This is a residential house located in a new development site in Takarazuka, Japan. Because of the solid nature of the ground, we decided to make a building only by putting a roof over the sloped terrain without modifying it. The house, spread on the terraced ground, has a light steel frame of 3m x 3m. It consists of boxes, including a bedroom, a children's room and a bathroom, and a void generated by the subtraction of the boxes. On top of them is an undulating roof, whose slits allow sunlight to diffuse into the entire interior space. The interior space is affected by multiple parameters, or the interactions among them. Those parameters are concerned with direction and scale. As for direction, the interaction among the sloped ground, the grid of columns, and the inclined undulating roof of 45 degrees gives the interior a mixed character of order and variation. Furthermore, multiple scales have an influence on the space thus created. The three-meter interval of the grid, the 800mm difference in level of the floor, and the 300mm height of the roof aperture are combined to create both consistency and heterogeneity in the interior space. The relationships among different elements compose the simultaneously open and intimate space, like Italian mountain villages or an interstitial space between buildings. |
