Before the renovation, there were many exposed lines and pipes in the aisle that can casuse accident, and it has major impact on the entire environment. After comprehensive consideration, the design uses perforated metal mesh to cover these pipes and keep them away from residents to ensure the safety of the community. During the renovation, the space on the roof was reasonably used and divided into rest area, activity area, planting area and clothes drying area. The rooftop, which has been idle for many years, finally comes back. Residents now can plant flowers on the rooftop and feel the community atmosphere.
