Thesis (Ph. D.)--University of Hong Kong, 2001. / Includes bibliographical references.

This thesis explores the notion of site as a generative basis for architecture. Site is conceived not only as a plot of land where a building is located, but also as something that is the result of agency: the architectural intervention. Site is thus constructed with architecture; it is as much a consequence as a thing. Still Creek was chosen as a provocative site in which to explore this idea. Once Vancouver's largest salmon-bearing stream. Still Creek now exists in a barren, degraded state — the result of a century of urbanization. In its fragmented course from its headwaters to Burnaby Lake, Still Creek flows above and below ground through a diversity of site conditions, ranging from a primeval ravine to a polluted industrial area. Recently, sensibilities about the stream have changed. There are presently a variety of groups interested in Still Creek, not only as a public amenity, but also as an urban ecosystem. In response, it was proposed that (1) an urban trail be located along the discontinuous course of the stream, and (2) a facility be located along the stream that addresses some of the needs of these interested groups. The Still Creek Interpretive Facility marks both the beginning of the stream and the start of the urban trail. Located at the edge of the Renfrew Ravine where the stream first emerges from a subterranean culvert, the building makes apparent the many forces present on the site. An initial gesture of excavation reveals the culvert and demarcates a constructed and a natural edge. The constructed edge of the excavation is heightened with a veil of translucent solar panels that diffuse sunlight and help power the building. A wood screen along the natural edge of the excavation acts as a foil to the alder forest, allowing the building to maintain a quiet presence in the ravine as well as creating shimmering views of colour and light. The stream fills the lowest part of the excavation, mitigating high runoff flows and making a reflective pool for light, precipitation, and sound. The excavation and screen walls form a vessel into which mute volumes are inserted, creating a variety of indoor and outdoor spaces, some relating more to site, others relating more to programme. Exterior building circulation winds through the whole assembly — an extension of the urban trail — forming a rich experiential descent from street...through building...to stream beyond...
