Home Additions and Remodeling
First and second-story additions, full renovations, and home expansions across Greater Boston.
More Space, Done Right — Without Disrupting Your Life
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.

Service Scope
What We Build — Home Additions, Dormers, and Full Renovations
From single-room additions to full home renovations — we manage every phase directly.
Home Additions
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.
Dormers
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.
Full Home Renovations
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.
Second-Story Additions
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.

Common Questions
Frequently Asked Questions
How much does a home addition cost in Massachusetts?
Home additions in Massachusetts typically range from $200 to $400 per square foot depending on complexity, existing structure, and finish level. A first-floor addition generally runs $80,000–$150,000. A two-story addition with full interior finish typically starts at $200,000. We provide a detailed, itemized estimate after walking your property.
Do I need a permit for a home addition in Newton or Arlington?
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.
How long does a home addition take?
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.
What is the difference between a bump-out and a full addition?
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.
Will my addition match the existing house?
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.
Do you handle architectural drawings and permits?
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.
Can you add a second story to my existing home?
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.
Do you use subcontractors?
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.
