Salesforce Tower vs St. Regis Chicago

Comparing the Salesforce Tower and the St. Regis Chicago is interesting because they both stand in Chicago, IL, and were completed within 2 years of each other, but they were designed by different architects.

This offers a unique glimpse at how rival designers approached projects in the same city during the same era.

The St. Regis Chicago is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 1194ft (364m) with 101 floors above ground, while the Salesforce Tower reaches 817ft (249m) with 57 floors above ground.

St. Regis Chicago also offers more total built-up area, a total fo 1,900,001 sqf (176,516m²), which is about 450,006 sqf (41,807m²) more than what the Salesforce Tower offers.

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 Salesforce Tower and the St. Regis Chicago 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 Pelli Clark & Partners and Studio Gang Architects followed what was in many ways expected of them, producing designs that fit comfortably within contemporary architectural norms, rather than breaking with convention.

The Salesforce Tower is primarily commercial, while the St. Regis Chicago is primarily residential.

The St. Regis Chicago incorporates a 5-star hotel with 192 rooms. More information is available at the official website.

The St. Regis Chicago offers 393 residential units.

The St. Regis Chicago also provides 295 parking spaces.

Both the Salesforce Tower and the St. Regis Chicago 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.
