Surprise and delight serve as the guiding principles for this guest house. The clients, for whom John had designed the main house 20 years earlier, had a clear idea for this addition: a traditional gambrel-roof barn that would house their classic car, bicycle, and motorcycle collection with a fitness studio and guest suite on the floor above. As approached from the driveway, the structure seems completely traditional with vertical barn-wood siding; tall, narrow dormers; and a shingled roof topped by a classic cupola. Once inside, guests ascend the stairway to the upper floor and discover a wall of glass with an expansive view of the Tetons for an unexpected juxtaposition of old and new.
