This project utilizes folding surfaces as a mechanism to make a historically non-structural system, Muqarnas, into one that combines surface and structure. The resulting forms are structurally optimized, while operating as skin, aperture, circulation core, etc. The system is adapted geometrically, materially and structurally to create a viewing platform in the San Francisco bay area. A peri-style hall emerges drawing on the structural grid of the existing pier, while responding to program and urban grid, as well as the slope and depth of the ground below the surface of water. As the bay slopes away from the shore, the piers become farther apart from each other, while becoming deeper and wider. While the bays operate within a variable repetitive grid, creating smaller apertures, furniture and circulation cores, the symmetrical geometry gives way to an unfolding which translates to stairs, ramps and canopies where needed.
