Due to the small living space in Hong Kong, it is hoped that the “Shape of Light” will allow residents to create connections between people in the open space of the split-level and bring a light sense of floating into Hong Kong's high-density cement buildings, thereby breaking the architectural grid and allowing users to have a more visual sense of rhythm. The reflectors on the top floor, combined with the light guide device, are placed in the atrium of the high building. By way of suspension, the daylight lighting time can be increased indirectly.
