Toda House, a spiral building, located at Hiroshima in Japan, has a unique design of a bird’s nest elevated a little above the ground. The elevation is provided to give it a watch-tower-like look to the building and is meant for security. The building has been designed by Japanese architect . The landscape of the region is like platforms forming several layers, placed one above the other.
The architect was asked to design a structure having a view over the roof of neighboring buildings, which are a level lower. The lower portion is left unoccupied since the client wanted to open a shop in the future. The design offers a view to the entire neighboring house. In addition, it meets all the requirements specified by the client. A penetrating staircase is used to achieve a diverse spatial outlook and the spandrel wall gives an extra-ordinary ambience to this wonderful building.
