Chicago Board of Trade Building vs LaSalle-Wacker Building

Chicago Board of Trade Building
LaSalle-Wacker Building

Comparing the Chicago Board of Trade Building and the LaSalle-Wacker 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 9 years apart.

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

Structure & Facade

Masonry

Both the Chicago Board of Trade Building and the LaSalle-Wacker 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.
