Temprano Construction is a licensed and insured New Jersey general contractor specializing in custom home additions in Bridgewater — rear additions, primary suite additions, kitchen expansions, family room additions, and multi-room living space. Each project is planned around how your family actually uses the house today, and how you’ll use it for the next decade. Ray Temprano leads every project personally from estimate through final walkthrough.
Bridgewater homeowners aren’t usually shopping for a different town. They’re shopping for a different floor plan — a primary suite that isn’t a converted spare bedroom, a kitchen that can handle weeknight chaos, a family room that isn’t also the homework zone. Top-rated schools and established neighborhoods make staying put the rational move. The addition is how you make the house catch up.
That changes how we plan the job. We start with daily life: where you enter, where kids drop backpacks, where guests gather, where you want quiet. Floor plan development and interior space planning come before framing decisions. Structural coordination, building permits and zoning through Bridgewater Township Code Enforcement, and every finish detail sit under one general contractor who stays reachable through the whole build.
If you already have architectural plans, we collaborate with your architect through execution. If you’re earlier, Ray can connect you with an architect based on project type and geography. Either way, the goal is usable square footage — not a box bolted onto the back of the house.

Building up over the existing footprint when lot coverage or setbacks limit outward expansion. Requires a full structural assessment before planning begins. For a side-by-side of building up vs. out, see our add-a-level vs. rear addition guide.
Extending outward is often the cleanest path on Bridgewater lots where you still have backyard depth to work with. Family rooms, expanded living areas, mudroom entries, and better flow from kitchen to outdoors — without changing the street-facing character of the home.
A dedicated primary bedroom, bath, and closet — rear or as part of a larger expansion — is one of the highest-value improvements for Bridgewater homeowners planning to stay long-term. We coordinate the suite as one scope: structure, plumbing, electrical, HVAC, and finishes.
When the existing footprint can’t support the kitchen remodeling you need, expanding outward (or removing a wall into new space) solves what a remodel alone can’t. We handle the addition and can coordinate the full kitchen scope under one GC. See our kitchen remodeling page for interior-only work.
Bedroom count, laundry, home office, and living space planned as one addition rather than a series of half-measures. Best for families who know they’ll need the space over the next 5–10 years.
When an attached garage is underused and you need square footage without expanding the building envelope as far, conversion can be part of a larger addition strategy — insulation, HVAC, egress, and finishes handled to living-space standards.
Complementary square footage when an addition alone doesn’t solve the whole problem. Home office, playroom, or family space finished properly from framing through electrical and egress. See our basement remodeling page and how to finish a basement in NJ.
The best time to address deferred work is when you’re already under construction. Bathroom remodeling, kitchen remodeling, window replacements, roofing, exterior siding, and outdoor patios all make practical sense when the crew is already on-site and walls are open. We can scope adjacent home renovation work together and present it in one itemized proposal — less total cost and less scheduling friction than sequencing separate contractors.
We walk the property, talk through how you live, and flag structural or zoning constraints early (setbacks, lot coverage, utility runs).
Plans ready? We review them with your architect. Not ready? Ray recommends a fit based on geography and scope.
Clear inclusions, exclusions, and pricing before you commit. Scope changes are priced and approved before they happen — not after.
Temprano handles the construction permit package with Bridgewater Code Enforcement. Municipal review timelines are outside our control; we plan around them and keep you informed. For NJ-wide context, see our home addition permits guide.
Framing through finishes with Ray on-site at every key phase. Some phases may require a temporary move-out window of about 1–2 weeks.
Punch list closed to your satisfaction before we call it done.
Precision craftsmanship — An addition has to look and feel like part of the original house: transitions, millwork, exterior detailing, and finishes that hold up. Ray is second-generation construction with 40+ years of combined family experience in Northern New Jersey.
Clear communication — Transparent updates on scope, schedule, and cost before changes happen. When something affects the timeline, you hear it from Ray directly — not a rotating project manager.
Built to last — Structural work, materials, and craftsmanship meet the standard a Bridgewater home demands. Client satisfaction at punch list isn’t the goal — it’s the floor.
Most custom home additions in Bridgewater run $200–$400 per square foot depending on scope, materials, and type. A rear family room addition might run $100,000–$200,000; a primary suite addition with full bath will typically run more. Plan a 10–15% contingency for conditions uncovered during demo.
Every Temprano proposal includes clear pricing with every inclusion and exclusion spelled out before you commit. We offer free, no-obligation estimates.
On financing: additions of this scale are commonly funded through HELOCs or construction loans. Bridgewater property values support the equity access most homeowners need. We don’t offer in-house financing but work regularly with homeowners coordinating bank timing.
Older Bridgewater homes may involve pre-1978 painted surfaces. When renovation work disturbs those surfaces, EPA Lead-Safe Work Practices apply — Temprano holds both the firm certification and Ray’s individual renovator credential.

Most additions run $200–$400 per square foot. Budget a 10–15% contingency for what demo uncovers. Every Temprano proposal is itemized — you know what you’re committing to before you sign. See our NJ home addition cost guide.
Yes. Additions require construction permits and typically zoning review. Bridgewater Township Code Enforcement administers building, electrical, plumbing, and fire subcode review under New Jersey’s Uniform Construction Code. Temprano handles the permit package. Municipal timelines are outside our control, but we plan around them. See also: NJ home addition permits.
It depends on lot coverage, setbacks, existing structure, and how you want to live. Rear additions often win when you have yard depth and want first-floor living space. Second stories win when you need bedrooms without giving up outdoor space. We walk both options at the site visit — and our add-a-level vs. rear addition article covers the tradeoffs.
Yes, and it’s often the right call. When walls are open and the crew is on-site, folding in adjacent renovation costs less and finishes cleaner than managing separate contractors in sequence. We’ll scope it in one proposal.
Yes. Ray is on-site at every key phase — he doesn’t hand off after the sale. If you call mid-project, you reach Ray directly. For how to vet any GC, see how to hire a general contractor in Northern New Jersey.
