High-performance, net-zero-capable homes for people who care how a house is made — not just how it looks.
We build homes meant to stand for centuries and largely take care of themselves — comfortable in any season, steady through any storm, and far less dependent on the world outside their walls.
That independence is engineered, not decorative. A continuous, airtight, deeply insulated shell holds its temperature with very little input. All-electric systems, on-site power, and storage keep the home running on its own when they need to. Air is filtered and renewed without opening a window. The home is quieter, healthier, and more durable as a direct result of how it is built — and it is made to pass to the next generation in better condition than most houses reach in a decade.
Rooms that stay quiet and hold their temperature, hour after hour.
A continuous insulated concrete (ICF) envelope with almost no air leakage — mass and tightness working together.
Fresh, filtered air in every room, every day, without opening a window.
Balanced HRV/ERV ventilation with heat recovery — comfort without the energy penalty.
Comfort that holds through a storm and an outage.
All-electric heat pumps, on-site solar, and battery backup — net-zero-capable, EV-ready, grid-optional. How we reach net zero →
A home built to outlast generations of the family who live in it.
Durable assemblies and careful detailing, chosen so the structure stays sound and stays beautiful far longer than convention asks of it.
Every home is modeled before the first shovel and tested after the last. Performance isn't a promise on a brochure — it's a number we hand you.
Our inaugural build is a roughly 3,100-square-foot home in the Farmington Valley — classic in form, exacting underneath. It is the proof of the model, and the first of a series.
We build on select sites in the towns we know best — stone, trees, and hills that ask for homes made to belong there.
Alta Terra is a small Connecticut firm with an unfashionable belief: that the best thing a builder can give a client is a house they never have to think about. We do the homework — the modeling, the testing, the detailing — so the home simply works, for a very long time.
