Adopt simple and cozy Japanese living style as the interior design notion to echo the exterior pitched roof of Japanese custom, accordingly plan a multi-function Japanese-style room and a health preserving hot spring bathroom. The layout is open-concept, cut-down the unnecessary private compartments, reserved as much space for the living-dining area, the study, and other public spots. Arrange all the bedrooms on the second floor, so that parents and children can accompany each other at the same floor.
