Limited by what could be brought by ferry to Isle of Haut, architect Eric Reinholdt created a series of bite-sized volumes connected by decking.
Years ago, before they were married, Cynthia and Edwin hiked across Isle au Haut in Maine. The granite island is accessible only by ferry from the working harbor of Stonington, a seaside town on Deer Isle. On a more recent visit, the couple discovered that 80 acres were up for sale: an expanse of ferns and moss, glacial boulders, sheer cliffs, and sweeping Atlantic views.

Edwin and Cynthia, a couple from Virginia, worked with architect Eric Reinholdt of 30x40 Design Workshop to build a cabin on Isle au Haut in Maine. It comprises a series of small shed-roofed volumes connected by decking.

The parcel had been lingering on the market when the couple decided to purchase it in 2018. "It’s mostly wooded," Cynthia says. Much of Isle au Haut is protected as part of Acadia National Park, and the land Cynthia and Edwin bought, like much of the island, is "full of spruce, spruce, and more spruce," she says, "with a little smattering of maple and birch, and granite everywhere."
The couple set their sights on creating a four-season retreat on the parcel, a remote escape from their home base in Virginia. An online search led them to Maine architect Eric Reinholdt of 30x40 Design Workshop. His clean-lined work resonated immediately; they were drawn to his Scandinavian-meets-Maine fishing vernacular. It was restrained, purposeful, nature-focused.
Soon after Cynthia and Edwin met Reinholdt, they visited the site together, testing different perches and vantage points in search of the ideal placement for a home. "Part of the challenge initially was figuring out what to do with the 80 acres," Reinholdt says. "Every site has an amazing aspect. How do you choose a place to build? That was a real challenge." But one location stood out to Cynthia. She remembers getting "the feeling" at a granite outcrop overlooking the ocean, a moment that made her stop short. It feels like the house wants to be here, she thought.

Each volume—a workshop, one for the primary suite, another for the living spaces, and a screened porch—is 12 feet wide, a limitation set by the site and by what was possible to bring to the island by boat.

A workshop with a lofted area is contained in its own volume off the driveway. The primary suite partly rests on stilts, which keeps it at the same level as the living spaces and creates a sight line through to the water.
