General Contractor — The Hamptons

Rosembarg Construction has been delivering luxury residential renovations in the Hamptons for years. From East Hampton to Southampton, we understand the standard that Hamptons properties demand — and we build to it.

Whether you're renovating a primary residence or a seasonal home, the level of finish and attention to detail is the same. We coordinate trades, manage timelines, and maintain clear communication throughout — so you're never left wondering where your project stands.

Our completed East Hampton renovation — featuring a custom library, three fully renovated bathrooms, a redesigned kitchen, and bespoke finish work throughout — is representative of what we deliver in the area.

If you're planning a renovation in the Hamptons, we work with a select number of projects at a time to ensure every job receives the oversight it deserves.
