For the only high-rise modular tower in a high seismic zone in America—and the tallest modular building on the West Coast–our first priority is planning for an earthquake. But beyond that is where it gets truly interesting. We designed a tower to fit in . . . even while it stands out. The San Francisco Modular building is located on Market Street, between two historic buildings, the Chancery Building and the Finance Building, and down the street from an architectural gem: Willis Polk’s Hobart Building. To play nicely with our neighbors, we first broke down the massing of our tower into four parts to decrease its visual dominance. Then we created a sense of harmony at the street level with a façade patterned to emphasize depth, shadow, and texture, like the facades of our neighboring buildings—albeit with steel mesh instead of terra-cotta.
