55 East Erie Street Building vs St. Regis Chicago

Comparing the 55 East Erie Street Building and the St. Regis Chicago is interesting because they both rise in Chicago, IL, yet they were conceived by two different design teams, Fujikawa Johnson & Associates and Studio Gang Architects, 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 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 55 East Erie Street Building reaches 647ft (197.2m) with 56 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 1,126,001 sqf (104,609m²) more than what the 55 East Erie Street Building 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 55 East Erie Street Building 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 Fujikawa Johnson & Associates 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.

Both the 55 East Erie Street Building and the St. Regis Chicago were designed to serve as residential towers, and that has remained their main use since their completion, serving similar roles in the urban fabric.

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

In terms of capacity, the 55 East Erie Street Building offers 194 apartments, while the St. Regis Chicago provides 393 units.

Both towers provide significant parking capacity, with 55 East Erie Street Building offering 425 spaces and the St. Regis Chicago offering 295.

Both towers share the same structural solution, a Frame 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.

However, when it comes to the facade, both buildings use different approaches. The 55 East Erie Street Building uses a Modular facade, while the St. Regis Chicago uses a Curtain Wall facade.

A Modular facade like the one seen in the 55 East Erie Street Building employs prefabricated panels, often mixing solid surfaces with smaller windows, while a curtain-wall facade like the one seen in the St. Regis Chicago uses a lightweight glass curtain wall hung from the structure.
