This case is a design of a five-storey house. The first and second floors are public spaces, and the third to fifth floors are the independent bedroom space, study and exercise spaces for a family of five, three generations of the same family. The building is a typical penetrating house that the width is narrow, the depth of the house is deep, and the stairs are located in the centre of the building. The plane is cut into two spaces, the front and the rear, also known as the "Love Ladder", which creates low-intensity, incomplete areas and other issues.
