Half Cave House

It is a house where there are two contradictory spaces: an open large space and an intimate small space. The Living/Dining/Kitchen space is gently segmented with a cylindrical vault roof that floats low above the head, so that many people can be invited, while sustaining it coherence.

Originally the vault roof aims to realize a large space with few pillars, but here the focus was for the vault to be a single room, while gently dividing the space. To achive this, the cylindrical vault, span and height was made minimal and repeated with a reduced ceiling height. As a result, a room with sharp variations a ceiling height of 3380mm and a minimum height of 2080mm was created under the vault ceiling.

Due to moderate acoustic concentrations created by small vaults, sounds made by family members and their activeities gently pour down from the ceiling. This is similar to a intimacy that a cave brings to people. Inevitably, activities become small, and conversations are in a quiet voice. Wherever you are, there is a space as an extension of your body and you can feel that you are at the center.
