The project is located under Yen Chow Street elevated highway in Sham Shui Po. The site sheltered by a massive highway structure has no vehicular connection and laying with densely complex underground services. Its lack of daylight, strict height limit and absence of vehicular access pose extremely harsh conditions to architectural design. The client aims to vitalize this formidable urban desert by establishing an urban forestry education centre.

The centre is planned with five lightweight prefabricated steel structures organically integrated to the expansive space under the elevated highway. Interior and exterior inter-mingle and create a variety of activity and service spaces. Visitors are delightfully able to explore in it and learn the gifts by urban trees through engaging activities. The project showcases accomplishing an architectural solution flexibly and economically for an urban site with severe limitations.
