This residence has only a dozen square meters, but it can give full play to its functions and embodies elegance and comfort. The first floor is two meters high and the second floor is only 1.5 m high. So the space adopts “open to below” and the two windows near the street can address the issue of lighting. So when designer Daohua Liu was making the overall planning, he adopted the Family Art Museum design concept. Because the male host suffers from asthma, we built an oxygen system for him, through which he can directly inhale oxygen on the second floor.
