North Harbor Tower vs Michigan Plaza North

North Harbor Tower
Michigan Plaza North

Comparing the North Harbor Tower and the Michigan Plaza North 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 7 years apart.

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

The North Harbor Tower is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 554ft (169m) with 55 floors above ground, while the Michigan Plaza North reaches 335ft (102m) with 25 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 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 North Harbor Tower uses a Window Wall facade, while the Michigan Plaza North uses a Curtain Wall facade.

A Window Wall facade like the one seen in the North Harbor Tower uses panels fitted between floor slabs, leaving slab edges visible, while a curtain-wall facade like the one seen in the Michigan Plaza North uses a lightweight glass curtain wall hung from the structure.
