Home Grown: A Wooden Home in Vermont

More than anything else, the use of local materials—many lifted directly from the site—lend this exquisitely designed Vermont home a solid, organic beauty.


The washbasin and mirror in the basement bathroom are built into the basement fireplace’s chimney massif. In addition to incorporating stone from the site, this bathroom features Vermont marble and tile, and a wooden door designed by the architect.

When Architect David Sellers received an assignment to build a home in Vermont’s Green Mountains on a sharply sloping, uncleared woodland site, he didn’t hesitate to take on the difficult project. In fact, he thought of it as an exciting chance to flesh out his ideas for reducing both the eyesore factor and the environmental impacts of building in a relatively unspoiled setting. It didn’t hurt that the client offered what every architect dreams of—a nearly unlimited timeline and a great deal of budgetary and creative control. Sellers had already proved his mettle: Named one of the world’s 100 foremost architects by Architectural Digest, he had achieved recognition for his emphasis on designing with nature as well as his work with pedestrian and human-scale settlement patterns. The prospective homeowner did give Sellers a few important guiding principles: He asked that the home reflect the Japanese architectural traditions he’d come to love through visits to his daughter-in-law’s homeland—simple, natural materials and a connection to the surrounding environment—and he wanted trees to be in the forefront of the design.

A dainty footprint

Sellers began to plot a scheme for a structure that would seem to grow right out of the hillside. “We tried to leave the immediate surroundings wild. There’s no lawn or garden, just a few native plants for minimal landscaping,” he remarks. “An inch away from the house is wilderness.”

Sellers carefully considered all of the treasures that clearing the existing site would offer up, from huge stone slabs to stately, solid trees. He explains, “It’s like a game of rock, paper, scissors. You look at the choices available to you, all of which might work, and consider factors like aesthetics and embodied energy. Perhaps the first choice involves very low embodied energy and is essentially free because it’s found on-site. The second choice might be economical as well because it’s mass-produced, but it involves a whole lot of embodied energy because of manufacture and transportation. Then you have to think about what other materials you’ll have to use to go along with it. For example, if you put in milled two-by-fours, you have to use a lot of other materials to cover them up and support them, and that involves more embodied energy.”

Once local stone and salvaged trees were selected as the major building materials, Sellers created a design that relied on unsawn timber as the structure’s vertical supports. Construction began in 1996, but the house wasn’t completed until two years later. Rick Moore, the contractor, had to throw out all conventional timetables and procedures and give in to the demands of the site. “The land was so hard to work on,” he says. “We had to start at one end and work to the other, piece by piece, in a sort of backwards fashion. All the retaining walls and landscaping were done before we started on the house. The framework of the tree supports was put in place first, and everything was cut with chain saws, so it was slow work. We did the framing through the winter.”

Sellers’s approach to the project was collaborative and organic in nature, to say the least. Moore remembers, “There was never any true architectural drawing, just sketches. They gave us a pretty good idea, but all of the detailing was a surprise. Only the foundation had true blueprints. And Sellers wasn’t working very far ahead of us. We used a clay model as our guide—and we had to resurrect that from the architect’s dumpster.”

Looking at the holistic beauty of the finished project, dubbed “The Tree House” because of the extensive use of unsawn timber, one might find this story a bit hard to believe. Yet how could a house that seems so unusually grounded in its place possibly have been created with conventional building practices? The roofline echoes the surrounding ridges and is designed for snow to pile up on its uphill, near-to-the-ground side so the house blends in with the winter environment. As Sellers explains it, “It’s designed so that, when the roof is covered with snow in the winter, you can’t even see it from that side.”

Because the house follows the site’s natural curves, it was necessary to place the entrance at one end, with the main hallway along the contour line. This means that all of the public spaces—living room, dining room, eat-in kitchen—are on the downhill side with the view. The house snuggles up against the hill and opens up dramatically to the outside, taking full advantage of natural daylight.

Local flavor

The concept of using indigenous materials for The Tree House was a top-down decision, starting with native Vermont slate for the roof. “Then we realized we’d have big rocks pulled from the site for the foundation, so we started refining it even more—using peeled logs from the site for the interior structure,” says Sellers. The house really shines in these interior details, which reflect Sellers’s commitment to bring outside materials in and remain true to the natural beauty of the surroundings. For an elegant design solution, Sellers warns, “Don’t use rocks if you don’t have rocks on your site. Use what meets the main criteria for value, which is based on perceived appropriateness for the site.” The happy result of such a decision is that it leads you naturally to support the local economy and craftspeople, who are adept at working with native materials.

About one-third of the The Tree House’s ver­-tical supports are trees from the property. Because they are unsawn, their inherent warmth, sound-absorption quality, and strength are preserved. None of the wood is stained, and some trees retain their bark. Sellers explains, “The logic of using a tree you have to cut down to clear the site, instead of a milled two-by-four from a tree cut down thousands of miles away, is that it adds flavor and sculptural quality and a connection to the local environment that’s impossible to get any other way.”

The beauty of the majestic trees is deceptively simple. “To remove the bark on some of the pillars,” Moore remembers, “we had to hand peel them and then clean them up with mallets. They are all sealed with Verithane, a water-based urethane. We put hot paraffin into the tree joints as needed to slow drying and prevent curing and splitting. But the trees are shrinking a little bit, as we expected.”

Sellers wanted the skeleton of the building to be apparent, so that the lines can be visually traced throughout the house. The big trees go from the upper floors all the way through to the basement, making the structure clear and understandable. “The elegance then comes from simplicity, rather than a lot of elaborate, decorative elements,” he says. “The house is designed to unfold as an experience. Upon entering, you walk down a long hall through the ‘muscles’ of the trees lined up along the hallway, with the main spaces opening up to your right with the windows framed by big trees.”

Common cents

For many people, the choice of local building materials is as much about their wallet as it is about aesthetics. In The Tree House, much of the flooring, trim, and doors is beech wood because Vermont was experiencing a beech blight in the late 1990s. The team salvaged some of those dying trees and had them milled and dried. The beech blended right in with the other materials. “Favoring local timber sources over the more popular Western timber species is akin to the growing popularity of microbreweries,” Sellers says. “People want that local flavor.”

There was other similar good fortune. Looking for trim to match the slate roof, Sellers called several salvage yards until he finally hit the jackpot. One had just demolished an old school and had fifty old slate blackboards. “I said, ‘We’ll take all of them!’” he says. To turn this amazing find into workable trim, Sellers turned to the same local expert—an experienced slate installer hailing from a long line of slate men—who had applied the slate roof. The sauna building, with walls built entirely of these recycled slate blackboards, was added as the final touch. It has no foundation; to avoid disturbing the topsoil, the crew drilled holes and inserted stainless steel pipes into the bedrock for supports. “The building sits like a spider, with pins locking it into the ground,” says Sellers. “Water can run undiverted under it.” Troy Osborne, a member of Sellers’s firm, likens the collaborative effort of architect, contractor, and homeowner to the process of making a film or performing in a jazz group. “It’s taking a unique concept, adding particular players, and seeing what comes of it.” As the head of that ensemble, Sellers is pleased that everything came together so pleasantly. “As an architect, I can only argue my case for a short time—while I’m working on the project. So in the end, the building must be a self-evident statement about materials and design working together that lasts after I walk away.”
