Presentation is an attempt to define scope, meaning, strength and weakness of the two typologies f housinh

1. Plotted Development
Vs
Flatted Development

2. 1 Pattern of Development
 PD- Involves development based on and comprising of
generally large number of plots having variable sizes -- of
smaller size
 FD- Involves development based on few plots of larger size -
-as compared to plotted development
2 Pattern of Land Ownership
 PD- Land generally owned individually or jointly in the name
of few family members --to promote individual housing
 FD- Land held in joint ownership with large numbers of
owners-- to promote group housing
 3 Pattern of development- Height
 PD-Low rise going generally up to 3 stories high,
 FD- High rise-- generally going 4 or more stories.
5 Land Utilisation
 PD- Low with larger area going under roads and opens spaces
 FD- Higher order of land utlisation-- with smaller area going
under roads, and opens spaces

3. 5 Population/Housing Density
 PD—Low density-- due to individual ownership,--depending upon individual capacity,
resources or willingness to construct entire /part of building
 FD- Higher density--due to joint ownership ; depending upon combined resources
and combined effort to provide dwelling to all members/ landowners
6 Open Spaces
 PD- Small in size - Open spaces available within plots and held in private ownership
with limited use only by the owners- Increases need for making provision of large
open spaces at the Neighbourhood level
FD- Large in area- available as integral part of housing-- held in joint ownership to be
used by all the residents--. Reduces need for making provision of large open
spaces at the Neighbourhood level
7 Cost of Construction
 PD- Generally high --as in the case of low rise buildings and individual services
 FD- Generally low-- due to high rise and repetitive design of dwelling units and
common services
8 Social Sustainability
 PD- Low social sustainability-- due to limited social interaction –promoted by
individual living
 FD- High social sustainability --due to higher social interaction based on community
living

4. 9. Safety and Security
 PD- Low level of safety and security --due to individual living
 FD- High degree of safety and security --due to community living
10 Pattern of Living
 PD- Promotes individual living --leading to anonymity and exclusion
 FD- Promotes community living --leading to higher social interaction
11 Design of Unit
 PD- More design flexibility-- Large variations found in design --due to
individual ownership
FD- Low design flexibility --due to multiple units and joint ownership ---
leading to repetitive nature of design of dwelling units -– Uniformity of
design is the crux
 12 Cost of Maintenance of Services
 PD- Higher cost --due to individual maintenance. Expensive --considering
life-cycle cost of building.
 FD- Low maintenance cost- due to collective maintenance by society
created by the flat owners / fixed charges paid by each flat owner. Cost-
effective considering life –cycle cost

5. 13. Creation of Housing Stock
 PD- Low- due to non-construction on plot in one go - lower land utilisation
 FD- High- due to construction of all flats in one go --higher level of land
utilisation
14 Affordable Housing
 PD- Makes cost of housing high and unaffordable-- due to land cost and cost of
construction. Inefficient method to create large affordable housing stock
 FD- Makes housing cost-effective and affordable --due to shared land cost and
lower cost of construction, best method to create large housing stock
15 Sustainability
 PD- Low sustainability-due to large dependence on common facilities and services
provided in Neighbourhood
 FD- High sustainability- due to provision of common facilities and basic services
as part of group housing
16 Technologies
 PD- Offers limited options --for using state of art construction technologies and
minimising cost
 FD- Offers large options -- for using state of art construction technologies to
promote cost and material efficiency

6. 17. Green & Energy Efficient Buildings
 PD- Offers limited cost-effective options for-- promoting energy
efficiency, rain water harvesting , ground water recharging and solid waste
management.
 FD- Offers Large cost-effective options for -- promoting energy efficiency,
rain water harvesting , ground water recharging and solid waste
management
18 Ground Coverage
 PD- Ground coverage generally higher in case of smaller plots—
 -- However ground coverage /FAR becoming lower with increase in plot
area.
 FD- Ground coverage generally low as compared to plotted
development.–
 -- FAR in some cases changes with the width of approach road—
 -- Ground coverage and FAR normally donot change even with
increase/decrease in plot area.
 --Density achieved are always higher -- depending upon size of dwelling

7. 19 Parking Norms
 PD- No Parking norms defined for-- plotted
development, irrespective of plot size
 FD- Parking norms always defined-- for flatted
development, depending on the size and
category/number of dwelling units
20- Affordability
PD– Makes housing largely unaffordable
FD– Promotes high degree of affordability



8. 21. Housing Shortage
PD- Inefficient method of overcoming housing shortage
FD– Best option to increase housing supply and overcome the
housing shortage
22 Privacy
PD– Offers high degree of privacy due to individual living
FD– Less privacy due to community / joint living
23 Maintenance
PD– Problems of maintenance/upkeep can be attended
immediately
FD- Common problems of maintenance/upkeep are generally
ignored/ neglected/ delayed
24. Conflicts
PD- Social conflicts are limited
FD– large probability of social conflicts

9. 25 Management
PD-Individual/ family based management
FD- Community/society based management
