Your local additions & remodeling contractor in Cambridge
Many Cambridge homes were built long before the materials and codes we work with today, which is exactly why additions & remodeling here rewards a contractor who has opened up a few walls locally. Waterfront Construction has been doing that across Greater Boston since 2018 — licensed, insured and owner-supervised.
Cambridge is in Middlesex County, Massachusetts, established in 1636 and home to roughly 118,000 people. That makes it one of the oldest communities in the state, so the older streets carry genuine antique stock — post-and-beam frames, hand-cut joinery, plaster over lath, and additions layered on across three centuries. We know the town well — from Harvard Square, Porter Square and Kendall Square to the quieter streets — and our additions & remodeling crews reach Cambridge quickly from nearby Northborough. It is about 35 miles from our Northborough shop — about 45 minutes to an hour in normal traffic.
Every Cambridge project starts with listening. We walk the space with you, understand how you actually live in your home, and give you straight answers about what's possible, what it will cost and how long it will take — before any work begins.
Whether it's a single room or a whole-home project, we bring the same care, licensing and insurance to every Cambridge job — and we don't consider it done until you're completely happy with the result.
For the full detail on how we approach this work — materials, process and what to expect — see our additions & remodeling page.

An addition always needs a permit, and usually more than one.
780 CMR only exempts minor finish work and small detached structures. Anything that changes the footprint, cuts into a load-bearing wall, alters a means of egress or touches the mechanical systems requires a building permit — typically alongside electrical, plumbing and gas permits. As your licensed contractor we file all of them and book the inspections.
For additions & remodeling work in the City of Cambridge, the filing goes to Cambridge's building and inspectional services department. As a Massachusetts Registered Home Improvement Contractor (HIC #196540) we pull the permit in our name, book the inspections and meet the inspector on site — you never have to take a day off for it. Requirements do change, so we confirm the current position with Cambridge's office before any work starts.
