900-910 North Lake Shore vs 30 North LaSalle

Comparing the 900-910 North Lake Shore and the 30 North LaSalle is interesting because they both rise in Chicago, IL, yet they were conceived by two different design teams, Mies van der Rohe and Thomas E. Stanley, 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 30 North LaSalle is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 554ft (169m) with 44 floors above ground, while the 900-910 North Lake Shore reaches 0ft (m) with 29 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 900-910 North Lake Shore and the 30 North LaSalle were designed in line with the aesthetic conventions of the International Style style.

The 30 North LaSalle was designed at a moment when the International Style style was already in decline, making it more of a lingering expression of the movement. In contrast, the 900 910 North Lake Shore was built when the style still carried greater cultural weight.

The 900-910 North Lake Shore is primarily residential, while the 30 North LaSalle is primarily commercial.

The 900-910 North Lake Shore offers 524 residential units.

These two towers illustrate the many possible ways to combine structure and enclosure in skyscraper design.
