Bartholomew Voorsanger, FAIA, says this 200-acre site in Snowmass, Colo., is “easily one of the most spectacular I've worked on.” So he felt considerable pressure to do it justice. Our judges agreed that he did. “You move through the spaces and the landscape, and the building unfolds over time and space,” said one.
Designed to accommodate a large family, the house is 200 feet long on its north/south axis, with public spaces oriented to the west and private rooms to the east. Separating those public spaces is a massive stone wall, using pieces as large as 3 feet by 5 feet. With ceilings as high as 24 feet in some areas, the wall anchors the interiors and contributes a sense of scale. Voorsanger arranged the spaces to ensure privacy and speced plenty of wood for warmth. “It was important to make it feel like a house and not a hotel,” he explains.
Abundant glass walls frame views of the nearby mountain range. But the windows' energy demand is answered by 60 geothermal wells, which provide 100 percent cooling and 95 percent heating for the home. The whole structure is topped by a copper-clad folded-plate roof that echoes the forms of the mountain range in the distance. Said a judge: “This architect really understood the power of the mountains.”
