We modify the original facade design into aluminum grating, adopting the size of local red brick in Xiamen as a module to express the traditional form with modern material. Furthermore, the rhythm of holes in the grating is designed with parameterization according to the daily light data. As a result, there will be a gradual change of density from top to bottom, so that the daylight and heat preservation can be guaranteed. Interior design emphasizes the contrast of light and heavy, dark and light to the external facade.
