Michigan Plaza South vs 55 East Erie Street Building

Comparing the Michigan Plaza South and the 55 East Erie Street Building is particularly interesting because they share the same skyline in Chicago, IL, and were both designed by Fujikawa Johnson & Associates. However, they were completed more than 19 years apart.

This offers a unique perspective on how the architect's style and the city's architecture evolved over time.

The 55 East Erie Street Building is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 647ft (197.2m) with 56 floors above ground, while the Michigan Plaza South reaches 554ft (169m) with 44 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 Michigan Plaza South was designed in the International Style style, while the 55 East Erie Street Building reflects the principles of Contemporary.

The Michigan Plaza South represents a late expression of the International Style, a style already in decline in 1985 when it was completed. By contrast, the 55 East Erie Street Building followed the then mainstream Contemporary, embodying the dominant architectural direction of its time.

The Michigan Plaza South is primarily commercial, while the 55 East Erie Street Building is primarily residential.

The 55 East Erie Street Building offers 194 residential units.

The 55 East Erie Street Building also provides 425 parking spaces.

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 Michigan Plaza South uses a Curtain Wall facade, while the 55 East Erie Street Building uses a Modular facade.

A Curtain Wall facade like the one seen in the Michigan Plaza South uses a lightweight glass curtain wall hung from the structure, while a modular facade like the one seen in the 55 East Erie Street Building employs prefabricated panels, often mixing solid surfaces with smaller windows.
