Home Extensions · Nassau County, NY
When you love your neighborhood but need more space, an addition is the answer. We design extensions that add real, livable square footage and blend so seamlessly you'd never know where the old house ends.
Premier Extensions
The difference between a good addition and a great one is how well it disappears. We match rooflines, siding, trim and proportions to the existing home so your extension reads as original architecture — not a bolt-on.
From a bigger kitchen and family room to a first-floor primary suite or a full in-law setup, we handle the structural engineering, the Town of Hempstead permits, and the construction as one team.
Start Your Project →How We Work
A seamless experience from first sketch to the final reveal.
We meet in your home, listen to how you live, and take detailed measurements of the existing space.
You see your project in realistic 3D and refine the layout, finishes and materials with our designer.
We guide every material selection and handle the permits and documentation the town requires.
Our own craftsmen execute the work cleanly, on schedule, protecting your home throughout.

Kind Words
"They took our dated space down to the studs and gave us something out of a magazine. Clean, on time, and genuinely cared about the details."
"From the 3D design to the final walk-through, everything was exactly as promised. It made a full renovation feel completely manageable."
"Craftsmanship you can feel. Flawless work, done on the schedule they gave us up front. We've already recommended them to neighbors."

Good to Know
Yes, and we handle all of it — architectural drawings, structural engineering and the Town of Hempstead permit process are part of our scope.
In most cases, yes. We phase the work and seal off the construction zone so your family can live at home through the project.
Timelines vary with size and approvals, but most additions run three to six months from permit to completion. We give you a schedule up front.
That's the whole point. We match rooflines, siding, windows and trim so the new space looks original to the home.
