Prairies End is a weathered, 200-year-old barn that was moved from Ontario and converted to a dazzling, airy house with the lofty aura of a church. It faces north toward the Tetons, and inside, sun gilds the smooth heart pine floors. The massive, rough-hewn barn beams are like the pillars and trusses of a rustic cathedral. The heart of the house is a long, two story great room, anchored on each end by a wood-burning stone fireplace and a sitting area; the dining table occupies the center. Huge twig chandeliers hang from the high wood ceiling. The kitchen, with a Wolf four-burner gas range, is beside the great room. A covered porch and open deck extend from the kitchens French doors for outdoor dining, entertaining and the simple enjoyment of the extravagant view.
