CITY MANSION is the product concept of CIFI-6. The project is planned to have 11 floors of houses and 18 floors of small heights. The overall planning continues the urban fabric, and the facade design integrates the golden proportion smile curve to form the surface with lines, and the double lines change to form the rhythm and the rhythm like piano keys. Multiple elements are combined and blended into a whole. The curve of the roof echoes the theme, which is like an open embrace welcoming the owner to return home and breaking the stiff and flat skyline above the city to form identity.
