Every single review of this firm names one man. Duncan Thorne holds a Bachelor of Architecture from UC Berkeley and, by the company's own account, has been designing and building around MetroWest since 1997 — and thirteen five-star reviews across Houzz and Angi read less like reviews of a company than of a person who shows up, draws it, and then builds it. The specifics are what carry it. A homeowner writing on Angi in February 2024 described a two-car garage with a loft, built into a hillside with substantial excavation and no middle beam supports, finished in 2011 and — thirteen years on — "held up very well, with no maintenance required." Another Angi reviewer that month put a $250,000 whole-house gut at his door. In a 2020 Houzz review, a client itemised a kitchen with a built-in nook, reclaimed wood and a stained-glass window; a basement with waterproofing and an acid-stained concrete floor; and a study with a live-edge desk, a custom ladder to a loft and a diamond window. Another 2020 reviewer counted four separate projects on one house. The written record is thin on recency, though: eight of the thirteen were posted in spring and summer 2020, and the other five all landed in a single month, February 2024. The thing to settle before you sign is the paperwork. Massachusetts records show home improvement contractor registration #155595, held by Duncan Thorne, with an expiry of 24 April 2021 — verified against the registry as expired, and BuildZoom reported it still expired when it last checked in March 2026. The company's own site meanwhile advertises a current MA HIC registration and a Construction Supervisor Licence. For remodeling work in Massachusetts that registration is not a formality; it is what gives a homeowner access to the state's Guaranty Fund if a job goes wrong. One 2020 reviewer even noted in passing that Duncan is "a great architect (without the actual Lic., but years at an Arch. sch.)". So: the design talent here is well documented and specific, at a scale Houzz puts between $100,000 and $1.5 million a project. Before anything is signed, ask for the current HIC and CSL numbers, check them yourself against the state registers, and get written confirmation of insurance — and ask for a recent local reference, since most of the published praise is now several years old.

Duncan is a master carpenter with an artistâ s eye. He is passionate about designing and building living spaces that fit the specific needs of his clients. We needed more living space in our older house but also wanted keep its character. Duncan was able to realize our vision by patiently guiding us through design decisions ranging from large scale to small aesthetic details. We highly recommend him.
Duncan and team designed and built a great room addition. He is very creative and has a wonderful vision. All work and materials were of high quality. Very satisfied customer.
Duncan and his crew put an addition on our home. He added a master suite and an amazing intricate staircase and tower. In addition, he remodeled one of our bedrooms. His creative vision is top notch. I would highly recommend him and his team.
Duncan designed and built our very attractive and practical 2-car garage with loft and without any impeding middle beam supports. It required substantial excavation to build it into a hill which provided large rocks for a wall on one side. Completed in 2011 it has held up very well, with no maintenance required.
Thorne Design & Build is exceptional. Duncan Thorne is a rare combination of designer, architect, builder and has a team that works for him. He designs and builds beautiful, unique spaces from remodels to entire homes. He designed and remodeled my kitchen, basement, study initially and then my entire house which had been a total gut, in my second home. A+++ highly recommend.
