200 Liberty Street Building vs 225 Liberty Street Building

Comparing the 200 Liberty Street Building and the 225 Liberty Street Building is especially interesting because they share much in common. Both rise in New York, NY both were designed by Cesar Pelli & Associates, and they were completed just one year apart.

This overlap gives us a unique opportunity to understand how Cesar Pelli & Associates approached different commissions in the same urban context and historical context during a short period.

The 225 Liberty Street Building is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 646ft (197m) with 44 floors above ground, while the 200 Liberty Street Building reaches 577ft (176m) with 40 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 200 Liberty Street Building and the 225 Liberty Street Building were designed in line with the aesthetic conventions of the Postmodernism style.

At the time, this style was at the height of its popularity. So Cesar Pelli & Associates followed what was in many ways expected at the time, producing designs that fit comfortably within contemporary architectural norms rather, than breaking with convention.

Both the 200 Liberty Street Building and the 225 Liberty Street Building were designed to serve as commercial towers, and that has remained their main use since their completion, serving similar roles in the urban fabric.

Both towers provide significant parking capacity, with 200 Liberty Street Building offering 232 spaces and the 225 Liberty Street Building offering 800.

Both the 200 Liberty Street Building and the 225 Liberty Street Building rely on a Frame structural system.

A frame structure uses a grid of columns and beams to carry the building's loads. This frees the walls from structural duties, allowing for flexible floor plans and larger windows.

They also employ the same type of facade, a Curtain Wall facade.

A curtain wall is a non-load-bearing facade hung from the structural frame. It is anchored to floor slabs and transfers only its own weight and wind loads, allowing for sleek, glassy exteriors.
