7 World Trade Center vs 1540 Broadway Building

7 World Trade Center
1540 Broadway Building

Comparing the 7 World Trade Center and the 1540 Broadway Building is particularly interesting because they share the same skyline in New York, NY, and were both designed by Skidmore, Owings & Merrill. However, they were completed more than 16 years apart.

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

The 7 World Trade Center is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 741ft (226m) with 51 floors above ground, while the 1540 Broadway Building reaches 617ft (188m) with 42 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.

Structure & Facade

Structure
Frame
Facade
Curtain Wall

Both the 7 World Trade Center and the 1540 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.
