Temprano Construction is a licensed and insured New Jersey general contractor specializing in custom home additions in Westfield — second-story additions, primary suite additions, kitchen additions, family room additions, and more. Each one planned to integrate with the architectural styles that define this neighborhood. Ray Temprano leads every project personally from estimate through final walkthrough.
Westfield’s Victorian foursquares, Colonial Revivals, and Craftsman bungalows weren’t built to be easy to add onto. Roofline pitches, exterior trim profiles, window proportions — matching these details takes design judgment that has to happen before a permit is pulled, not during framing. A rear addition with the wrong roofline or a second story that ignores the home’s architectural style doesn’t just look wrong. It costs you at resale.
We treat every addition in Westfield as a historic restoration exercise as much as a construction project. Floor plan development and interior space planning start with the existing structure as the guide. Structural coordination, building permits and zoning, and every finish detail are handled under one general contractor with local expertise in what Westfield’s older housing stock requires.
If you have architectural renderings from your architect, we collaborate directly with them through execution. If you’re earlier in the process, Ray can connect you with an architect based on your project and geography. Either way, the goal is a home that looks like it was always meant to be this size.
Building up over the existing footprint creates primary suites, bedrooms, and flexible space on Westfield ranches and Cape Cods where lot coverage limits outward expansion. Requires a full structural assessment before planning begins.
Extending outward from the back preserves curb appeal while opening up family rooms, expanded living areas, and mudroom entries that older floor plans never had.
Most pre-war Westfield homes weren’t built with a primary suite in any modern sense. A dedicated addition — rear or second-story — is consistently one of the highest project-value improvements for homeowners planning to stay long-term.
A proper laundry room, mudroom, or other practical addition built into a larger project scope — plumbing, electrical, and interior space planning handled as part of the build.
On Cape Cods and Colonial Revivals, a well-planned dormer adds head height, daylight, and bedroom count at a lower cost than a full second-story addition — matched to the existing roofline so it looks original.
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 — reducing total cost and scheduling friction compared to managing separate contractors in sequence.
The finish work on a Westfield addition has to hold up against homes built in 1910. Exterior trim matching, custom features, millwork transitions, and interior details that look intentional. Ray is second-generation construction with 40+ years of combined family experience in Northern New Jersey.
Transparent communication about scope, schedule, and cost changes before they happen, not after. On-time delivery is the standard. When something affects the timeline, you hear it from Ray directly.
The structural work, materials, and craftsmanship meet the standard your home demands. Client satisfaction at punch list isn’t the goal — it’s the floor.
Most custom home additions in Westfield run $200–$400 per square foot depending on scope, materials, and type. A rear family room addition might run $100,000–$200,000; a second-story primary suite addition will typically run more. Plan a 10–15% contingency for conditions uncovered during demo — older homes regularly surface aging wiring or original framing that benefits from update while walls are open.
Every Temprano proposal includes clear pricing with every inclusion and exclusion spelled out before you commit. Scope changes are priced and approved before they happen. We offer free, no-obligation estimates.
On financing: additions of this scale are commonly funded through HELOCs or construction loans. Westfield’s property values support the equity access most homeowners need. We don’t offer in-house financing but work regularly with homeowners coordinating bank timing.
Westfield’s housing stock is predominantly pre-1978. EPA certification is legally required for renovation work that disturbs painted surfaces in older homes — Temprano holds both the firm certification and Ray’s individual lead renovator credential.

Yes. All additions require building permits and must meet local zoning requirements. Temprano handles all permit applications. Municipal timelines are outside our control, but we plan around them and keep you informed.
Yes — but it has to be planned that way. Matching roofline pitch, exterior trim, and window proportions on a home with real architectural character has to happen at the design-build stage, not during framing. Ray evaluates these details at the site walk and accounts for them before the proposal is written. If you have architectural renderings, we review them with your architect. If you don’t, Ray can recommend one.
Yes, and it’s often the right call. When walls are open and the crew is on-site, folding in adjacent home renovation — kitchen remodeling, bathroom remodeling, window replacements, or exterior work — costs less and finishes cleaner than managing separate contractors in sequence. We’ll scope it together 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. This is why architects and high-end realtors refer their best clients here.
