Serving as a prototype for future communities, the project is a comprehensive transit-oriented development driven by rapid transit systems.

The Hangzhou West High-Speed Train Maintenance Base is a crucial supporting facility for the Hangzhou West Railway Hub, located 4km northwest of Hangzhou West Railway Station. It is China's first high-speed train maintenance base to incorporate transit-oriented development. The master plan encompasses a mixed-use community spanning 231,700㎡ above the maintenance base, offering residential, commercial, cultural, and educational facilities for approximately 35,000 residents. Upon completion, this visionary "city in the sky" will be China's pioneering urban complex cluster, integrating rapid transit and dual-rail linkage with the Cangqian Depot TOD.

Typically, railway infrastructure is positioned as an isolated node away from urban centers. However, this project aims to maximize the potential of the superstructure platform and utilize land resources in a three-dimensional manner. The objective is to transform railway infrastructure into beneficial components for urban life. This winning proposal is rooted in the concept of a "boundless and symbiotic vertical city ," creating an integrated and efficient three-dimensional compound community. It incorporates three metro stations and four community terminals , facilitating connectivity between various zones, including super high-rise landmarks, sunken plazas, vertically-oriented community blocks, and terraced recreational and commercial districts .

The design effectively addresses the challenges of elevation differences, vehicular diversion, pedestrian connectivity, public transit conversion, equipment layout, and urban interface. The commercial district and community terminals serve as dynamic hubs, attracting activity and creating a lively atmosphere that blends commerce and artistry within the vicinity.
