Architecture, Building and Structure Design House in sinjyo Residential Building by Kiyoshi Sugimoto The "House in Shinjo" has no windows outside. That is due to the site's unique condition, which is along the national highway bypass. The house has an inner courtyard like a hole in a square block as a device to let in light and wind while closing to the outside. The building is a wooden structure. In spite of the structural constraints, the designers focused on creating the open space that the client wanted. The interior floor plan was designed to allow the two people to live alone in a spacious and relaxed atmosphere, with a limited building area.
