HOUSE IN SEIJOH
Towards Super-Sophistication in Architecture
HOUSE IN SEIJOU is a three-story residence located in an affluent residential district of Tokyo.
The design was conceived of responding to the client request for creating floor areas available to the maximum under such restrictions as the footprint less than 40% of the site area, the building height less than 10m and the sun-shadow regulation to restrain the height as well.
Within these limitations, living space was maximized by employing steel construction to minimize the bulk of the structure itself. A pair of steel portal frames, inspired by torii - the sacred gate for Japanese shrines - bear the load of the entire structure, additional columns entirely ornamental. The ground floor is dedicated to a garage and a workshop, while the upper two floors serve as living spaces entirely glassed on both the north and south side, extending to terraces guide upwards to a larger roof-deck.
Adopting shipbuilding technology, prefabricated steel-paneled rooms were arranged and welded together on site, creating a water-proof membrane. To ensure thermal insulation for both the roof and the wall, the blocks were coated with polyurethane foam. The efficiency in insulation technology resulted in an additional 6 square meters of floor area in contrast to a reinforced concrete structure.
