New Home Construction in Greenwich, Connecticut
Building a new home in Greenwich means building to the highest bar in Connecticut. From Back Country's multi-acre parcels to Riverside's waterfront and Glenville's established neighborhoods, a new build here is expected to be estate-grade in craft and flawless in its approvals. Omega Development is a licensed Connecticut New Home Construction contractor (NHC #0017262) with more than 20 years delivering the kind of precision high-end Greenwich construction demands.
Greenwich review is often as much of the project as the build itself. Beyond a building permit, a new home can trigger Planning & Zoning and Inland Wetlands (IWWA) review, and Back Country's large lots frequently follow a longer approval track. One in-house Omega crew handles the build across every trade, and every home is designed in 3D — stone, millwork, massing, and finishes — before demo or excavation begins.
What to know about building a new home in Greenwich
Zoning drives everything in Greenwich. FAR, lot coverage, setbacks, and height limits vary sharply between a Back Country RA-4 lot and a tighter Glenville or Riverside parcel, and P&Z sets the buildable envelope before design is final. Where a lot touches a watercourse, wetland, or the shoreline, Inland Wetlands and coastal (CAM) review add their own steps — we sequence all of it up front so approvals don't stall the build.
Estate construction in Greenwich also means the substance behind the finish: deep foundations, natural-stone facades, extensive millwork, whole-house mechanical and generator systems, and pool and site work coordinated with the house. We design stone-manor and classically detailed homes to suit the setting, and manage the full permitting, P&Z, and IWWA process with the discretion Greenwich homeowners expect.
Estate homes, Greenwich-grade approvals
A Greenwich new build lives or dies on navigating the town's rigorous review — P&Z, Inland Wetlands, and the longer approval track that Back Country's large lots often require. We handle that process cleanly while building estate-grade stone-manor homes, so the finished residence matches both the land and the standard Greenwich holds it to.

It was a pleasure working with Inacio and the Omega team! My home renovation project was not an easy or simple one, with many challenges along the way, as most construction projects tend to be. Inacio was able to navigate his way through the tough times and find solutions, ultimately leading to a stellar finished product, far exceeding expectations. What's also nice is that we've developed and continue to maintain a strong relationship even to this day. Inacio is a great person and a solid resource to have.

Inacio and his team at Omega built a stunning three-season porch for my family. There aren't enough words to say how impressed we were with his honesty, integrity, and craftsmanship. Inacio was always available and frequently came to check on the work. His team is professional and meticulous — especially the finish carpentry guys, amazing! When an issue came up, Inacio fixed it, no questions asked — truly a man of his word. I will never use anyone else. I HIGHLY recommend him!

Omega Development renovated my home's living room, hallway, two full bathrooms, and a half powder room after a water leak from the second-floor bathroom. I was amazed by Omega crew's craftsmanship and detail-oriented finishes — the work really came out great. I fully recommend them.

Omega did two jobs for us and we are so pleased with the results. They have skilled workers who complete whatever you ask while keeping the rest of the home and their work area as clean as possible. They replaced sheet rock and repainted a ceiling in one room, then did a tile demo and wall/tile install in another bathroom. Very timely — they'd arrive early to get started as soon as they could.

Fantastic experience with Omega on the renovation of my home. Inacio and his team were always there, over-communicating, and the end results are extremely high quality. It's hard to find honest, high-quality contractors today, and I'm delighted to have hired Inacio and his team — I'd recommend them highly to anyone.

The best! I cannot recommend Inacio, Rafa, and their entire team more highly. Omega Development executed a major home renovation for my family — extending our living room, a full kitchen reno, and an additional master bedroom and bath.

I recently had my kitchen and bathroom renovated and my bar area completely redone by Omega Development, and I couldn't be happier with the results. From start to finish, their team provided top-notch service.

We have used Omega for all our needs these past few years. That has included everything from minor repairs, a full house painting (inside and out), and floor refinishing, to an addition on the third floor.
