This log cabin on Washington’s Camano Island, with stunning views of Utsalady Bay, was built in the 1940s and has been in the same family ever since. When the current owners (he’s the grandson of the original owner and builder) found themselves growing short on space, they called on architect Dan Nelson to design a two-story addition. The new wing adds a wheelchair-accessible master bathroom and a guest bedroom with an attached deck. Nelson’s sensitive use of materials and his attention to historical detail helped retain the cabin’s original ambience and charm.

The log cabin faces north and sits next to the beach on Utsalady Bay in Puget Sound. The two-story addition, set back and to the left of the original structure, has a master bathroom on the first floor and a guest bedroom with a deck overlooking the water on the second floor.

The living room in the original part of the cabin features a stone wall of granite from a local quarry. The quarry has since closed, but the clients received permission from the owners to retrieve enough granite to use in the addition, resulting in a perfect match. To the left of the fireplace, an arched doorway cut into the granite wall leads to the master bedroom. The door to the left of the arched door goes to the newly constructed master bathroom. The stairs lead to the original sleeping loft and to the newly constructed guest bedroom beyond.

The existing master bedroom features original pine walls. The green-painted sliding door was added to bring a hint of color to the log-and-stone cabin. The antique quilt on the bed is a family heirloom.

The master bathroom’s custom blue vanity brings color to the cabin’s rustic, earthy aesthetic. The vanity features a 36-inch Brockway cast-iron sink from Kohler. The floor is porcelain tile with a wood-grain pattern that matches the cabin’s “organic nature,” Nelson says. The French doors lead to the patio and views of the bay.

The wheelchair-accessible shower features Sant’Augustino tile, selected for durability, on the walls. The shower has a pebble-patterned tile floor and frameless tempered-glass door.

In the master suite’s toilet room, to the left of the French doors, Nelson installed a porthole that the homeowners found at a nautical salvage shop. The wall of split logs was originally part of the home’s exterior.

The master bath’s French doors lead outside to an exterior brick patio. Nelson added rusted corrugated metal to diversify the exterior materials of the cabin while still fitting with the original building’s aged character. “It adds a bit of modernity but respects the rusticity of the original exterior,” Nelson says.
