Shigeru Ban planned the single-storey Villa at Sengokubara with a radial arrangement, creating a sequence of rooms that each face inwards towards the central courtyard.

The roof of the house angles gently inward, creating a canopy around the perimeter of the courtyard, and it varies in height to create lower ceilings at the building's entrance.

Timber columns and roof joists are exposed inside the building, and line the ceilings and rear walls of every room.

Spaced wooden slats form partitions and doorways between some rooms, allowing views between spaces.

A wooden staircase leads to a mezzanine level beneath the highest section of the room, which looks out over the main living and dining room.

Two study rooms are tucked away behind, while the kitchen and main bedrooms are positioned just beyond.

With the main living room centred on the interior courtyard, all spaces are arranged in a radial manner from the entrance.

The eight sliding doors separating the main living room and interior courtyard can be opened at any time so that the space can be used as one.

The structure is made up of wooden columns and beams, which are 75mm x 350mm L‐shaped pieces, also arranged in a radial manner, creating a large one way sloped roof.
