— 2.5 Million-Square-Foot Class-A Office Building in Midtown Manhattan

The 2.5 million-square-foot McGraw-Hill Building soars 670 feet in Rockefeller Center at the western boundary adjoining the Times Square district. The 52-story building was a monument to quality when it first opened in 1972, and it has been maintained meticulously ever since. In the most recent years it has undergone extensive renovation, modernization, and enhancement.

The McGraw-Hill Building is one of three adjacent towers Rockefeller Group Development Corporation completed in the early 1970s in a major expansion of Rockefeller Center. Combined with the adjoining Time & Life Building, opened a decade earlier, and with 745 Seventh Avenue, opened in 2001, the newer towers more than doubled Rockefeller Center’s total rentable floor space.

Following a quarter century of full occupancy and successful operation, the McGraw-Hill Building’s extensive renovation was prompted by a fortunate confluence of rising tenant needs, advancing technology, and normal equipment life cycles.

Today the McGraw-Hill Building embodies the freshest examples of the ideas that first drew the world’s admiration to Rockefeller Center in the 1930s — numerous artworks and welcoming public plazas; bold, confident design; the most sophisticated operations and amenities; the highest standards for business environments.

The McGraw-Hill Companies, the anchor tenant and equity partner when The Rockefeller Group developed the building, has renewed its tenancy and partnership far into the 21st century. A stunning new lobby and entrance are the most outward among many signs affirming the McGraw-Hill Building’s sustained leadership in the future.
