Home Additions in Riverside, Connecticut
Riverside's shoreline estates and yacht-club properties are built for the water, and the additions homeowners want here open the house to it — a waterfront wing, a great room with walls of glass, or a primary suite with views of the Sound. Because these homes sit on or near the water, the addition has to be coastal-compliant from the foundation up. Omega Development has delivered refined, durable Riverside additions for more than 20 years.
As part of Greenwich, Riverside additions go through the town's rigorous review, and waterfront lots add coastal and, often, Inland Wetlands review on top of Planning & Zoning. We handle the survey, sequence those approvals up front, and design the addition in 3D. One in-house Omega crew then builds it from foundation to finish, keeping the project discreet, clean, and on schedule.
What to know about a home addition in Riverside
A waterfront addition sits in a coastal flood zone, which shapes everything below the finishes — elevation requirements, flood-resistant construction, and corrosion- and salt-air-resistant materials designed to last on the shoreline. Setbacks, coverage, and FAR still govern the size, and coastal and P&Z review can drive the timeline as much as the build, so we sequence approvals before design is locked.
The additions we do most here are waterfront wings and great rooms that capture the view, along with primary suites. Cost is driven by the coastal foundation, the level of stone and custom millwork, size, and finishes — a wing or great-room addition on Riverside's waterfront commonly runs in the mid-to-high six figures, all itemized before work begins.
Waterfront additions built for the Sound
We build the waterfront wings and great rooms Riverside's shoreline homes are made for — elevated, coastal-grade foundations, salt-air-resistant materials, and walls of glass to the water — navigated cleanly through Greenwich's coastal and P&Z review.

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.
