This 4,800 square-foot guesthouse is a three-story residence consisting of a main-level master suite, upper-level guest suite, and a large bunkroom. The exterior finishes were selected for their durability and low-maintenance characteristics, as well as to provide a unique, complementary element to the site. Locally quarried granite and a sleek slate roof have been united with cement fiberboard shingles, board-and-batten siding, and rustic brackets along the eaves. The public spaces are located on the north side of the site in order to communicate with the public spaces of a future main house. With interior details picking up on the picturesque cottage style of architecture, this space becomes ideal for both large and small gatherings. Through a similar material dialogue, an exceptional boathouse is formed along the water’s edge, extending the outdoor recreational space to encompass the lake. Photographer: Bob Manley
