Landscape public space is not only a place to walk and stay, but also one of the most important factors is how to attract people to participate spontaneously and create interaction. The designer opens the boundary of "home" with landscape, and regards the building's 4.5-11m height, about 1,500m2 elevated floor and nearly 10,000 square meters of atrium as a complete living space. Breaking the boundaries of space, in terms of spatial continuity and quality feeling, the indoor and outdoor space forms a whole, extending the space of home to the outside.
