As approaching the project, the design firm set two goals: renovating the old and inserting the new. The veranda functions as a circulation route, reshapes the spatial pattern and layers, and provides a playful walking experience. The front courtyard is mainly used as a garage. ARCHSTUDIO retained its pitched roof, removed the front and back walls, and shifted the entrance door to the side, so as to leave more space for parking. The middle courtyard is a public activity space. It previously contained three houses, one on the north, two on the sides. Based on its original layout, ARCHSTUDIO set a living room, a tea room, a dining room and a kitchen, etc. in this area. The designers adopted a symmetric spatial pattern, which inherits the sense of formality of traditional courtyard buildings. The back courtyard is a dwelling space, mainly consisting of two bedrooms, a tea room, and a study. The old building walls were restored, by reusing the gray bricks from demolished temporary architectural blocks in the courtyards. The floor of outdoor spaces is paved with the same type of bricks, to ensure visual consistency. Some of the new walls are formed by glass bricks, which have the same size as the old gray bricks.
