A New York–based luxury general contractor delivering high-end residential renovations and select retail environments — built to the standard your project demands.
Rosembarg Construction is a New York–based luxury general contractor specializing in high-end residential renovations across Manhattan, Long Island, and the Hamptons.
We work alongside interior designers, architects, and discerning homeowners to deliver spaces that are precise, refined, and built to last.
Our approach →Logos represent companies where Rosembarg has completed past projects. All trademarks are property of their respective owners; inclusion is for portfolio purposes only and does not imply sponsorship, endorsement, or ongoing partnership.
We build backward from the final detail — aligning framework, millwork, and materials to achieve a refined result.
Structured coordination, realistic timelines, and direct communication from the first walkthrough to the final punch list.
Quality is not an upgrade at Rosembarg. It is the baseline every project starts from.
We review scope, constraints, building requirements, and overall vision — establishing clear parameters before pricing begins.
Detailed estimates are developed around materials, labor sequencing, and logistical considerations — minimizing surprises later.
Site management, trade coordination, and quality control executed with consistent oversight to ensure finish exceeds expectations.
Final walkthrough, punch-list, documentation, and long-term support conclude the project.
Your reputation is on the line every time you refer a contractor. We protect it — reading the spec sheet, coordinating your vendors, and flagging problems before they become yours. One point of contact, full accountability, publication-level finish.

Rosembarg Construction renovated the interior of my home, and the entire process was smooth from start to finish. Bryan and Michael were professional, easy to communicate with, and very detail-oriented. The finished work came out clean and high quality. Would definitely use them again and highly recommend them to anyone looking for a reliable contractor.
