1185 Avenue of the Americas Building vs 1585 Broadway Building

Comparing the 1185 Avenue of the Americas Building and the 1585 Broadway Building is particularly interesting because they share the same skyline in New York, NY, and were both designed by Emery Roth & Sons. However, they were completed more than 19 years apart.

This offers a unique perspective on how the architect's style and the city's architecture evolved over time.

The 1185 Avenue of the Americas Building was designed in the International Style style, while the 1585 Broadway Building reflects the principles of Postmodernism.

The 1185 Avenue of the Americas Building represents a late expression of the International Style, a style already in decline in 1971 when it was completed. By contrast, the 1585 Broadway Building followed the then mainstream Postmodernism, embodying the dominant architectural direction of its time.

Both the 1185 Avenue of the Americas Building and the 1585 Broadway 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 the 1185 Avenue of the Americas Building and the 1585 Broadway 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.
