Verified record
Oxbow Design Build Cooperative is a worker-owned design-build firm in Easthampton, founded in 2015 by Carl Woodruff, Chris Millette and Noah Modie and formally converted to a worker cooperative in 2019. The company runs a 10,000-square-foot facility that houses its design studio, offices and fabrication shop, with a registered architect, a licensed general contractor, a historic preservationist, and its own designers and fabricators all on staff — an unusually complete in-house team for a residential-scale builder. Its Massachusetts home improvement contractor registration is verified active by the state. The reviews, spanning 2022 to 2025, describe repeat clients who've used Oxbow for more than one project: an addition, a kitchen renovation that also winterized a three-season porch, and — most recently, in a review from the past year — a net-zero, ADA-accessible lake house the owners say they're grateful for every day since moving in. One commercial client used Oxbow for both architectural design and fabrication and praised them for holding to timelines and budgets that are often hard to pin down. Google shows 4.7 stars from 12 ratings. Beyond private residential work, Oxbow has taken on affordable-housing projects with the city of Greenfield, including a $500,000 award to redevelop a vacant lot into a duplex that will transfer to the Franklin County Community Land Trust once complete. For a design-build project — especially one that benefits from an architect and builder working under one roof — Oxbow's combination of a verified license, an in-house team, and consistently detailed, positive reviews makes it a strong option in the Pioneer Valley.

We’ve now lived in our new home for a year, and every day we’re grateful for the work of Noah Modie, Architect, and Oxbow Design Build. From the start, we dreamed of a single level, Finnish Lake House–inspired home on our pond that would also be ADA-compliant so we could age in place without significant modifications if we needed it. Noah absolutely nailed it. He kept every detail in mind, including our goal of making the house highly energy efficient and net zero, which has truly paid off. We just received a preliminary HERS and Energy Star efficiency report from our independent energy use consultant; our house is beyond “net zero,” it’s rating is -3! The design makes brilliant use of space—our 1,500-square-foot home feels open and roomy, with incredible storage tucked thoughtfully throughout. We continue to notice small design details that make daily living easier and more enjoyable. The kitchen cabinets by Oxbow Design Build are outstanding. Noah’s design gave us more storage than we imagined possible, and Oxbow’s craftsmanship delivered a kitchen that’s both beautiful and highly functional. Together, Noah and Oxbow created a home that is sustainable, accessible, and perfectly suited to its setting on the pond. After a year of living here, we can confidently say this home is everything we hoped for—and more. We can’t recommend them highly enough!
It was a pleasure to have Oxbow design our addition. They worked with us every step of the way and their expertise guided the entire project. The end result is something we will cherish forever. Thank you Noah and team!
We have had Oxbow work on many projects for us over the years. They are excellent in so many ways, attention to detail, creativity, and communication, to name a few. They are always professional, and lovely to be around! We highly recommend.
This project finished right before winter 2020. Kitchen renno and integrate/winterize 3 season porch off of kitchen. Found Carl very communicative, honest, responsive, commitment to sustainability, and "went to the mat" with 3rd party suppliers to get things right. Excellent craftsmanship, excellent sub contractors (ex. electric, HVAC, etc) . Cannot tell the difference between custom made items (cabinets, shelving) and those ordered from 3rd party. Had an in-house designer to help us with our vision and our quirky circa1900 house.
We used Oxbow for both architectural design and fabrication on a large commercial project. In a world of fluctuating timelines and estimates, Oxbow followed through on both and we were incredibly happy with the final product.
