Garage additions
A new one- or two-car garage, with the option of a finished room, office or apartment overhead. One foundation pays for two kinds of space.
Best for: Lots with room beside the house, and families who need both storage and a bedroom.

Four ways to add space
The right one depends on your lot, your roof and what the room is for. We’ll help you pick.
Dormers
Raise part of the roof to turn a cramped attic into full-height bedrooms, a bath or an office, with real windows and light.
Best for: Capes and steep roofs where there’s floor space upstairs but no headroom.
Second-story additions
Add a full floor on top of the house and double your living space without giving up any of the yard.
Best for: Smaller lots, ranches and single-story homes where building out isn’t an option.
In-law suites & bump-outs
A ground-floor suite with its own bath for a parent or grown kid, or a few extra feet to open up a cramped kitchen or bedroom.
Best for: Multi-generation families, and rooms that are almost big enough.
The difference
Looks like it was always there
The giveaway on a bad addition is the seam: a roof that doesn’t line up, siding that’s a shade off, a step down into the new room. We plan the tie-in from the first walkthrough so there isn’t one.
- RooflinesSame pitch, same overhangs, shingles chosen to blend with the existing roof.
- Siding & trimProfile, exposure and color matched, with corner boards and window casings to suit.
- Floor heightsFloors line up with the house, so there’s no step or ramp where old meets new.
- WindowsWindow styles and sizes that fit the rest of the house, inside and out.

What shapes the price
Every addition is priced for the house it’s attached to. These are the things that move the number most.
Up or outBuilding up skips a new foundation but means opening the roof. Building out needs footings but leaves the house sealed longer.
Foundation & siteLedge, slopes, tight lot lines and access for equipment all change the groundwork.
Kitchens & bathsRooms with plumbing cost more per square foot than bedrooms and living space.
Finish levelFlooring, windows, trim and fixtures are where you can spend more or save without changing the size.

Call 781-513-9911Should I build up or out?
It depends on your lot, your foundation and how you want to use the space. Building up keeps your yard and avoids a new foundation. Building out is often simpler for ground-floor rooms like in-law suites. We’ll look at both at the walkthrough and tell you which makes more sense for your house.
Do I need a permit for an addition in Massachusetts?
Yes. Every addition needs a building permit, and your town’s zoning rules on setbacks, height and lot coverage apply. We check what your town requires at the start and file the permit for you.
Do I need an architect?
Many additions need drawings for the permit. If yours does, we’ll tell you at the walkthrough and work with your architect or engineer, or help you line one up.
Can we live at home while you build?
Usually, yes. Most of the work happens outside your existing walls. We only open into the house once the addition is closed in, and we seal off the work area to keep dust down.
How long does an addition take?
It depends on the size, the season and how long the permit takes. You’ll get a realistic schedule with your estimate, and Angel keeps you posted as the job moves.
Will the addition match my house?
That’s the goal on every job. We match rooflines, siding, trim, windows and floor heights so the addition looks original. If an exact material match isn’t available, we’ll tell you up front and show you the closest options.
