The W building faces a side street that is busy area in Tokyo. The narrow site is surrounded by apartment buildings and office blocks.
To us it seemed quite similar to the bottom of a well.
To maintain a comfortable living environment in such uncomfortable surroundings, we built the maximum volume allowed on the site and cut a large opening at the top of the volume.
We maintained the maximum floor area, but manipulated voids on each level to create a method of bringing the sunlight from the top of the building to the bottom.
In accordance with Japanese building codes, the maximum volume is embodied.
