ARCH HOUSE was designed with the combination of the contemporary Japanese and western styles. Even though the house was a spatially limited, we tried to share the both of Japanese and Western feelings in one space together. To connect these different design languages smoothly, we used several impressive arches as the important design aspects to neutralize and emphasize the atmosphere. Also, we used lots of essential textures such as woods, mud plasters, and massive concretes. The spaces became even more natural and chic-cozy.
