Concrete spiral staircase disrupts linear interiors of House in Ashiya www.dezeen.com

A spiral staircase breaks the linear geometry in a Japanese house designed by Kazunori Fujimoto Architects & Associates, which is made nearly entirely of concrete.
The spiral staircase is the first feature in view at the end of the corridor.
Designed as the central feature of the home, Kazunori Fujimoto Architects & Associates gave spiritual significance to the staircase as a yorishiro.
The kitchen and living area occupies the immediate open space inside the same volume as the entrance and stairs.
Fujimoto is no stranger to delicate concrete spiral staircases, which he employed previously in House in Akitsu.
