Expert Contractors
Pro Build Restoration specializes in building additions throughout New York City and Long Island. Whether you need to add a floor to an existing building, expand horizontally, build a rooftop addition, or construct an accessory structure, our experienced team manages the entire process from structural design coordination through DOB sign-off.
Building additions in NYC require extensive DOB permitting, zoning analysis, structural engineering, and careful construction sequencing. We have the experience to navigate this complex process and deliver code-compliant additions that maximize your property value.
What We Do
Our Work
How It Works
We analyze NYC zoning (or Nassau/Suffolk zoning) to determine what additions are allowable under as-of-right development rights and FAR.
We coordinate with licensed structural engineers and architects to develop DOB-approvable drawings for the addition scope.
Full DOB Alteration permit application including structural drawings, energy compliance, and all required approvals.
We prepare the existing building for the addition — reinforcing foundations, installing temporary shoring, and making all connections.
Framing, structure, roofing, windows, MEP rough-in, insulation, and exterior work are completed per the approved plans.
Interior finishes, DOB inspections, and Certificate of Occupancy are completed — delivering a fully legal, added space.
