Residents can walk underneath the building into this central courtyard, where a staircase leads up into a first floor lobby.

Here's some more text from the architect:


The site is located in a residential area developed on a gentle perch in Hiroshima, overlooking a far view of the Inland Sea and Miyajima.

The land of this area is developed into platforms form with several levels.

The architecture was requested to have a view over the roof of the neighboring house, standing one level lower, and to consider security, for the site is located at the edge of the residential area, and to leave some space for extension when the client opens a small shop in the future.
