One Front Street Building vs One World Trade Center

Comparing the One Front Street Building and the One World Trade Center is compelling because they were both designed by Skidmore, Owings & Merrill, yet they stand in different cities (San Francisco, CA and New York, NY), and were completed over two decades apart.

What this will allow us to see, is how the same firm's approach adapted to different places in different periods of time.

The One World Trade Center is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 1775ft (541m) with 104 floors above ground, while the One Front Street Building reaches 538ft (164m) with 38 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.

The One Front Street Building was designed in the Postmodernism style, while the One World Trade Center reflects the principles of Contemporary.

At the time of their completion, both styles were well established. This makes the comparison especially interesting, because both buildings represent a dominant aesthetic at a particular point in time.

Built 32 years apart (1982 vs 2014), these two buildings are a perfect example of how different architectural styles have shaped the architectural landscape of our cities over time.

Both the One Front Street Building and the One World Trade Center 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 One Front Street Building also provides 290 parking spaces.

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

The One Front Street Building uses a Frame structural system, which relies on a regular grid of columns and beams to sustain its weight, while the One World Trade Center 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.
