This single-family house is located on a site in a commercial area near a
main road in Tokyo.
Height restriction of the area is not strict therefore it is surrounded by
buildings with various heights. The site is sandwiched between old two-
storey house and five-storey apartment building. Our client requested us to
design an ‘open’ house in this densely populated environment.
In order to avoid unnecessary exposure to public view, we interpret this site
condition as a sort of ‘natural’ condition specific to the site. Standing on the
empty lot and carefully observing ‘open’ spots around it, we begin to
naturally envision the best location for courtyard and roof terrace, which are
two important elements requested by the client. Bedrooms are located on
the first floor, Living/Dining/Kitchen space on the second floor and loft space
above kitchen. Locations of all openings are carefully worked out in section,
so that they can open up towards the ‘open’ spots. Heights and locations of
walls around courtyard and roof terrace are designed according to various
specific factors of the site. In view of exterior factor we considered location of
windows of surrounding buildings, location of the roof, and height from the
ground. And in view of interior factors we considered view from inside,
natural light, roof, ceiling inclination. We make sure that openings are
placed at appropriate height and location so that they can open up the house
towards outside while keeping privacy. Space and form of the house are
decided in accordance with the client’s requests and the surrounding
‘nature’, without any arbitrary reasons. Walls are colored in black and
white; basically exterior walls are painted black and interior walls white.
And in some areas white interior walls extend outwards and meet black
exterior walls, and in some areas white interior volumes are made visible
from outside.
