The left half of the first floor is the dining room, kitchen and living room, the modern concept is that these three common areas together, to reduce the interference of the team rest area, the so-called "static and dynamic separation". The first floor room can be used as a studio, if we can work at home in the future, there is no need to get stuck in traffic.
