This is my proposal for a mixed-use tower located on the corner of 3rd and Lenora in Seattle, Washington. We were charged with creating a tower that complied (as much as possible) with the Living Building Challenge criteria. The building was to include ground-level retail, mid-level offices, and upper level residential units. The overarching concept guiding the project is the idea of a tower that acts as a microcosm of a city. It's envisioned as providing its inhabitants with all of their daily needs: a place to live, work, play, and relax. Through various incentive programs, those who work in the tower are encouraged to live there as well. In most traditional towers, program is stacked straight up, floor upon floor, with minimal interruption. In this tower, however, the blocks of program (retail, office, and residential) are pulled vertically apart, creating three distinct (mostly) outdoor common spaces that accommodate the additional program I've chosen to inject into the project. In these bright, airy, open areas there's a space for shopping, eating, and relaxing, a space for outdoor gatherings, parties, and urban farming, and a space for recreation, bars, and nightlife. In addition to these considerations, the building's form was sculpted in direct sustainable response to its environment. As a prominent design feature, the roof captures rainwater and cascades, as a waterfall, directly through the heart of the building, before ultimately being captured and stored for reuse in a subterranean cistern. Grasshopper was employed as a design tool to generate some aspects of the form, as well as calculate the potential water savings resulting from rainwater recycling. In addition to the LBC "water petal," all other "petals" are addressed and, in their respective ways, dictate form.
