House in Yamanoi is a minimalist house located in Hyogo, Japan, designed by K. Associates. The client is a couple who currently live by themselves. The residence was newly planned as a space to spend their life together after the children became independent. The site is an irregular shape; a small river runs on the west side, and on the other side of the river is a residential district. On the east side, Himeji Castle can be viewed beyond at the end of the front road. The design condition was very challenging, as the site was in a irregular shape, and the architect proposed the facade to show respect to the townscape.
