Japanese practice Kochi Architect’s Studio has overhauled a typical two-storey apartment building with the use of centrally positioned void that serves to connect eight interior rooms. Located in suburban Tokyo, the previously existing building was threatened with demolition until architect Kazuyasu Kochi suggested renovating the structure.

In order to establish both private and communal spaces, the design cuts a large void into the center of the building’s structural grid, providing new sightlines among the home’s various volumes. Each angled plywood plane has then been painted in a different color, lending the interior an abstract quality which continues throughout the dwelling. Kazuyasu Kochi contends that in the future, owing to the country’s rapid depopulation, japanese families should be able to occupy more living space, with larger room sizes.
