30 Rockefeller Plaza Buiding vs 20 Exchange Place Building

Comparing the 30 Rockefeller Plaza Buiding and the 20 Exchange Place Building is interesting because they both stand in New York, NY, and were completed within 2 years of each other, but they were designed by different architects.

This offers a unique glimpse at how rival designers approached projects in the same city during the same era.

The 30 Rockefeller Plaza Buiding is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 853ft (260m) with 70 floors above ground, while the 20 Exchange Place Building reaches 774ft (236m) with 57 floors above ground.

Of course, each project may have faced different briefs or regulatory constraints, which we don't really know about and could also explain the outcome.

Both the 30 Rockefeller Plaza Buiding and the 20 Exchange Place Building were designed in line with the aesthetic conventions of the Art Deco style.

At the time, this style was at the height of its popularity. So both Howells & Hood and Cross & Cross followed what was in many ways expected of them, producing designs that fit comfortably within contemporary architectural norms, rather than breaking with convention.

The 30 Rockefeller Plaza Buiding is primarily commercial, while the 20 Exchange Place Building is primarily residential.

Originally, the 20 Exchange Place Building was designed for commercial, but over time it was converted to residential. The 30 Rockefeller Plaza Buiding by contrast has maintained its original role.

The 20 Exchange Place Building offers 762 residential units.

These two towers illustrate the many possible ways to combine structure and enclosure in skyscraper design.
