Called “Parking Sections,” this project brings parking together with retail, commercial, and residential components. A “New Suburbanism” section overlaps suburban houses with big-box stores, and intersects parking garages with athletic fields. “TourBus Hotel” uses the logistics of European bus tours as a catalyst for a hotel redolent of memory and anticipation. “Park Tower” employs hydrogen technology to help create a drive-up skyscraper where a double-helical system combines a continuous parking surface with stacked retail, office, and residential zones.
