Architect and team

Howells & Hood was the architecture firm in charge of the architectural design.

But that's not all, there was also a whole team of architects involved, which included: Reinhard & Hofmeister, and Corbett Harrison & MacMurray.

Howells & Hood was a prominent American architectural firm founded by John Mead Howells and Raymond Hood. The partnership between these two architects left a lasting legacy in the world of skyscraper design during the early 20th century.

Unlike other firms at the time, which would limit their area of influence to a single city or state, Howells & Hood’s buildings can be found in multiple locations, from New York to Chicago.

They are particularly known for their innovative approach to skyscraper design, and their role in this typology progressing from the neogothic and neoclassical to the more modern art-deco style.

Howells Hood

Howells & Hood and the other architects already mentioned were in charge of the architectural design, however, architecture is a complex discipline, which usually involves many professionals from different fields, without whom this building would have not been possible. We will surely be leaving out a lot of names here, but here is a list of the people we do know also played their part in making the 30 Rockefeller Plaza Buiding a reality:

  • Edwards & Hjorth; H.G. Balcom & Associates in charge of Structural Engineering
  • Westinghouse as the company in charge of the elevators system
  • John D. Rockefeller Jr. as the Main Developer
  • Lee Lawrie as the collaborating Artist

Architectural Style

The 30 Rockefeller Plaza Buiding can be categorized as an Art-deco building.

The Art Deco movement flourished during the 1920s and 1930s, with many historians marking the outbreak of World War II as its final decline. Even though a couple of decades might not seem as much, the Art Deco movement had a great impact on architecture, and it's widely represented in many American cities due to the development boom that happened during that time.

Art Deco marked the abandonment of traditional historicism and the embracement of modern living and the age of the machine. In architecture, that meant leaving behind the ornaments of Beux-Arts and Neo-Gothic buildings and instead favoring simplicity and visual impact through geometric shapes, clean lines, and symmetrical designs. Ornaments were still an important part of the design, but they became bold and lavish, and were often inspired by ancient cultures or industrial imagery, instead of nature.

The 30 Rockefeller Plaza Buiding was completed in 1933, right when the Art Deco movement was at its peak, so it kind of went with the trend at that time.

Materials & Structure

The 30 Rockefeller Plaza Buiding uses a frame structure made of steel columns and concrete slabs.

A frame structure uses a combination of beams and columns to sustain the building's weight. The walls in this case are non-load bearing, which allows for more flexibility when distributing the interior spaces.

The facade is non-load bearing either, as it is common in frame structure type buildings.

From an aesthetic point of view, the facade features a Deer Island granite cladding on the first floor, with the rest of the building being cladded with limestone brought from Indiana and prefabricated aluminum parapets.

Other materials found at the 30 Rockefeller Plaza Buiding include, gray marble, used in the lobby walls, bronze, found in moldings walls and rectangular floor patterns, and black terrazo , used for the interior floors.
