Built on the bend of a stream at the base of Sun Valley's towering Baldy Mountain, we designed and sited this new 6,000-square-foot house to take full advantage of Idaho's spectacular views even though the lot itself was highly restrictive. Reflecting the owners' peripatetic lifestyle and eclectic tastes, the house freely mixes country-French and English-cottage elements, and also provides a showcase for the owners' collection of Brazilian art. To capture the expansive views from every room, the plan emphasizes flowing spaces. A large family room/kitchen has French doors leading to a stone terrace overlooking the stream, while a center hall with a dramatic two-story stairway leads to a formal dining room with large leaded-glass windows adorned with hand-painted murals of local wildlife. The living room and master bedroom have custom-made stone fireplace mantels imported from France, the cozy library has a rustic beamed ceiling and a multipurpose children's playroom has built-in sofas that convert to beds for overflow guests.
