Designed by Tokyo-based practice Tezuka Architects, this 2,650 square foot house is supported only by its central core and by two a pair of extremely thin steel columns.
The three story contemporary home is located in Setagaya-ku, one of the 23 special wards of Tokyo, Japan, and was completed in 2000.
The best part of the house is the ground floor level with no walls: the internal space are extending 360 degree out to the garden!
Wall-less House by Tezuka Architects:
“This large site in a dense residential neighborhood in Setagaya-Ku district in Tokyo provides a rare opportunity to open the house completely to the landscape and environment, like a retreat villa in the countryside. Occupying only 20% of the site, the house leaves ample space around it for a truly open, continuous space, a wall-less house.
Using a lightweight steel, load bearing frame structure, the axial loads are distributed through only a utility core in the center and two thin columns, therefore opening the living space to the outside completely on all sides.
