Woodland Modern Retreat

In a pocket of woods not far from Walden Pond, this distinctly modern house settles effortlessly into its surroundings. Conceived as a floating architectural bar, the house embraces the property’s glaciated landscape. It seems to balance on two small hills, above a partially exposed concrete plinth. From the outset, our clients sought a home that was sensitive to the site and environment, as well as energy efficient. On the main floor, continuous glazing opens the living spaces and primary bedroom to panoramic views of a quiet pond and wetlands. In contrast to the more private and opaque north façade, this south-facing wall of glass maximizes natural light and views into the landscape. Dramatic structural cantilevers support an exterior deck and expansive screen porch.

The building envelope features triple-glazed windows, continuous roof and wall insulation, and a double-wall assembly to exceed energy conservation standards. A high-efficiency ERV mechanical system maximizes heating efficiency, and two solar arrays and a geothermal system provide additional renewable energy.

Flavin have been amazing throughout our home design process. Having worked with a number of architects in the past, I can say that Flavin is truly world class in their execution and thoughtfulness. We've spent many hours talking and meeting with Colin and appreciate his patience, honesty, and commitment to excellence. He strikes the perfect balance of creativity and professionalism that is critical for successful modern home design. The team he's assembled all share Colin's passion for creating family homes that are both beautiful and pragmatic. We can't wait to come home to the house they designed for us!
