Home Additions · New Haven & Fairfield Counties
Additions that look like they were always there.
Second stories, in-law suites, primary suites, great rooms, attached garages. Engineered properly, permitted properly, and tied into your home’s structure, roofline, and siding — by the contractor that installs roofs and siding for a living.
01 — What We Build
More house. Not a different house.
Major additions are structural projects — foundations, framing, roof, exterior. We treat them that way.
01
Second-Story Additions
Double your square footage without losing an inch of yard. Engineered loads, a new roof structure, and a build sequence that keeps your house dried-in.
02
In-Law Suites & ADUs
Independent living space for family — or rental income. We handle the zoning questions, separate systems, and code requirements that make an ADU legal.
03
Primary-Suite Additions
Bedroom, bath, and closet space built to the standard of a new home, because under our NHC license, that is literally what we build.
04
Great Rooms & Family Rooms
Big, open, light-filled space with the spans and structural steel done right — not a bump-out pretending to be a room.
05
Attached Garages
Two- and three-car garages tied into the existing structure, with bonus rooms above when the plans call for it.
06
Dormers & Roof Raises
Full shed dormers and roofline changes that turn dead attic space into real living area — from the contractor that installs roofs for a living.
02 — Structural Work, Done Right
Anyone can add square footage. Few can hide the seam.
The hard part of an addition isn’t the new space — it’s where new meets old. That junction is engineering, framing, roofing, and siding all at once, and we do all four in-house.
Engineered, Not Eyeballed
Every addition starts with structural engineering: footings sized to soil, beams sized to loads, and drawings the building inspector signs off on.
Real Foundations
Additions fail at the foundation. Ours get full footings and frost walls tied into the existing structure — no piers-and-prayers construction.
Tied In, Not Tacked On
The difference between an addition and an eyesore is the tie-in: floor heights that line up, framing married to the original structure, transitions you cannot find.
Rooflines That Match
We built our name on roofing and siding. Your addition gets a roofline that flows into the original and siding that matches — so it never looks "added on."
03 — The Roofer’s Advantage
Most GCs sub out the roof and siding. We are the roof and siding.
PRC earned its 23 five-star reviews on roofing and exteriors before expanding into full general contracting. On an addition, that means the tie-in — the single most visible, most leak-prone part of the job — is handled by our own W-2 crews, not the cheapest sub available that week.

Home Addition Questions, Answered
Will the addition look like part of the original house?
That is the whole point, and it is where doing our own roofing and siding work pays off. We match or tie in rooflines, blend siding profiles and colors, and align trim and window lines so the addition reads as original construction — not a box stapled to the side of your house.
Do I need an engineer for an addition?
For anything structural — and every real addition is structural — yes. We coordinate the structural engineering, incorporate it into permit drawings, and build to it. Second stories in particular live or die on load calculations, and we do not guess.
Can we live in the house during construction?
Usually, yes. We sequence the work so the existing house stays sealed, secure, and functional as long as possible, and we tell you honestly which weeks will be disruptive. For second stories, we plan the roof-off phase tightly and keep the structure protected.
How long does a major addition take?
Most substantial additions run 3 to 6 months from permit approval to final inspection, depending on size and site. Second-story additions trend longer. You get a written schedule before we start, and Pat keeps you posted as it runs.
Do you handle zoning, permits, and inspections?
All of it. Setback checks, zoning applications where needed, building permits, and every inspection through the certificate of occupancy. PRC Builders holds HIC.0661478 and NHC.0016349, carries $2M in coverage, and you can verify both licenses at elicense.ct.gov.
