340 on the Park Building vs One Chicago East Tower

Comparing the 340 on the Park 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, Solomon Cordwell Buenz 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 340 on the Park Building reaches 672ft (204.8m) with 62 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 340 on the Park 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 Solomon Cordwell Buenz 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.

Both the 340 on the Park Building and the One Chicago East Tower were designed to serve as residential towers, and that has remained their main use since their completion, serving similar roles in the urban fabric.

In terms of capacity, the 340 on the Park Building offers 344 apartments, while the One Chicago East Tower provides 353 units.

Both towers provide significant parking capacity, with 340 on the Park Building offering 468 spaces and the One Chicago East Tower offering 1100.

Both the 340 on the Park Building and the One Chicago East Tower 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.
