Mission Bay is the most rapidly developing neighborhood in San Francisco. Among the numerous multi-family, office and medical buildings currently being built, Dropbox HQ, Uber HQ, and the Warriors arena will soon call Mission Bay their home. As the area rapidly gains density, the Community Center becomes a vital resource to allow for a cross section of old and new populations to gather. Additionally, the project is sited across the street from a future public K-12 school and will become a resource for after-school activities. Primary programs include fitness/yoga room, an indoor basketball court that can also be used as a performance hall, community meeting room with a kitchen, study hall and small library. It is taking advantage of California’s climate, the ground floor open to the public areas and the surrounding city. Its floor is concrete tile mix with grass tile, creating a refined plaza next to the park.  The upper level is a box that facilitates the activities of the levels below and above. Full floor trusses within make the 60 feet column-free cantilever span of the floor below possible and support the box above. By manipulating the volume, multiple levels, and different interaction are visible behind the clear facade. Transparency becomes the main character, as one of the true value of community center itself.
