2. The RIBA carried out a research project on this
matter of ‘space’. Using information submitted
for planning applications, the interior floor areas
have been examined across England's
8 major housebuilders,
compared to the non mandatory space standards
originating from The Local Authority for Greater
London (now nationwide).
“The average one bedroom home from our sample of 1,159 homes across 41
sites
is 46 sqm. It is 4 sqm short of the recommended
minimum for a single storey, one bedroom home for two residents.”
The Parker Morris Standards, named after the chair of the committee that drafted the report named “Homes for
today and tomorrow” as the first minimum standard requirements related to housing in 1961. It is often still
quoted today.
“It is better to build flats that are too large rather than too small”
"Additional space is an important long-term investment, for if a house or flat is large enough it can
usually be brought up-to-date as it gets older, but if there is not enough space improvements can be
impossible, or at least unduly expensive.“
The Parker Morris standards were made redundant by the conservative government in the 1980s.
What’s the Problem?

3. Setting a Precedent
‘Architects must take more responsibility for the design of projects and their direction with space
allocation’ - Assessing Lifetime Homes Standards and Part M Building Regulations for housing design in the UK
As part of the Sutton Three mixed use development, the core principles lay within creating resilient adaptable homes for
everyone
Homes, not housing because homes are for people
The Joseph Rowntree Foundation’s development in York aims
to establish a precedent of a social and environmentally
sustainable community ‘fit for the 21st century’.
Upon a residential survey there was positive satisfaction of
the design specifically related to the focus on standard of
space allocation, high ceilings, light from large windows
and potential for adaptability pre designed in to the
property one example being each dwelling having a cut roof
instead of trusses to allow for extending in to the loft space
when needed.
The National House Building Council (NHBC) published the
report ‘Futurology: the new homes in 2050’ recommending
various provisions for adaptability in new
housing creating a better future that is inclusive throughout a
buildings lifetime, with direct reference to Parker Morris “The
discussion about how and whether standards should be set
goes back to well before the Parker Morris report, Homes for
Today and Tomorrow in 1961, but an approach was established
then that will be as relevant in 2050 as it was in 1961.”
exclaiming the understanding that change must be realised.
Urban splash have provided housing with a difference with
‘house’, a modular timber frame construction that puts
peopleat the heart of decision making including
complete layout options for every floor, accommodated with
higher ceilings heights than the norm and larger windows that
would otherwise be typical for a multiple plot estate.

Key features
The project endeavours to be
accessible, adaptable and communal.
A place where people feel welcome
and belong. The primary users of the
residents and employees are
encouraged to intermingle at the
community hub, with all seating
orientated to accommodate
interaction with one another,
reflecting the biodiversity of wildlife
that are attracted to the dense
planters populated with wild shrubs
and flowers. The secondary users will
filter through as visitors to the
homes, food outlets and workplaces.
Parking is limited to one disabled
space per property with cycling
encouraged. Green space is an
important factor that will induce
greater wellbeing of all users. The
development is created to be living
through wildlife of land and sea, co-
populated with people.

Sugar Three focuses on people and
how they live and the space they
need
Accessibility for everybody is the driving
design concept
The 29m2 living room takes full advantage of the views and light
offered by the southern elevation
The high ceilings keep the rooms feeling spacious
A space to live and work, playful and practical
There is freedom to change
And adapt to all the needs of
the people that live in the
home
