At the head of Union River Bay, the architecture follows the shoreline. This Peter Forbes-designed contemporary curves around 397 feet of owned gravel-beach frontage, its wall of glass aimed across the bay to the mountains of Acadia. Built in 1995 on concrete piers that carry all the way to the roofline, the steel-and-wood structure was engineered for this exact setting: the waterside decks fold up in winter to become storm shutters for the glass wall behind them. Inside, the design brief was simplicity and light — uncluttered, gallery-like rooms with radiant heat, two fireplaces, and the signature "saddlebag" closets hung off the back of the house for exceptional storage. An art studio anchors the north end of the main house. The arrangement suits extended family and guests: a one-bedroom main house with a first-floor primary suite, and a guest house steps away across the deck with three bedrooms below and two more in the loft. A detached heated garage adds an office, a finished shop, and finished upper-level space ready for whatever comes next. 4.8 acres, 3,602 square feet, six bedrooms, four baths, generator hookup, level entry, and shoreland zoning — a genuinely one-of-a-kind waterfront compound minutes from Ellsworth and the gateway to Acadia.
