The maisonette has an old rooftop addition. It is very common for the Taipei walkups, portraying the disorder and autonomy of living conditions. The design wants to preserve this past. Not only the original truss and decking of the rooftop addition are preserved, but also the traces of deteriorated walls are saved with clear coating. To warm up the industrial vibe, planks of pallets are reused throughout the penthouse, forming the furniture collection and the backdrop wall with color stripes. While the brick and fair-faced concrete walls help anchoring the new and old elements, balconies and roof deck bring in views of the city and nature.
