Allied Building Contractors LLC — Custom Home Building & Green Design-Build in Central Vermont

Jon Guiffre started Allied Building Contractors in Roxbury to handle the full construction process under one roof. As a design-build firm, Allied takes a client from the initial idea — whether a rough sketch or a set of magazine clippings — straight through to a finished home without shuffling them between separate architects, engineers, and contractors. Their focus on high-performance building means energy details and air sealing get worked out during design, not patched in after framing.

Why it’s on home.renovation.reviews

True design-build firms are uncommon in rural Central Vermont. Most homeowners who’ve hired a separate architect and then a contractor know how much slips between those two conversations — budget estimates that don’t survive the bid process, energy details that get value-engineered out. Allied’s single-contact model closes that gap. Jon Guiffre’s focus on high-performance construction means air sealing and insulation systems are part of the design, not afterthoughts. The Mad River Valley market in particular has a lot of technically demanding sites — steep lots, cold exposure, aging farmhouses — where that approach pays off.
