200 Vesey Street Building vs Key Tower

Comparing the 200 Vesey Street Building and the Key Tower is an interesting exercise, because even though they are located in different cities (New York, NY and Cleveland, OH), both were designed by Cesar Pelli & Associates and finished within within 5 years of each other. This gives us the chance to see how the same architect's ideas were expressed in different urban contexts almost simultaneously.

The Key Tower is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 948ft (289m) with 62 floors above ground, while the 200 Vesey Street Building reaches 0ft (m) with 51 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 Vesey Street Building and the Key Tower were designed in line with the aesthetic conventions of the Postmodernism style.

The Key Tower was designed at a moment when the Postmodernism style was already in decline, making it more of a lingering expression of the movement. In contrast, the 200 Vesey Street Building was built when the style still carried greater cultural weight.

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

The 200 Vesey Street Building also provides 800 parking spaces.

Both towers share the same structural solution, a Frame 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.

However, when it comes to the facade, both buildings use different approaches. The 200 Vesey Street Building uses a Curtain Wall facade, while the Key Tower uses a Modular facade.

A Curtain Wall facade like the one seen in the 200 Vesey Street Building uses a lightweight glass curtain wall hung from the structure, while a modular facade like the one seen in the Key Tower employs prefabricated panels, often mixing solid surfaces with smaller windows.
