Home Addition Construction
Home Addition Contractor in Ware, MA & Western Massachusetts
Your family grew, but your house didn't. Before you start shopping for a new place — with the mortgage rates, the moving costs, and the hassle of pulling the kids out of school — consider adding onto the home you already love. G2 Construction builds seamless additions that look like they were part of the original house.
Why Ware-Area Homeowners Trust G2 for Additions
An addition is major surgery on your home. The tie-in to the existing structure has to be right — matching roof pitches, tying into existing framing, blending siding so you can't tell where old stops and new starts. That's detail work, and it's the kind of work that separates a good contractor from a call-back waiting to happen.
At G2, the two owners run every addition job personally. We don't sub out the framing and show up for the walkthrough. We're there when we open up your wall, we're there when we set the ridge, and we're there when we hang the last piece of trim. That's how additions get built without surprises.
Because we operate lean — no showroom, no sales team, no overhead you're paying for — the money goes into your project. Better windows, better insulation, a roof that ties in clean. We're based right here in Ware, so warranty calls don't get routed to a 1-800 number.
Our Process
How Your Addition Gets Built
Design & Estimate
We visit your home, measure the existing structure, and talk through what you need. You get a detailed written estimate with a clear scope — no allowances that balloon later.
Permits & Construction
We pull the permits, prep the site, and tie the new structure into your home. We coordinate around your family's schedule and keep the disruption as short as possible.
Finish & Walkthrough
Once the addition is complete — trim painted, floors down, fixtures in — we walk it with you room by room. You don't sign off until you're happy.

Home Addition Pricing
What Does a Home Addition Cost in Western MA?
Additions vary widely based on size, complexity, and finish level. A simple mudroom bump-out is a very different project than a second-story master suite. Rather than guess with square-foot averages that don't mean much, call us at (413) 277-5066. We'll look at your house, talk about what you need, and give you a real number — not a range so wide it's useless. No charge for the estimate, no pressure to sign.

Common Questions
Home Addition FAQ
Can we stay in the house during the addition?
In most cases, yes. We phase the work so your kitchen and bathrooms stay functional. When we open up the wall to tie in the new space, that's usually a day or two of disruption — we'll let you know in advance so you can plan.
Will the addition match my existing home?
That's non-negotiable for us. We match the siding, roofline, window style, and trim so the addition looks like it was always there. We've had neighbors ask homeowners when the house was built, not realizing half of it was new.
Do I need an architect for a home addition?
It depends on the scope. Simple bump-outs and single-room additions usually don't require an architect — we handle the design and structural engineering. For larger or more complex additions, we work with local architects and can coordinate that for you.
How long does a home addition take?
A single-room addition typically runs 8–12 weeks from foundation to punch list. Second-story additions and in-law suites with full kitchens and baths can take 12–16 weeks. We'll give you a detailed timeline before we start.
Can you add a second story to a ranch?
Often, yes. It depends on the existing foundation's capacity. We'll assess the footings and framing during the site visit. If the foundation can handle the load, a second-story addition can double your living space without touching your yard.
Do home additions need to meet current building code?
Yes. The new addition must meet current Massachusetts building code, including energy requirements. We build to code and handle all inspections. In some cases the existing portions of the home may need minor upgrades where they connect to the new space.
