‘11Boxes’ in Tokyo / Japan by Keiji Ashizawa Design

 The Japanese architect and designer realised this single family house in Tokyo / Japan which is based on a smart and simple construction method.

Here is what the architect explains:

“11 steel frame boxes are formed using steel angles and used as the main structure while external wall panels are attached on without the need of any additional structure. The size of the steel boxes needed to be considered carefully as it has to fit on a truck to be transported to site. These boxes are then joined together with high tension bolts on site. Though the central span holds the main structural strength of the building, the circulation stair is intentionally positioned there to operate as an earthquake-proof element as well as to rationalize the plan of the house. Span of the stair is 1.75m, wet area is 2.2m, bedrooms and living area are 2.55m and a varied unit is made fully utilize the limited depth available on site.”
