Rockefeller Center Overview

Master Plan and Exterior Rehabilitations

National Trust for Historic Preservation Honor Award

Developed for the purpose of planning maintenance and capital improvement projects, Hoffmann Architects’ Exterior Rehabilitation Master Plan for Rockefeller Center encompassed the nineteen buildings of John D. Rockefeller Jr.’s 22-acre “city within a city.” The buildings are subject not only to New York City Department of Buildings regulations, including New York City Local Law 10 of 1980 and Local Law 11 of 1998 (LL10/LL11), but also to Landmark Commission restrictions, making rehabilitation planning particularly challenging. Hoffmann Architects’ Master Plan addressed these considerations, while achieving even budgeting across the years. The award-winning rehabilitation program included facade and curtain wall restoration, roof replacements, waterproofing, and historic preservation for this National Historic Landmark and centerpiece of New York City.

In conjunction with the Master Plan, Hoffmann Architects developed specific rehabilitation solutions for the Center’s structures, including:
