2019 AIA Housing Awards: Off-Grid Guest House by Anacapa and Willson Design

One- and Two-Family Custom Residences

Off-Grid Guest House

ARCHITECT: Anacapa; Willson Design

LOCATION: Central Coast, California

PROJECT SIZE: 800 Square Feet

Located on one of the last remaining undeveloped coastal areas in California, this modern guesthouse resides on a wildlife preserve—exemplifying a successful balance of residential development and ecological preservation. Nestled into a steep hillside, the residence was designed with low visual and environmental impact on the surrounding landscape. Disguised by a low-profile green roof, the home invites sweeping views of the Pacific Ocean and surrounding rolling hills through a generous amount of sliding glass, and expansive decks that cantilever over the foundation’s steep, rock face.

A high level of sensitivity to environmental impacts was exercised throughout all phases of design and construction. The guest house is completely off-grid, powered by a photovoltaic energy system. The home features LED lighting, low-usage appliances, and a private well and water treatment system. An elemental material palette of steel, concrete, and glass integrate seamlessly with the landscape and will weather naturally over time. Anacapa
