1221 Avenue of the Americas vs One Chase Manhattan Plaza Building

1221 Avenue of the Americas
One Chase Manhattan Plaza Building

Comparing the 1221 Avenue of the Americas and the One Chase Manhattan Plaza Building is interesting because they both rise in New York, NY, yet they were conceived by two different design teams, Harrison, Abramovitz & Harris and Skidmore, Owings & Merrill, and were completed at different points in time. They were finished more than a decade apart.

This contrast within the same city allows us to see how different creative minds interpreted the evolving needs of New York across time.

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.

The two towers rely on different structural systems, reflecting distinct engineering strategies.

The 1221 Avenue of the Americas uses a Frame structural system, which relies on a regular grid of columns and beams to sustain its weight, while the One Chase Manhattan Plaza Building uses a Framed Tube In Tube system, that combines a strong central core with a perimeter tube of columns.

Yet, when it comes to their facade, they both employed the same solution, 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.
