This competition was intended to explore the idea of a city's "lost spaces", those interstitial places in dense urban areas that often go unrefined, overlooked, and underutilized. My partner and I sought to analyze the highway underpass spaces that are often forgotten so that we may suggest practical yet creative urban strategies for occupying those spaces to contribute to the growing fabric of Calgary, Alberta, Canada. We were inspired by the social concept of the Stoa, a civic place for gathering and sharing ideas originating from ancient Greece. We appropriated the classical colonnade form of the Stoa by imagining not concrete columns supported by a monolithic roof, but a modern structural system of scaffolding members latched onto the vacant highway overpass.
