Interlacing and floating line building are created to react with ground and roof landscape. The lines are curved horizontally to have a connection with other units and roofs; curved vertically to conquer less ground area and have better views for every unit. The existing road is buried underground just like another line which connects directly to the underground parking and separates vehicle circulation totally from pedestrian circulation above ground. By doing this, there is an intact ground landscape to fully use which is only separated by columns of pilotis.
