the execution via the new skills developed, including that of morphology, imagebility and townscape. Below shows which Design Actions have been addressed (Green), and which ones are present but could be further improved (Red) DA1: Existing Access Points improved DA2: Fronts and Backs defined DA3: Active and Inactive Edges DA4: Mixed Traffic Nature DA5: Density Target: 100 people/ha, 40 dwellings/ha DA6: Block size maximum: 100M x 80m DA7: Narrow pedestrian roads DA8: Housing similar character and nature to surrounding area DA9: Local amenities within the site DA10: Shared Space DA11: River to be enhanced DA12: Train noise and vibration to be reduced DA13: Trees and open space to be employed within the site DA14: At least one landmark to be employed within the site DA15: Netting and truncation within the site DA16: Defined Spaces DA17: Mixed tenure throughout the site DA18: Pathways connecting the existing North to the East DA19: Districts to be clearly defined DA20: Block size to be reduced from previous design DA21: Deflection to be employed to increase safety From the above, it can be seen that each design action is at least present, suggesting a strong improvement from the original design. The original design based much of its design from responsive environments, hence its successful perimeter block which offer full natural surveillance. However, as seen in the above analysis (page 5), the original design remained with many concerns regarding morphology, imageability and townscape, such as the narrow, unrealistic streets. The amended design, seen right, addresses the problems arisen from such an analysis to form design actions, consequently to lead onto design im- plications within the final design. As seen in the 2nd above analysis, (page 13), the new design offers a stronger, final product which addresses the ke concepts raised from the methodology. 0 100 N 0 100 N Fig 56.

Bibliography This evolution process has enabled the skills that are needed within suc- cessful and existing streets which are modelled within many new streets, to be employed within a real world site. A greater understanding has been developed regarding which concepts are the strongest together and which elements, such as perimeter blocks, nodes and districts add the greatest effect to such a project. Conclusion The above design analysis has resulted in a design concept for Grandpont which is balanced, legible, varied and realistically reasonable, developed from the understanding of morphology. Fundamental improvements have been developed to enhance the quality of the existing land with maximum possible opportunities for planning per- mission due to the mixed tenure and concepts employed collectively. The park is still present on the site, suggesting how any opposition from plan- ning permission could be reduced. The design concept will improve the surrounding area, due to the similar nature of the cracked window theory, which states one window will cause the rest of the windows, increasing exponetially. This concept could be applied for Grandpont, whilst the win- dow symbolises the sites. The surrounding sites will inevitaly improve due to the economic demand and regeneration pressure of inner city, brownfield sites. Thus, it can be stated the location, implication and design of the Amended Grandpont Scheme improves the surrounding area as well as the site itself, suggesting the success of said Scheme.
