House
in Okusawa
Situated within the quiet neighborhood of Okusawa in Tokyo, the house is
adjoined by residents from the three sides and the street in front. The
challenge was to accommodate patio spaces, as client requested from the
beginning of the project, within the rather elongated small residential
lot. In addition, the houses on both sides were still under construction
during our design process, thus the location of the outdoor spaces as well
as its relationship with the interior spaces became quite crucial. After
carefully experimenting with several schemes, we decided to place two patios,
both of which are 2.7m by 4.2m in their dimensions -- one near the adjacent
street on the south side and the other on the back of the house on the north.
Furthermore, some rooms were allocated to the semi-basement floor underneath
them to minimize the building volume.
The patios serve various functions since most of the rooms were placed along
them. Surrounded by exterior walls, these cavities fully and partially shield
the views from the surroundings, allowing for relatively larger openings
in the house. On the other hand, they act as apparatus not only to bring
the daylight into the interior but also, with the wall being the same color
as the rooms, to amplify the perceived interior space. While the north patio
surrounded by the entrance/stair-hall and the bathroom provides more private
space, the south patio near the street mediates between the outside and
inside of the house, being a semi-public space which visually draws a bit
of surrounding contexts into the interior spaces. In addition, although
the fac,ade adjacent to the street has no openings, the glimpse of the patio
from the street makes it less oppressive. Applying appropriate wall heights
for the patio and upper volumes resulted in fragmenting the fac,ade and
reducing the overall volume, further fitting the house to the scale of the
neighborhood.
The house is structured with exposed reinforced concrete for the half-basement
portion and wood framings for the rest. The half-basement floor elevates
the 1st floor level 1m above the entrance and consequently all the floors
become split-leveled. All the interior space, thus, is perceptibly weaved
together via entrance/stair hall and creates a spacious open space encompassing
the patios. The stark contrast of black and white used in the walls clearly
defines the house’s inner and outer appearances, further articulating the
overall design.
