More space without leaving the home you love. Shed and gable dormers, second-story additions, and full home extensions designed and built for Nassau and Suffolk County homeowners.
Outgrowing your home doesn't have to mean leaving it. A well-built dormer or extension can add the bedroom, the bathroom, the home office, or the master suite you've been priced out of — without the cost, stress, or upheaval of moving.
For two decades we've helped Long Island families turn cramped Capes, ranches, and split-levels into the homes they were always meant to be. Every project starts with a real conversation about how you live now and how you want to live next.
Cape Cods, ranches, colonials, and split-levels all benefit from different dormer styles. We'll help you choose the one that adds the most usable space while complementing the home you have.
A single sloped roof extending from the main roofline. Adds the most usable square footage and is the most popular choice for Cape Cods.
A peaked, triangular dormer ideal for adding light and architectural character. Best for traditional and colonial-style homes.
Runs the full length of the home — effectively a full second story. The right call when you need a whole new floor of living space.
Specialty dormers for character and curb appeal. Less square footage gained — but a beautiful upgrade for the right home.
If you've maxed out your footprint or you love your lot, a second-story addition is often the smartest way to nearly double your square footage. We handle every step — from architectural plans and engineering to permits, framing, and final interior finishing.
Rear, side, and wrap-around home extensions are the cleanest way to get the kitchen, family room, master suite, or in-law setup you've been picturing. We handle small bump-outs and full multi-room additions across Long Island — every one designed to look like it was always part of the house.
Adding to a home is more complex than building from scratch. Our process is designed to minimize surprises, protect your existing home, and keep you in it whenever possible.
We tour your home, talk through what's missing, and assess what's structurally possible.
Architectural drawings, structural engineering, and a fixed-price quote — all before you commit.
We file every permit and coordinate with your town's building department from start to finish.
Demo, framing, weather-tight enclosure, then mechanicals and finishing — all by our crew.
Most dormer projects on Long Island fall between $80,000 and $250,000+ depending on size, style (gable vs. full shed), level of interior finishing, and your existing roof structure. Full second-story additions typically run $200,000–$500,000+. We provide detailed, itemized estimates with no surprise add-ons.
Usually no. For dormers and most extensions, we work to keep your home livable throughout. We tarp and weather-protect each day, install temporary plumbing/electrical where needed, and schedule the more disruptive work in tight phases. For full second-story additions, there may be a short period where temporary housing is more comfortable — we'll be upfront about that during planning.
A standard dormer typically takes 8–14 weeks from groundbreaking to final inspection. Full second-story additions and large home extensions usually run 4–8 months. Permit timelines vary by town — we factor realistic estimates into every schedule.
Most homeowners on Long Island will need an up-to-date survey, and some projects may require a variance depending on lot lines, setbacks, or zoning. We'll identify these needs in our initial visit and coordinate with surveyors and architects as needed.
Yes — and we insist on it. A well-built dormer or extension should look like it was always there. We match rooflines, siding profiles, window styles, and trim details so the finished home reads as a single, cohesive design.
Call us directly. We'll come to your home, walk the project, and put together a detailed plan and fixed-price quote.
