Client Testimonials
Hear From Homeowners In Your Area
Watching our home transform through this addition was incredible. Legacy Construction communicated clearly, respected our space and vision, and delivered work that feels solid and intentional. You can tell they care about doing things the right way—and building work that lasts.
We spoke with several contractors before choosing Legacy Construction and are glad we did. Their communication was excellent, and they handled every detail of our project with care. They take pride in their work, and it shows in the final product.
It’s hard to find a trustworthy contractor these days, let alone one that cares about the all the details that can easily get lost in the grand scheme of the project. Legacy Construction threaded that needle, and many others, expertly. Looking forward to the next time we can work together.
We appreciated how collaborative Legacy Construction was throughout our project. They listened to our ideas, offered practical solutions, and kept everything on track. The finished work is beautiful and built to last.

OUR SERVICES
Addition Building in Gray
You reached out to a contractor about the addition. One gave a rough number with no plan behind it. The other walked through the house and then stopped responding after the first visit without any follow-up at all.
Every month without more space costs your household:
- We show up when we say we will, every single time
- We build exactly what we planned and agreed on
- Your property value stays lower than it should without the added square footage
- The addition you put off this year will cost more to build next year
- Every season you wait is a season your family goes without the space it needs
Stop putting the addition off. Call (207) 544-4607 for a free estimate today.

Lakefront Home Additions on Little Sebago Lake in Gray, ME
Gray includes frontage on Little Sebago Lake, Crystal Lake, and Forest Lake, where additions fall under shoreland zoning that limits how close to the water you can expand and how much impervious surface a lot can carry. Adding onto a Gray lake home is shaped by those rules before the design begins. Legacy Construction builds additions across Gray, including lakefront properties on Little Sebago and Crystal Lake, confirming the shoreland zoning, designing the addition to fit the setbacks and capture the lake views, and managing the build start to finish. We design within the rules and the slope of the lot. Homeowners along Little Sebago Lake and throughout Gray trust Legacy for additions that grow a lake home, capture the views, and respect the shoreland regulations.
Mudroom and Great Room Additions in Gray, ME
Gray homes on the wooded lots near North Raymond Road and Dry Mills, and on the lake-area parcels, have the room to expand outward, which makes mudrooms and great rooms the natural additions, a real drop zone for the boots, gear, and lake equipment of a Maine household, and a gathering space a growing family needs. These outward additions match the home and account for septic where bedrooms are involved. Legacy Construction builds mudroom and great room additions across Gray, designing the storage and gathering space your home needs, matching the exterior, and confirming septic capacity for added bedrooms. We tie the new space in cleanly. Homeowners along North Raymond Road and throughout Gray rely on Legacy for the additions, mudrooms and great rooms, that make a Gray home work for the way they live.
Seamless Addition Design-Build in Gray, ME
Across Gray, from the lakefront lots on Little Sebago and Crystal Lake to the rural acreage near Dry Mills and the neighborhoods around the village crossroads, a well-built addition should match the home's exterior so cleanly that the new space looks original, while accounting for the shoreland zoning near the water and the septic and site conditions on rural land. A seamless addition integrates the roof line, siding, and proportions and ties the connection together. Legacy Construction provides seamless addition design and construction across Gray, designing the new space to match the home, confirming any shoreland or septic requirements, and detailing the connection so it is both sound and invisible. Because we design and build, the addition is grounded in real costs from the start. Homeowners throughout Gray rely on Legacy for additions that grow a home and look like they were always part of it.

Frequently Asked Questions
Can you build an addition on my Gray home?
Yes. We build additions across Gray, from kitchen expansions and primary suites to family rooms and great rooms. We match your home's siding and roof line, handle the permit, and tie the new space in cleanly so it looks original.
Will an addition affect my septic in Gray?
It can. On rural Gray lots near Dry Mills, adding bedrooms increases your home's rated load, which your septic must support. We check capacity early and coordinate any upgrade with the addition so it is permitted correctly.
Can I stay in my home during a Gray addition?
Often you can. Whether you stay depends on which rooms are affected. We seal off the construction zone to control dust and weather and phase the build so you keep use of your kitchen and bathrooms as long as possible.
Will my Gray addition match the existing home?
Yes. We match the siding, trim, and roof of your Gray home so the addition looks original. Careful detailing at the connection point, including the roof tie-in, is what makes an addition look built-in rather than added on.
What does an addition cost in Gray?
Cost depends on size, finishes, and how the addition ties into your Gray home. A single room costs less than a primary suite or multi-room build. We provide a detailed written estimate after walking the property, so you know the full picture.
Do you offer design-build for Gray additions?
Yes. We offer full design-build for Gray additions, handling plans, permits including any shoreland review near the lakes, construction, and final walkthrough. One team designs and builds so the addition matches your home and stays accountable from start to finish.
