Home Additions and Remodeling
Seamless home additions, dormers, and full renovations — experienced team that treats your home like their own.
Your home is where your life happens. When it no longer fits the way you live — whether that is a growing family, a new need for a home office, or simply a kitchen that never worked the way it should — an addition or renovation is the right move. Moving is expensive, disruptive, and often ends with a house that still isn't quite right.
At North Heritage Construction, we build additions that look like they were always part of the original house. The rooflines match. The materials match. The proportions are right. That seamless integration is what separates a well-executed addition from one that just looks bolted on.
We serve homeowners across Newton, Arlington, Somerville, Lexington, Belmont, and surrounding Greater Boston communities.
From single-room additions to full home renovations — we manage every phase directly.
First-floor and second-floor additions that expand your living space without losing your yard. We design additions to match the existing structure so the finished result looks intentional — not like an afterthought.
A dormer is one of the most cost-effective ways to add usable square footage to a home. We build shed dormers and gable dormers that transform underutilized attic space into functional living areas — bedrooms, bathrooms, or offices.
Sometimes the right move is a complete transformation. We manage full-scope renovations — reconfiguring layouts, updating systems, rebuilding interiors — while keeping the project on schedule and your family's disruption to a minimum.
When you need significant space but can't expand outward, going up is the answer. We build second-story additions that are fully integrated with the existing structure — new framing, roofing, and exterior finishes that match the original home.

Home additions are complex projects. They require coordination between design, structural work, roofing, exterior finishes, and interior construction — and every transition between phases is an opportunity for something to go wrong. That's why we manage every phase directly.
From the first set of drawings to the day you walk through the finished addition, one team manages and executes every phase. You have one point of contact, clear accountability, and a result that reflects the care it was built with.
We build additions and complete renovations across Greater Boston. If you don't see your town listed, call us — we likely work there.

Yes — all structural additions require a building permit in Massachusetts. This includes framing, electrical, and plumbing permits where applicable. North Heritage handles all permit applications and inspections as part of every project. Newton and Arlington typically take 4–8 weeks to approve permits.
Most home additions take 3–6 months from permit approval to final walkthrough. A first-floor addition can be completed in 10–14 weeks. A two-story addition with full interior finish typically takes 4–6 months. We give you a realistic schedule upfront and stick to it.
A bump-out is a smaller extension — typically under 10 feet — that expands an existing room without adding a full foundation. A full addition involves a new foundation, framing, roofing, and complete interior finish. Bump-outs are faster and less expensive. Full additions create significantly more usable space.
Yes — matching the existing structure is one of the most important parts of the job. We match rooflines, siding materials, window styles, and exterior trim so the finished addition looks like it was always part of the original home.
Yes. We coordinate architectural drawings as part of the design-build process and pull all required permits directly. You do not need to hire a separate architect or manage the permitting process yourself. One point of contact from design through final inspection.
Yes — second-story additions are one of our specialties. The process involves reinforcing the existing foundation and structural walls, building new second-floor framing, and tying in a new roof. We have completed multiple second-story additions across Newton, Arlington, and Greater Boston.
Our own crew handles all carpentry, framing, roofing, siding, and interior finish work. For licensed trades — plumbing, electrical, HVAC, insulation, and plaster — we work with trusted specialists we've coordinated with for years. Our team manages the site every day.
