House in Dawanglu is a minimalist house located in Beijing, China, designed by Tsutsumi & Associates. This is a renovation project for residence in Beijing. By changing the closed kitchen to the open one and putting the study room in the part of the dining space which had been too large before, comfortable size and openness was realized. The front of the louver door that separates between study space and dining space is flat, but the opposite side of it is manipulated to a waving curved surface. By being able to feel the liquid fluidity from the solid surface, uniqueness is buried inside the ordinary.
