Gehry & Associates.      TELLURIDE RESIDENCE Telluride, Colorado 1996– The tumbling form of this vacation home for a longtime client derives from its steeply sloped site in the Rocky Mountains, as well as the challenges posed by working with a rustic alpine vocabulary without succumbing to an overtly traditional or naturalistic form. While the design takes the language of the Gehry Residence (1977–78; 1991–92) in Santa Monica as its starting point, its fluid exterior reflects the recent shift in the architect's vocabulary toward more organically sculptural forms. This shift is markedly evident by comparison to the unbuilt Wagner Residence (1978), which responded to similarly sloped terrain in a much more unyielding manner. Clad entirely in blackened copper panels—a common roofing material—the exterior suggests a rocky mass strikingly suited to its setting yet lacking a conventional sense of familial comfort. The challenge posed in domesticating the design is carried out on the interior, which departs from the rugged quality of the exterior rather than straightforwardly echoing it. Here, the design calls for an extensive use of fabrics and other warm materials in an effort to create a cocoonlike shelter with spectacular views of the surrounding mountains.
