built for a family that recently moved back to its hometown to raise their children in a better environment, the project occupies a large site, where the kitchen garden is located on the south and the house is located on the north side, following the shinhoshikawa river and the streetscape. the architects have worked to enhance the connection between exterior and interior, extending the eaves of the roof to create a shaded environment where residents can escape the intense summer sunlight.

six windows surrounding the structure’s perimeter bring the bright sunlight within the space, while the long dirt floor where people take their shoes off at, is located in the center of the house. ‘we think the sunlight, the wind and the smell of the earth coming in becomes part of activity of living,’ explains masatoshi hirai architects, ‘part of the local community, the environment, and the development of the family.’
