The
house is located in a quiet residential area in Tokyo. The street is quite
active and there are public facilities and greenery on the opposing side
The
more it goes upper level on this site, the more excellent the environment
becomes.

Our
main focus on the planning was to have the maximum space possible on the upper
level while not exceeding the floor-area ratio. In order to accomplish this,
the areas of the bottom levels were reduced.

Each floor resembles a “tray”, thus the overall image of the site
is that of trays stacked on top of each other being supported by steel columns
in-between.
Earthquake
resistance is accomplished by installing iron plate braces in the back of the
spandrel wall of each floor and built-in furniture. (Such as in the kitchen)

Because
the necessity for earthquake resistance is reduced on the upper floor, the
height of each level’s spandrel wall varies for privacy from the street.

The
site was 1.4 meters above the street therefore a basement level was
incorporated into the design. The functions are divided horizontally; parking,
entrance, and storage on the basement floor (street level); private rooms and
bathroom on the first floor; living room, dining room, and kitchen on the
second floor.

Each floor uses different interior fixtures so that they have a
unique character.
The
images of various sized and shaped trays layered upon one another help
the
view and privacy on each level.
