Case of Nishinomiya

The site consists of a sloped approach way connected to the frontal road, a narrow strip of flat land stretched in the east-west direction and set at 1.2m below the frontal road, and a forest on a steep slope like a cliff on the south side. This area on hilly land was developed by a railroad company in the 1970s and is connected to the town by the only bridge that crosses the Muko River. The young family chose this place to build their new home.

A ramp used as both an approach and parking area, which seems to branch off from the slope up the hill, is placed on the north side of the site, and a terrace is placed close to the edge of the site as if projecting into the forest. The ramp and the garden underneath on the north side represent a connection to work, school and town, while the terrace and the forest on the south side represent playful weekend activities of the family and the dog, and the building is placed in between.

The first floor of the building is a one-legged reinforced concrete post-and-beam structure and the second floor is a wood structure with a deformed gable roof.  The ramp is also supported by a one-legged structure, which creates rhythms in the garden underneath. The second floor is made of 39-mm thick solid cedar flooring which doubles as the ceiling of the first floor space.   

The entire sequence–– from the ramp, through the living room on the second floor towards the forest, and to the entrance; from doma (entrance hall with a dirt floor,) down the stairs to engawa (a type of veranda in traditional Japanese houses) on the first floor; from engawa to the garden under the ramp––weaves through the town, house, and forest.
