The owners of the house are a young returnee couple. Unlike most of the houses I have seen before, the owner does not live here for a long time. This duplex in his hometown serves as a vacation home after work and a place to stay with his family. And the planar door model that develops new here, in the market also relatively rare. The internal height of the project is nearly 2.9m, 20 cm higher than most residential areas. In addition, 6m*6m empty living room also makes the interior have an unparalleled sense of space and liquidity. Therefore, how to strip off the unimportant decoration, fully show the house characteristics, and create a free atmosphere is the main consideration of the design.
