Casa H is located in the east side of Kanagawa prefecture in Yokohama city, which is situated on the east side of Tokyo in a residential area. The project is a three-level housing unit for a young married couple, constructed using reinforced concrete and completed with exposed concrete. The ground floor has a gathering space for people in the community. The second level includes a kitchen, bath, and dining room and the bedrooms are on the third level.
The house is adjacent to eight railway routes. To address the challenges of train noise and vibration, the building is designed as an enclosed space that faces the railways. The internal space is planned to minimize unnecessary movement; it is connected by a circle as a space that unites the family through a staircase. A concrete staircase generally tends to be a closed space. Hence, the floors, walls, and ceilings are lacunal spaces; this creates continuity between each spatial unit.
Since there is a gathering space for the community on the ground floor, the façade is designed to introduce the view of the architecture from the angled street. The approach from the adjacent road is intended to create a landscape that produces a sense of the breadth of the street and unity with the neighborhood.
