Colthoff, project architect Jon Jeronimus, and general contractor Derek Nicholson used two techniques to build the house: post-and-beam for the great room and master suite and stick-frame for the guest wing and entry area. Near the front door, there’s a special tub for the owners to wash their dogs in after hikes. The basin has a low opening and is made of durable concrete, courtesy of Mag’s Concrete Works. The wood paneling is walnut.
