300 North LaSalle Building vs One Chicago East Tower

Comparing the 300 North LaSalle Building and the One Chicago East Tower is interesting because they both rise in Chicago, IL, yet they were conceived by two different design teams, Pickard Chilton and Goettsch Partners , 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 Chicago across time.

Let's take a closer look!

The One Chicago East Tower is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 971ft (296m) with 77 floors above ground, while the 300 North LaSalle Building reaches 784ft (239m) with 57 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 300 North LaSalle Building and the One Chicago East Tower were designed in line with the aesthetic conventions of the Contemporary style.

At the time, this style was at the height of its popularity. So both Pickard Chilton and Goettsch Partners followed what was in many ways expected of them, producing designs that fit comfortably within contemporary architectural norms, rather than breaking with convention.

The 300 North LaSalle Building is primarily commercial, while the One Chicago East Tower is primarily residential.

The One Chicago East Tower offers 353 residential units.

Both towers provide significant parking capacity, with 300 North LaSalle Building offering 225 spaces and the One Chicago East Tower offering 1100.

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

The 300 North LaSalle Building uses a Framed Tube In Tube structural system, which combines a strong central core with a perimeter tube of columns, while the One Chicago East Tower uses a Frame system, that relies on a regular grid of columns and beams to sustain its weight.

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.
