Most people head into the woods or out to the country to escape the city’s daily grind, but when Boston-based architects Keith Moskow and Robert Linn need a weekend away with their families, they drive to the suburbs. Their unlikely destination is a construction in Newton, Massachusetts—just seven miles west of Beantown—that they call the Swamp Hut.

The project started 20 years ago as a little house on a prairie, when Moskow, coprincipal of Moskow Linn Architects, designed a small structure for his father-in-law. The retreat was never realized, though the plans have been in and out of the drafting drawers countless times since—–winning awards as a disaster-housing proposal, an eco-resort lodging plan, and, all too appropriately, unbuilt architecture.

In the summer of 2008, the architects finally put their tweaks to the test. “We wanted to see if we could do architecture in a prefabricated, cost-effective way,” Moskow says. Years earlier, he and his siblings had inherited a ten-acre site that had since sat empty.

Only one-eighth of an acre was buildable, but that small space was enough for the 580-square-foot structure. Moskow and Linn built the 12-foot-high trusses in a workshop, then carried them down the meandering 200-yard path to the site. Over five weeks, they pieced the parts together to form four huts flanking a central square deck. It was a formidable task, but their elbow grease saved the pair an estimated $15,000 in labor, making the total cost just $7,500 for materials.

The parts and the plan have proven a success. The roofs of the huts are well suited for the winter: Snow slides off the steep pitches, and the tall, triangular spaces create shelters big enough to house the architects and their families. Most of their time, however, is spent outside on the central deck, roasting marshmallows and “trying not to burn the place down,” Linn jokes.

Linn calls weekends at the Swamp Hut “glorified camping.” There’s no running water, so they carry their own supply. They also bring nonperishable foods—–like spaghetti and hot dogs—–to cook over the fire, since there’s no electricity. There’s a composting toilet, “but it’s easier to go in the woods,” Moskow says. At the end of a visit, they haul their garbage out with them.

Chirping birds and rustling leaves drown out noise from nearby streets. The remaining sounds are the gleeful screams of Moskow’s and Linn’s kids as they explore the skunk cabbage and pussy willows. Not bad for a weekend in suburbia.
