Set on a scenic ocean- and marsh-front property, this 990-square-foot guest cottage was designed as a fully independent ADU that complements the main residence. Built over the footprint of a former garage to meet local zoning requirements, it includes a private entrance, full kitchen, bathroom and distinct living and sleeping areas. Despite its compact size, the cottage maximizes space and views. A 16-foot bifold door opens the living area to a waterfront patio, blurring the line between indoors and out. Above, a curved private deck extends from the bedroom. The design draws from regional Shingle Style traditions, with cedar shingles, a shake roof and subtle nautical references such as a round captain’s window and porthole detail. Inside, a palette of soft blues and whites creates a relaxed coastal atmosphere. Flexible features, including a sleeper sofa and additional bath, allow the cottage to comfortably host guests while serving as a versatile, self-contained living space.

What the judges said: Classic Shingle Style elements are well integrated and composed, proving the adapt-ability of a very American style to a compact footprint.
