House D is a minimalist house located in Tokyo, Japan, designed by Kochi Architect’s Studio. Japan-architects.com recently went to the open house of this two-storey, 114 sqm project. The interior is rather spacious with high ceilings and unique rooms that appear as cross-sections on the ground floor. There is a beautiful floor-to-ceiling bookshelf that is adjacent to the kitchen. The hardwood floors are stained in three different colors. By keeping the rooms open, the building has an almost maze-like structure.
