Ushikari Renovation is a minimal renovation located in Tokyo, Japan, designed by DIMPLE Architects. Due to the clients’ children growing up, the parents wanted to evolve the space with the growth of their kids. The space is characterized by an egg-like eclipse that revolves around the internal programs, providing structure and storage. The inner side of the ellipse is partitioned into a single room, and by setting the height of the wall to 2.1 m, air conditioning and ventilation are able to pass through into the room.
