This project is a case study for
affordable small-size houses in the
densely built suburbs of Tokyo.
Despite statistics indicating that
Tokyo’s population will peak in 2015,
and thus potentially trigger an
unheard-of availability of inexpensive
central residential space, the suburban
sprawl continues. With land prices
high, any plot affordable for the
average family is far from big, their
110-140m2 low-cost houses almost
always occupying the maximum
buildable area. The density in these
developments is becoming so
unforgiving that what are supposed to
be gardens surrounding the houses are
mere leftovers featuring all the
building’s unfiltered machinery junk.
And yet, a detached house remains the
perennial dream. (While still rather
'free-standing' now, the construction of
immediate neighbours is likely to
happen within the next year.)
Putting aside the larger question
whether building in this low-rise landabsorbing
fashion is desirable,
strategies for a prototypical approach
must focus on solving the dichotomy of
maximising outside space whilst being
surrounded by a display of the
neighbouring buildings’ clutter. This
first case study proposes housing that
maximises its perimeter and opens up
towards the inside. Two U-shaped
volumes are stacked on top of each
other and joined to create fluid spaces
of living around a central garden. Yet
instead of closing off this inner garden,
alternating the orientation of the
volumes allows for air to flow through
and naturally ventilate the building,
drastically reducing cooling load
during the area's notoriously hot
summers. The interior space flows
continuously around this atrium on
ambiguous levels, internal heights vary
and thereby increase the perceived size
of the house.
When eventually the still remaining
gaps, which are but mere artefacts from
building regulations stipulating
setbacks, are conquered, the midterm
development might be a move from
detached house to housing
environments.
