Shell Canopy, Sausalito

Year: 2025

Collaborators: Jeffrey Lew, Jacky Kuang, Joseph Phai

This project is a design assignment from the Form and Structure course at UC Berkeley. The objective was to design a canopy that provides shelter for a triangular site in Sausalito, California. The site offers expansive views of the Bay Area and has long been used for a variety of public activities.

We proposed a shell structure to achieve structural efficiency while minimizing material use. To resist strong ocean winds, the edges of the shell curve upward, enhancing both structural stability. The terrain was carefully modified to allow smoother circulation at the entrance, while also forming a gentle slope that can be used as informal seating for gatherings, performances, or simply enjoying the sunrise.

The modified terrain serves as a natural ‘theatre’.
The space beneath the shell is made more accessible as the terrain slopes downward at the entrance.
