Keiji Ashizawa Design is an architectural and product design studio based in Tokyo, Japan. Formed in 2005 by Keiji Ashizawa, following ten years working experience in both architecture and steel fabrication. In their work their focus on ‘honest’ design – simple yet refined, thoughtful and of a light manner. This is surely the house we would feel safer during some threatening earthquake.
"In order to maximize space on site, a simple construction method is chosen. 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." via thisispaper
