San Franciscos Treasure Island is an urban oddity. The artificial landmass was built by the U.S. Army Corps of Engineers in the 1930s to hosts a Worlds Fair exposition in 193940, and it later served as a naval base. Today, Bay Area planners are leveraging Treasure Island for housing, a resource in dire need in San Francisco today, among other things. Maceo May Apartments by Mithun opened there last year, offering supportive housing for formerly homeless veterans.On Treasure Island, Olson Kundig is designing a new practice facility for Bay Football Club (Bay FC), the Bay Areas first National Womens Soccer League (NWSL) team. According to Olson Kundig cofounder Tom Kundig, the design leverages San Franciscos temperate climate, and affords sweeping views of the Golden Gate Bridge, Sausalito, the Bay Bridge, and East Bay.The facility will be located on Treasure Island, an artificial landmass built in the 1930s.

The design, he said in a statement, incorporates human-scaled proportions, natural materials, and central courtyards to provide a light-filled, well-ventilated environment that enhances performance and fosters a sense of home, Kundig said. The architects are using locally sourced materials and immersive environmental graphics to reinforce Bay FCs brand identity. The design of Bay FC Training Facility reflects Californias climate and cultural history, grounding it as both a symbolic and literal center of the Bay, Kundig said. Players commit to training together, building relationships, and working as a team every day. The design acknowledges the complexity of that commitmentto the sport, the team, and the place that supports them both.According to Tom Kundig, the design leverages San Franciscos temperate climate, and affords sweeping views of the Golden Gate Bridge, Sausalito, the Bay Bridge, and East Bay.

Its more than a commercial space or an office, its personal and inviting, its a home where the team can connect with each other and sometimes host the wider community.Renderings show a low-lying building that sits nicely above a practice field, emblazoned with Bay FC iconography. The facility will have a balance of private and communal spaces, designers shared. There will be a total three training fields and dedicated recovery areas. There will also be education spaces to support career development and business training for athletes.The design uses locally sourced natural materials.
