A sustainable vertical community in San Francisco, CA that engages the street and fosters a beautiful, healthy living environment. A curving elevated highway once directed the flow of heavy vehicular movement across the site. Today, the extrusion of this curve as a vertical community would instead direct pedestrian traffic into a secluded urban oasis. This oasis is linked to busy Folsom Street via a passage that cuts through the bottom two floors of the building, changing the flow and slowing the pace of foot traffic. A secondary skin of operable panels harvests solar energy and controls sun exposure for residential and hotel guests as it curves down the building, culminating in a series of trellises that shade the rooftop gardens of restaurants and retail spaces below.
