White space created by the high concrete foundation and the void space

This house was built in a residential area developed on a hillside in Osaka. The inside is a large one-room space with a concrete cantilevered slab built in unison with a high foundation and a stairwell that wraps around the perimeter and houses a series of horizontal windows and two stairs. The cantilevered slab serves as a top, a free element that can be used for desks, serving tables, storage, and other purposes, and at the same time, it is intended to be a strong and independent focal point within the house.

Thin wooden columns are arranged symmetrically, and partitions are kept to a minimum, with the plan being to add more as the space changes.

The perimeter void on the second floor has lace curtains installed inside to create a buffer zone between the exterior and the interior, creating a sense of depth and white space.
