Palmolive Building vs Chicago Board of Trade Building

Comparing the Palmolive Building and the Chicago Board of Trade Building is particularly interesting because they share the same skyline in Chicago, IL, and were both designed by Holabird & Root. However, they were completed more than 10 years apart.

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

The Chicago Board of Trade Building is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 604ft (184m) with 44 floors above ground, while the Palmolive Building reaches 564ft (172m) with 37 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 Palmolive Building and the Chicago Board of Trade Building were designed in line with the aesthetic conventions of the Art Deco style.

The Chicago Board of Trade Building was designed at a moment when the Art Deco style was already in decline, making it more of a lingering expression of the movement. In contrast, the Palmolive Building was built when the style still carried greater cultural weight.

The Palmolive Building is primarily residential, while the Chicago Board of Trade Building is primarily commercial.

Originally, the Palmolive Building was designed for commercial, but over time it was converted to residential. The Chicago Board of Trade Building by contrast has maintained its original role.

The Palmolive Building offers 102 residential units.

Both the Palmolive Building and the Chicago Board of Trade 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 Masonry facade.

A masonry facade gives the building a heavier, more traditional appearance. It often conceals a frame structure behind it, creating the look of solid walls without carrying the main loads.
