More space without the move

When your home no longer fits your family, an addition is often the smarter move than a new mortgage and a move across town. We add the room you need — and tie it into the house so closely that, from the curb, you can't tell where the original ends and the new begins.

An addition is a bigger undertaking than a remodel: there's foundation, structure, rooflines, and engineering to get right. We handle the design and the permits, and build it weather-tight and to code from footing to finish.

  • Room additions, second stories & in-law suites
  • Design & structural engineering handled
  • Rooflines, siding & floors matched to your home
  • Permits, foundation & framing built to code
Types of additions

Ways to add the room you need

Every home and lot is different — here are the additions homeowners ask us for most.

Room addition / bump-out

Extend a kitchen, family room, or primary suite out into the yard.

Second-story addition

Build up to add bedrooms and baths without giving up yard space.

In-law / accessory suite

A self-contained suite with its own bath — and kitchenette if needed.

Sunroom / four-season room

A bright, comfortable room you can use through every season.

Garage conversion

Turn an attached garage into living space, or add above it.

Dormer expansion

Open up an attic into usable, full-height rooms with dormers.

Questions, answered

Home additions FAQ

Do you provide 3D renderings?
Yes. Once your project is signed, we render your addition in photorealistic 3D and refine it with you in the design phase — so you can see and shape every detail before we build.
How much does a home addition cost?
Additions vary widely with size, type, and finishes — a bump-out is a very different project from a full second story. After a visit and a look at what's feasible, we give a clear written quote with a realistic range.
How long does an addition take?
Most run about 2–4 months of construction, plus design and permitting time up front. We give you a schedule with the quote.
Do you handle design, engineering, and permits?
Yes — we manage the architectural design, structural engineering, zoning, permits, and inspections so it's one coordinated process.
Will the addition match the rest of my house?
That's the goal. We match rooflines, siding, trim, and floor heights so the new space reads as original — not bolted on.
Can we stay in the house during construction?
Usually, yes. We seal off the work area and sequence the tie-in to keep the rest of your home livable. We'll flag up front if any phase makes that impractical.
Are you licensed and insured?
Yes — a licensed NJ Home Improvement Contractor (HIC #__________), fully insured, with a 1-year workmanship warranty behind every project.
