Located
in the heart of Tokyo, A-House was designed for a couple with two children, and
is sited in a high density, rapidly gentrifying neighbourhood characterised by
low-rise residential houses and narrow streets nearby a large park. The house
occupies a corner lot with south and west facing facades, and takes full
advantage of the minimal local regulations on volume design, allowing for unique
and site-specific house to be realised. The concrete structure is wrapped in a
façade composed of relief glass with a natural white printed pattern, giving
the house a monolithic appearance.
The volume, divided into four levels of
horizontally divided spaces with floor slabs of varying heights, is connected
by a small vertically screwed staircase that, given the small footprint of the
building, allows the greatest range of loft like spaces throughout the house. Two
bedrooms and a bathroom are situated on the lower level, a kitchen and dining
area on the ground floor, living and study on the first floor and a master bed
and bath on the top floor with an adjacent outdoor patio on the front end of
the house. This patio is strategically situated on the south side to allow for
the best natural daylight, while still being protected from the city beyond by
the glass façade, which envelopes the outdoor space.
The custom pattern printed glass façade
allows diffused natural light into the house, while the large openings allow
for further control of light filtration. The shutters of glass can be slid
back, allowing for maximum daylight and an open view. These sliding elements
offer privacy, but also serve as a mediation between the outside and inside,
for physical and visual connection. The basement level is offered natural light
by windows, at the base of the façade, at ground level, and is composed of the
same material as the façade, which gives uniformity to the structure.
The crystallised volume extends beyond the
neighbouring buildings on the southern portion of the site to allow a view of
the nearby park from the top floors, giving the house a connection to green
space, while still being set inside Tokyo’s sea of dense residential housing.
