900-910 North Lake Shore vs 330 N. Wabash Avenue Building

Comparing the 900-910 North Lake Shore and the 330 N. Wabash Avenue Building is particularly interesting because they share the same skyline in Chicago, IL, and were both designed by Mies van der Rohe. However, they were completed more than 16 years apart.

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

The 330 N. Wabash Avenue Building is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 669ft (204m) with 52 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 330 N. Wabash Avenue Building were designed in line with the aesthetic conventions of the International Style style.

The 330 N. Wabash Avenue Building 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 330 N. Wabash Avenue Building is primarily commercial.

The 330 N. Wabash Avenue Building incorporates a 5-star hotel with 316 rooms.

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

Both the 900-910 North Lake Shore and the 330 N. Wabash Avenue Building 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.
