This mix-use tower explores the relation of light, landscape and architecture at multiple scales. Within its dense urban context the tower reinterprets the standard tower and podium typology to create a singular form shaped to provide access to light for the smaller surrounding buildings and the center of the development, Mission Rock Park. The building is wrapped in a responsive electro-active polymer facade. With the application of an electrical current, these narrow bands rotate in relation to the sun’s position and desired lighting condition within the spaces, whether they be commercial, public or private. The responsive facade recedes is interrupted at the street level, establishing clear links between the building and its urban street context. The interruption also allows the opportunity for the park to extend beyond its delineated boundaries, cutting a canyon through the building’s facade, creating green vertical connections at every floor. The ground floor combines public, office and commercial spaces. The bottom 13 floors are designed as open large plate offices spaces, with a large atrium creating connections between floors. The upper floors are designated for small scale apartment spaces.
