Longpan Park Public Toilet is on the higher ground, and with short plants around. As a result, the structure spreads horizontally in a low way. When people approaching it from the road, it can see it emerges time to time on the plants. At sunset hours, it has a opening to frame the sun. This is a eastern gardening concept called “framing”. It is like sunshine coming out from the building just like the special landscape here: the sun penetrates from the gaps between corals. The design is inspired by the Gap.

Building have great amount of shading. They has a lot of voids, from the entrance doors, to the horizontal windows near the ceiling, also the windows on the rood. It creates good ventilation, and also gives the interior abundant nature lights.

In order to reduce the artificial light pollution at night and ensure the safety of public toilets at night, indirect lighting is adopted as the architectural lighting design in this project. The lighting mode is formed by the reflection of the internal wall to the ceiling and inward and downward lighting. To make the building visible at night while minimizing the impact on the natural night environment.
