Yi club derives from traditional Beijing quadrangle courtyard and also meet the modern aesthetic standards and functional demands. The design inherits the spatial structure of “external entity and internal emptiness” for the traditional quadrangle courtyard and eliminates rooms in the courtyards with poor daylight conditions so that each room is open toward the courtyard and embraces the landscape and sunshine. A notching curve is adopted to control the profile trend of the continuous exterior wall for a continuous building and coordinate with the concave curve below the roof, which sufficiently represents the aesthetic pursuit of Chinese traditional architectural culture.
