Construction has officially started on the Potrero Power Station development in Dogpatch, San Francisco, following yesterday’s groundbreaking ceremony. With Mayor London Breed in attendance, the event marks the beginning of a 29-acre redevelopment that will open up a portion of the city’s eastern waterfront to the public with 5.3 million square feet of offices, housing, and retail around public parks and transit featuring designs by Foster + Partners and Herzog & de Meuron. California Barrel Company of Associate Capital is responsible for the development.
Foster + Partners announced the groundbreaking, along with updated renderings of the firm’s two residential contributions to the project. Block 7A will rise 240 feet tall with 277 new units, retail, and an infinity pool. Block 8 will stand 140 feet tall, adding 249 units, an urban farm, and other high-end residential amenities.
Phase one of construction is expected to build four commercial buildings, $300 million of infrastructure work, a 2.5-acre park, 735 units, including a 98-unit affordable housing building at Block 7B. Potrero Power Station will contribute over 2,600 apartments to the San Francisco housing market along with 100,000 square feet of storefronts, 1.6 million square feet of offices or life science laboratories, and seven acres of public parks at full build-out. Of the units, 780 will be designated as affordable housing.
While the project includes the demolition of six buildings, historic preservation will be focused on three prominent projects, Station A, Union 3 power block, and the iconic 300-foot tall concrete Stack structure. The adaptive reuse of Station A was included as part of the project following community pushback against the idea of its demolition.
The twelve-story adaptive reuse proposed for Station A features a curtain-wall addition integrated with the industrial brick structure. Herzog & De Meuron is responsible for the design. The lobby will preserve the concrete structures from the former turbine hall as an eye-catching interior feature above a recessed lounge area.
The project includes $860 million of public benefits, including an extension of the Bay Trail, a soccer field, 25,000 square feet for a YMCA, daycare, and 36 residential units for a homeless prenatal group.
Construction has started impressively quickly, 44 months after Associate Capital purchased the land. The first buildings are expected to finish by 2026, with full buildout roughly estimated around 2035. Construction will be spread across three phases with an anticipated price tag of over $2 billion.
