Originally designed and owned by architect Sam Caudill, whose projects include Aspen’s library, art museum, and airport, the Aspen Residence is located on 4.52 acres in Pitkin County, Colorado. The 1960s house had fallen into disrepair when Caudill sold it to the current owners in 2000.

The owners hired Reno Smith Architects to design two new wings to accommodate their growing family: the bedroom/garage wing to the north, and the spa wing sited to overlook the nearby creek to the west and a pond to the south that is used year-round for geothermal heating and cooling. “The shape of the plan was influenced by the existing site features,” explains project architect Scott Smith, AIA.
