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 more than almost any other project, so an honest answer starts with what you're actually building. A small bump-out that extends an existing room is a very different job from a full second-story addition that touches the roof, the foundation load, and sometimes the mechanical systems for the whole house. Type drives the number: a ground-floor family-room addition, a primary-suite addition, a garage conversion, and a second story each carry their own structural and finish costs. Size and finish level then move it up or down from there. Because the range is so wide, we don't throw out a per-square-foot figure that could mislead you. Instead, we visit, look at what's structurally and practically feasible for your home and lot, factor in zoning and setbacks, and give you a clear written quote with a realistic range for your specific project — so the number you're planning around reflects your house, not a generic average.
How long does an addition take? +
Most additions run about two to four months of active construction, and it's important to plan for design and permitting time before that clock even starts. An addition is essentially building a small house attached to your existing one, so the up-front phase — architectural design, structural engineering, zoning review, and permit approval — can take several weeks to a few months depending on your town and whether any variances are needed. Once permits are in hand, construction moves through foundation, framing, roofing, exterior tie-in, mechanicals, insulation, and interior finish, each in sequence. A simple bump-out finishes faster; a second story or a large primary-suite addition takes longer, especially when weather affects the exterior phases. We map all of this out and give you a realistic schedule with your quote, including the design and permitting runway, so you have a true end-to-end timeline rather than just the construction window — and we keep you updated against it throughout.
Do you handle design, engineering, and permits? +
Yes — and having it all under one roof is one of the biggest advantages of working with us on an addition. We manage the architectural design, structural engineering, zoning review, permitting, and inspections as one coordinated process, so you're not stuck acting as the go-between for an architect, an engineer, the town, and a builder who all point at each other when something doesn't line up. We start with design that fits your home and your budget, bring in structural engineering to make sure the new load is carried properly and the existing structure can support it, and handle the zoning and setback questions that decide what's actually allowed on your lot. Then we pull the permits and schedule the inspections at each phase. Coordinating these pieces ourselves keeps the project moving, prevents the costly gaps that happen when trades work from mismatched plans, and gives you a single point of accountability from the first sketch to the final sign-off.
Will the addition match the rest of my house? +
That's the goal on every addition — when it's done right, no one should be able to tell where the original house ends and the new space begins. Achieving that takes deliberate attention to the details that give an addition away when they're ignored. We match rooflines and pitches so the new roof reads as part of the original silhouette, blend siding and match trim profiles so the exterior is seamless, and carry interior floor heights through so you're not stepping up or down into the new room. We also pay attention to window styles, fascia and soffit details, and how the addition ties into the existing structure. On older North Jersey homes, that sometimes means sourcing materials to match what's no longer standard off the shelf. The result is a space that looks like it was always part of the house — adding room and value — rather than an obvious bolt-on that dates the home and works against you at resale.
Can we stay in the house during construction? +
Usually, yes — most families stay in their home throughout an addition, and we plan the project specifically to make that possible. Because an addition is largely built onto or alongside your existing structure, we can seal off the work area with dust barriers, keep the construction traffic and debris contained to that zone, and leave the rest of your home clean and livable. The one genuinely disruptive moment is the tie-in, when we connect the new space to the existing house by opening up a wall or roof section. We sequence that carefully — getting the new structure weather-tight first — so the opening is brief and controlled rather than leaving your home exposed. There are exceptions: some projects, like certain second-story additions or work that takes your only kitchen or bathroom offline for an extended stretch, can make staying impractical. If yours is one of those, we'll tell you honestly and up front so you can plan, rather than discovering it mid-build.
Are you licensed and insured? +
Yes. Hamlett Renovations is a licensed New Jersey Home Improvement Contractor, NJ HIC #13VH12093400, and fully insured, and every addition we build is backed by a 1-year workmanship warranty. An addition is one of the largest investments a homeowner makes, and it involves structural work that affects the safety and value of your entire house — which is exactly why hiring a properly licensed and insured contractor matters here more than on almost any other project. New Jersey requires home improvement contractors to register with the state, and we'll gladly provide proof of insurance before you sign. Because an addition changes the structure of your home, the design and engineering are permitted and inspected at every phase, giving you an independent record that the work was done to code. The workmanship warranty then stands behind our construction for a full year, so if anything we built isn't performing the way it should, we come back and make it right.
