Reviving upside-down architecture : using a historically transitional form of parking to reduce the impact of cars in mixed-use commercial areas

摘要

In the quest to reduce American automobile usage, critics have pointed to abundant and free parking as the root of a self-reinforcing pattern of scattered development that has led to a narcotic-like automobile dependency. Progressive planners maintain that the presence of parking is detrimental to creating efficient, compact communities. But history shows that's not necessarily so. In the 1940s, Sears, Roebuck located some of its stores on streetcar lines and also provided parking on the roof, making the store accessible to both pedestrians and drivers. At the time, rooftop parking signaled a transition from density to sprawl, and from a transit-based transportation system to the auto. This thesis investigates whether this building typology can be used in reverse-to usher in another transition, this time revitalizing suburban settings toward compact development patterns that can support walkability and transit. Three contemporary urban examples, in Los Angeles, Cambridge, and Boston, illustrate the suburban center redevelopment potential of "upside-down" buildings, the top-heavy stacked construction that puts parking above retail. Initial findings suggest, first, that strategically designed parking can encourage people to park once and walk to multiple destinations.
