Clarke Building Company: Custom Home Additions in Massachusetts & NH
When your family outgrows your home, you shouldn't have to move to get the space you deserve. Clarke Building Company designs and builds custom additions that match your existing architecture, managed start to finish by Dave Clarke.
Home Additions by Clarke Building Company
Clarke Building Company builds custom home additions across West Newbury, the North Shore of Massachusetts, and Southern New Hampshire. Owner Dave Clarke runs every project himself, from the first walkthrough to the final inspection, so you talk to the same person the whole way through. Clarke builds room additions, master suite expansions, second-story additions, sunrooms and 3-season rooms, and structural bump-outs, and handles the foundation and permit work in-house. Every addition is built to match your home's existing siding, trim, rooflines, and windows so the new space fits the original house instead of standing out.

Custom House Additions Built to Match Your Home
Your home should grow with your family. Clarke Building Company designs and builds house additions across Massachusetts and Southern New Hampshire that fit your existing architecture, roofline, and interior flow, so the new space looks and feels like it was always part of the house.
One Point of Contact, Start to Finish
Dave Clarke manages every phase of your addition personally. No subcontractor confusion, no communication gaps, no getting handed off to someone you've never met.
Full Permit Management
We prepare and submit all permit applications, coordinate with your town's building department, and schedule every required inspection so you don't have to navigate it alone.
Matched Materials and Architecture
Siding, trim profiles, window styles, and rooflines are selected to match your existing home. The addition should look original, not like an afterthought.
Transparent Estimates, No Surprises
Dave walks your property, discusses every option, and puts together a written estimate that reflects the actual scope. You'll know exactly what the project costs before anything starts.
More Than Square Footage: Space That Fits How You Live
A good addition does more than add rooms. It changes how your home feels to live in every day. We design additions around natural light, using larger windows and, where it fits, skylights, so the new space stays bright and open instead of feeling tacked on to the back of the house.
We also think about how the space is used. Open family rooms and kitchens that flow together give everyone room to gather, while a master suite, home office, or quiet reading nook gives you somewhere private to step away. Getting both right in the same project is what makes an addition feel like it belongs.
And because every choice ties back to your existing home, the finished space reads as one house, not a main house with a newer piece bolted to the side. That is the difference between an addition that adds value and one that just adds rooms.
What Types of Home Additions Does Clarke Build?
Custom Room Additions in Massachusetts & Southern New Hampshire
Need more living space? Our room additions give Massachusetts and Southern New Hampshire homeowners the square footage they need without sacrificing the character of their existing home. Whether it's a new family room, home office, playroom, or extra bedroom, we design and build additions that feel like original architecture, not a tacked-on afterthought.
See our renovations for reconfiguring existing spaceMaster Suite Expansions
Turn your master bedroom into the retreat it was always meant to be. Clarke Building Company builds master suite additions that expand your footprint to fit walk-in closets, sitting areas, and private access, all crafted to blend with your home's existing layout and exterior.
Second-Story Additions
When your lot is tight but you still need room to grow, building up can be the answer. We add full or partial second stories to expand bedrooms and living space without giving up your yard. This work calls for a careful look at your existing structure and foundation, and Dave walks you through what your home can support before any plans are drawn.
Sunrooms & 3-Season Rooms
Bring the outdoors in, year-round or seasonally, with a custom sunroom or 3-season room addition. We build both fully insulated, conditioned sunrooms for four-season use and traditional 3-season rooms that make the most of the warm-weather months with wide views and natural light. Every sunroom starts with a proper structural foundation, quality glazing, and materials selected to match your home's exterior.
Structural Bump-Outs
When a full addition isn't required but you need targeted extra space, a larger kitchen, an expanded entryway, a wider dining area, a structural bump-out may be the right solution. Clarke Building designs and builds bump-out additions that are fully integrated into your home's structure, including proper foundation support and exterior finishing that matches your existing home.
Foundation Work for Home Additions
Every home addition we build starts with the right foundation. Whether your project calls for a full perimeter foundation, a crawl space extension, or a slab, Clarke Building Company handles all foundation work in-house. We coordinate with your municipality's requirements and make sure every addition starts on solid, code-compliant footing - literally.
Planning for In-Laws or Multi-Generational Living?
If your goal is a private space for aging parents, adult children, or guests, an attached addition is one option, but a separate accessory dwelling unit may fit your property and budget better. We build both, and Dave can walk you through the trade-offs so you pick the right path for your home.

How Does Clarke Build Your Home Addition, Start to Finish?
Adding on to your home involves more moving parts than most homeowners expect. Here's how Clarke Building Company manages your project from first conversation to final walkthrough, with Dave in constant communication the whole way through.
Discovery & Design Consultation
We walk your property, discuss your vision, and evaluate structural and site conditions. We talk through options, timelines, and realistic budgets so you can make an informed decision.
Permit Management & Town Approvals
We prepare and submit all permit applications to your town's building department, manage any zoning board requirements, and coordinate inspections. You don't have to navigate Massachusetts permitting on your own.
Foundation & Site Work
All additions begin with proper foundation work. We excavate, form, and pour a foundation matched to your home's existing conditions and your local building code requirements.
Framing, Roofline Integration & Weathertight Envelope
Our framing crews tie new construction into your existing structure, matching rooflines and creating a weathertight building envelope before any finish work begins.
Exterior Matching
Siding, trim, windows, and roofing are selected to blend with your existing home. We do not cut corners here, because the exterior match is as important to your home's value as the interior finish.
Interior Finish Work
Flooring, paint, millwork, electrical, and plumbing finish out the interior to match or intentionally complement your existing home's character.
Final Inspection & Walkthrough
We manage all final town inspections and walk the completed addition with you to confirm every detail meets your expectations.

What Homeowners Are Saying
"We hired Clarke Building Company to finish our basement. When Dave first came out, we appreciated how he took the time to really walk us through what he was thinking. He always prioritized our input but was great about sharing his ideas and suggestions. The quote we received was very reasonable..."
"We hired Clarke Building Company to finish our basement. When Dave first came out, we appreciated how he took the time to really walk us through what he was thinking. He always prioritized our input but was great about sharing his ideas and suggestions as well. The quote we received was very reasonable.
Before we even began the project we asked for a fairly decent change of scope and Dave was quick to accommodate that. That same flexible approach continued throughout the project, as issues came up or new ideas came to mind. This even included the very last day when we asked if it'd be possible to add a bar counter to one area. By the next day it was already done.
Communication with Dave and his team was excellent. He was always quick to respond and took as much time as we needed. He was proactive in giving us a heads up to make sure we were in the loop. Dave was happy to do whatever we asked but always gave us alternative suggestions that he thought might work well or save us money. We also had a similarly positive experience with the subcontractors we needed for electrical, plastering, etc. Everyone we worked with was friendly and accommodating.
The timeline we were given at the beginning of the project was near exact, which was very impressive. When the project hit challenges (like some huge snowstorms preventing delivery), Dave did whatever it took to get the project back on track.
By far though the best part of working with Clarke Building was how clearly evident it is that they really care about the quality of their work. Not just to make sure their customers are happy, but because good quality work is just something that is important on its own. Without us asking, Dave made sure all of the trim and doors matched our main floors, something I didn't even think of. He had the painters poly our basement stairs because he knew people would be coming in from outside and using them more. He gave extra thought to a tricky AC duct that we were stumped on until he came up with a great solution.
This approach to quality really stood out and showed in the finished product. As my wife and I walked through the finished basement, we couldn't find one single issue with the work, even a minor one. I would without hesitation highly recommend Dave and Clarke Building Company to anyone on their next home project."
"We had a great experience with Clarke Building Company. Dave replaced several doors and a window, as well as installed soffit vents and baffles in the attic of our home in Ipswich. What stood out was what a great communicator Dave was throughout the project. He noticed a separate issue in our attic and was proactive in taking pictures, researching options, and following up with us. From initial visit and estimate to final work, we always got timely, clear communication. He always took the time to explain everything to us, even after a long work day. We look forward to working with him again in the future."
"Dave and his team did an outstanding job on our addition. The quality of work was excellent, and you can tell they take real pride in what they do. Dave was also great about working around our schedule, which made the entire process smooth and stress free. Everything was completed on time and came out exactly how we envisioned. I would highly recommend his company to anyone looking for high-quality, reliable construction work."
