Chicago Board of Trade Building vs Carbide & Carbon Building

Comparing the Chicago Board of Trade Building and the Carbide & Carbon Building is interesting because they both rise in Chicago, IL, yet they were conceived by two different design teams, Holabird & Root and Burnham Brothers, 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!

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 Chicago Board of Trade Building and the Carbide & Carbon 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.
