Satoshi Kurosaki of Japanese practice Apollo Architects & Associates has completed ‘Cave’ - a four-storey residence clad in galvanized brown steel sheets.

Located in in a suburban area of Tokyo, the house is defined by its tough exterior and a panoramic window that wraps around the front of the structure.

Despite the cave-like architecture, the wide rectangular window combined with a large skylight allows light to fill the home, creating a sense depth and space in the compact interior.

The home has been built to house one person, with the main living area located on the second floor, bathroom, toilet, main bedroom, and a small garden positioned on the third floor, and a wine cellar and study down in the basement.

A traditional Japanese tatami room has also been incorporated to serve as a guest room.
