Why Choose a Mountain Tree Home or ADU

Our homes are rooted in Bauhaus and mid-century modern philosophy, an approach that found a natural home on Cape Cod, where Bauhaus-influenced modernism settled alongside centuries of traditional New England building and the two proved surprisingly compatible — united by honest craft, modest scale, and a deep attentiveness to place. Large windows pull the landscape in. Low, considered forms sit easy on the land rather than imposing on it. Every material and proportion is chosen with the occupant's well-being in mind. A Mountain Tree home carries that lineage forward, built to belong wherever it's placed.

Every square foot of our homes is working for you. In a conventional home, unused rooms and hallways still cost money to heat, insure, and maintain. A well-designed smaller home eliminates that waste — not by feeling small, but by ensuring that every part of the space earns its place.

More space is not the same as more life. The homes that feel richest are rarely the largest — they are the ones where nothing is wasted and everything is considered. A smaller home asks something of you: to be deliberate about what you own, how you live, and what actually matters. That is not a constraint. That is freedom. Less to manage. Less to maintain. More of your time, your money, and your attention returned to you. Small, done with care and intention, is one of the most radical things you can build.

Traditionally, a conventional Vermont home has R-13 fiberglass batts in the walls and R-38 in the attic — interrupted by every stud and joist, which act as thermal bridges conducting cold inward. A typical Vermont household burns 600 to 900 gallons of heating oil each winter at nearly $3.70 a gallon, spending $2,200 to $3,300 on heat alone — before hot water or electricity are factored in. Energy costs in Vermont have risen steadily and show no credible sign of reversing. Our homes and ADUs use continuous insulation with no thermal bridging: R-29 in the walls, R-56 in the roof, and R-50 in the platform beneath your feet. The result is a home that holds heat so efficiently that the heating load drops to a fraction of what a conventional home requires — even through a Vermont winter. Add solar, and that remaining fraction disappears entirely.

Vermont household energy costs topped $7,000 in 2024, driven largely by dependence on fuel oil and propane — and there is no sign of that changing. A Mountain Tree home is engineered to cut that exposure dramatically. Add solar, and the equation flips entirely: a net-zero home that generates as much energy as it consumes, effectively reducing your operating costs to near nothing. Stable, predictable costs year after year, regardless of what the utility companies do next. Less reliance on the grid. More control over what you spend. Over the life of your home, that difference compounds into something significant.

A tight building envelope needs controlled ventilation. Our homes and ADUs come equipped with Lunos heat recovery ventilators, which continuously bring in fresh air while recovering 85–90% of the heat from outgoing stale air. Most older Vermont homes rely on air leaks for ventilation — uncontrolled drafts that waste the energy you paid to heat the space. HRVs solve this completely, and deliver noticeably better indoor air quality year-round.

The average Vermont home is over fifty years old — built before anyone understood thermal bridging, vapor barriers, or indoor air quality. Moisture finds its way into wall cavities and stays there. Combustion appliances introduce carbon byproducts. Decades of paint, adhesives, and finishes continue to off-gas into living spaces long after the work is done. The result is an environment that quietly undermines the health of the people living in it, often in ways too gradual to notice.

A Mountain Tree home starts from a different premise. A sealed, continuously insulated envelope keeps moisture out of the structure. Energy recovery ventilation cycles fresh filtered air through the home around the clock. Every material is chosen with indoor air quality in mind. You spend the majority of your life inside your home. It should be the healthiest place you go.
