What We Build

  • Modern tiny house with wooden exterior, black framing, and large windows; interior includes an open-concept kitchen and living room, with a detailed floor plan.

    Custom Homes

    New homes designed for New England and built to last generations.

  • House construction site with yellow siding, white garage door, and window frames, surrounded by bare trees and muddy ground.

    Home Additions

    More room, without losing what made the house yours.

  • Open concept kitchen and dining area with wooden vaulted ceiling, white cabinets, stainless steel appliances, and a kitchen island with barstools. A wooden dining table with six chairs and a unique chandelier hang above it. Large window lets in natural light, with a view of trees outside.

    Remodels

    Kitchens, baths and whole-house renovations.

  • Double garage doors with small windows at the top and black handles, attached to a building with gray vertical siding and decorative wood panels beneath the windows, on a gravel driveway.

    Garages & Barns

OUR MISSION

Our goal is simple.

Everything we build should sustain local industry, protect the environment, and offer a quality of life you’ll be proud to own. We’re proud to be a trusted home builder dedicated to craftsmanship, sustainability, and lasting value.

MATERIALS AND METHOD

The Dow Difference

We insulate with Havelock Wool and TimberHP wood fiber instead of foam and fiberglass. We frame and finish with solid wood, side with real cedar, spruce and pine, and finish with Vermont Natural Coatings PolyWhey.

Less plastic, less petroleum, nothing off-gassing into the house you'll sleep in for the next forty years. It is a healthier place to live and a quieter one, and it holds up to a White Mountains winter.

What our clients say

  • "We worked through our renovation largely remote, and from the start it was clear that we had a trustworthy and knowledgeable partner that could achieve our vision and help us make good decisions along the way."

    Steve · North Conway, NH

  • "Throughout the entire process he has been thorough, attentive, responsive, and very knowledgeable...We’ve had a great experience so far and would absolutely recommend him to anyone looking for a builder."
