Green Getaway

Bloom Architecture and Haycon Building design a forward-thinking vacation home on a New Hampshire lake.

By Andrea Timpano

After years of vacationing at a family property on the shores of New Hampshire’s Lake Winnipesaukee, a Somerville couple felt ready to tackle a different kind of adventure: building a brand-new hideaway on the nearly 11-acre site, originally purchased by the wife’s mother in the early 1990s. Intended as a replacement for the property’s existing home—a small cabin clocking in at around 800 square feet—the new house would better highlight the woodsy locale while offering a more comfortable fit for the pair and their four children. It would also incorporate geothermal and passive-solar elements, in accordance with the couple’s eco-conscious values.

For design help, the husband and wife turned to Derek Bloom and Cody Pratt at Bloom Architecture, who worked alongside contractors at design-build company Haycon to bring the couple’s nuanced vision to life. At 3,374 square feet, the finished house feels distinctly contemporary, with thoughtful, view-friendly glass expanses and free-flowing spaces—to say nothing of the ground-source heating features and clever insulation tricks that minimize the home’s overall environmental impact. “I think it’s a nice medium ground between capturing the value and beauty of the site and balancing [sustainability] needs very well,” Haycon partner David Bemiss says.

Set the Mood

Contemporary style with a touch of cabin-chic dominated the plan for the interior of the home, which acts as a lake house during the warmer months and a ski house come wintertime. “We knew that the house would be modern, but I also wanted to integrate timeless and iconic cabin things—the antler chandelier [in the living area], the pine paneling, the slate flooring—because that’s my traditional experience of New Hampshire,” the wife says.

Minimize Impact

Sustainable touches aren’t limited to the house’s envelope: They appear throughout the finishes, too, from the Plyboo “Stiletto” flooring—made from responsibly harvested bamboo—to the LEED-certified Benjamin Moore paint. “Anytime we could get a low-impact, sustainable product for the interior, that is the choice we made,” the husband says.

Build Mindfully

To fulfill the couple’s request for an eco-friendly home, the team erected a double-walled structure, which allowed them to “super-insulate” the house, prevent energy loss, and “reduce the loads for heating and cooling,” Bloom explains. Plus, the house’s temperature is managed by a geothermal heat pump, which eliminates the need for fossil fuels. Another piece of the puzzle? The triple-paned windows, which were methodically placed to filter in sunlight and assist with heating.

Love the Land

When it came to the clearing for the new house, Bloom says that fostering privacy and “respecting the forest” were top priorities for the team, who worked to preserve as much of the tree line as possible while still affording ample views of the lake. New Hampshire–based Terrain Planning & Design, meanwhile, took the lead on landscaping, incorporating found boulders and low-maintenance native plantings into the scheme, which also features a fire pit.

Geothermal Energy

Heat derived from the earth. Per the U.S. Department of Energy, this clean and renewable resource is harnessed by drilling wells that tap into hot-water reservoirs beneath the earth’s surface.

Passive Building

A set of design principles “used to attain a quantifiable and rigorous level of energy efficiency,” according to Passive House Institute US. These include continuous insulation, an airtight building envelope, high-performance windows and doors, heat- and moisture-recovery ventilation, and a low-energy heating/cooling system.

Zero-Energy House

A residence that produces at least as much energy as it uses, “leaving the occupants with a net-zero energy bill and a carbon-free home,” according to the Zero Energy Project, an education-focused nonprofit.

“It’s helpful to start the design of a new sustainable home without a preconceived notion of what it will look like. When you’re prioritizing sustainability, the forces of the site, the sun, and the requirements of the envelope will begin to give the house form. Of course, we remain in control of what the house will look like, but we let these performance issues inform all decisions.”

Force of Nature

Paul Lukez Architecture harnesses the sun to power a couple’s home and car in Harvard.

By Rachel Kashdan

After a Lexington couple heard about a net-zero-energy project that architect Paul Lukez had recently dreamed up for another family in town, they quickly got in touch to see if Lukez’s firm could help them design something similar. “They were in the process of retiring and were thinking about the next stage of their life and building a net-zero-energy home,” Lukez recalls. Their first task after teaming up with Lukez? Finding the ideal plot of land for their eco-oasis. After months of searching, they eventually discovered a tree-filled spot in Harvard: a rocky site that bordered conservation land and had once been part of a farm.

Fast-forward through a nearly two-year design-and-construction process, and the area now boasts the couple’s 2,200-square-foot home. Utilizing passive-house design principles, a sprawling rooftop solar array, and onsite batteries to function as an energy-independent dwelling, the space feels comfortable for two while blending seamlessly into the landscape. “It’s a promising model for the future,” Lukez says. “We may be at a tipping point where through a combination of technological, financial, societal, and other [factors], people will increasingly integrate these kinds of ideas and systems into their own homes and neighborhoods. I believe it bodes well for a greener, more carbon-free environment.”

Tighten the Envelope

Windows on the south side of the home stream in light while their triple-glazed panes and the walls’ 12-inch-thick insulation help retain the sun-generated warmth. On hotter days, meanwhile, the roof’s large overhang provides enough shade to prevent sunlight from overheating the house’s interior.

Gather Energy

Fifty-six solar panels power both the house and the couple’s electric car. Lukez’s team also outfitted the home with two batteries that store enough energy to sustain it without sunlight for about four days. “Energy is collected by the solar panels during the day, but most people use their homes more at night,” Lukez says. “You can collect that energy and put it into the batteries so when [the clients] come home at night and want to turn on the lights, they’re running it off the batteries.”

Streamline Interiors

The inside of the home—which features a sleek wood-burning stove—is sunny, simple, and highly efficient. “They wanted everything to be pretty compact. A lot of spaces serve double functions,” Lukez says.

Embrace Natural Beauty

The couple opted for finishes with an organic feel, such as slate-colored porcelain tile flooring and custom walnut kitchen cabinetry from Michael Humphries Woodworking. Not only do these materials match the scenery outside, but they also provide a clean backdrop for books and artwork the pair has collected while traveling over the years (think: a large wire sculpture by local artist Steve Lohman).

Staying Power

ZeroEnergy Design creates a durable eco-oasis on the South Shore.

By Rachel Kashdan

While a Hingham couple loved their secluded property with views of a neighboring marsh, they were no longer enamored with the ’80s-era house that sat upon it. “They were looking for a new home that would make better use of this site,” says Stephanie Horowitz, managing director of ZeroEnergy Design, the Boston firm the pair hired to build them an updated house on the property. The two also wanted their new digs to allow them to live a greener lifestyle. “They felt that going net-zero would be the most [enduring] and ecologically responsible option,” Horowitz adds.

So the team got to work, building a 4,200-square-foot dwelling that embraces the natural surroundings (picture: multiple decks and a large vegetable garden). Thanks to a private guest studio above the garage, it also offers their young adult children a place to feel at home while visiting. As for the couple’s net-zero-energy plans? The house sports 36 rooftop solar panels, extra insulation, and efficient ventilation, heating, and cooling systems. “It’s really a wonderful living environment for the homeowners,” Horowitz says.

Elevate the Entryway

Horowitz and project manager John Mucciarone designed a sustainably forested ipe-wood staircase to connect the driveway to a deck on the second level, which comprises the house’s main entry, the kitchen, and the dining and living areas. “The placement of this stair invites visitors up to where you’re presented with this beautiful view of the marsh,” Horowitz explains.

Take It Outside

To maximize the home’s connection to the outdoors, Horowitz designed distinct al fresco living areas for each of its levels. The second-floor deck, which connects to the kitchen through an oversize sliding glass door, includes a built-in grilling station and a dining area. Meanwhile, one story down behind the garage, the architect positioned a jacuzzi with an adjoining outdoor shower.

Cut Consumption

Achieving a net-zero-energy status began with sealing the building envelope using a thick layer of continuous insulation, which Horowitz likens to a “winter jacket,” as well as incorporating triple-glazed windows. Then, to avoid using fossil fuels, the team opted for an air-source heat pump that relies on electricity. “The operational energy can be offset with the energy generated by the onsite solar panels,” Horowitz explains.

Practice Restraint

Horowitz calls the couple’s vision for the home’s interior, with its white-oak flooring and neutral paint colors, “simple and modern.” The goals were to create spaces that flow easily from one to the next (cue: the circular, open-concept layout of the main floor) and maximize panoramas of the site. In the living area, for instance, an 8-foot-tall window that wraps the corner near the gas fireplace shows off the grassy marshland.
