In the first sequence of space, for the outermost partition wall, we remove the original building’s complicated decoration and footing, and reduce its body as much as possible to get a ‘clean house’, this box exists in the street with the surrounding environment to form a ‘clean and cluttered ‘ contrast. The second layer – “insert box” forms the main body of the interior space, but this space is not enclosed, on the contrary, many windows and doors are deliberately set on the wall to allow this space to “communicate” with other spaces. The innermost area forms a relatively private space. This room is completely enclosed except for the entrance, and therefore has the highest privacy in the entire building.
