Chicago has earned its place on the architectural map with endless distinctions, including being home to the tallest building in the world for 25 years and to numerous acclaimed architects like Mies van der Rohe, Frank Lloyd Wright, Marion Mahony Griffin and Jeanne Gang. But did you know that it’s also home to the world’s largest commercial building? Today, we’re taking a look at the history of the city’s beloved Merchandise Mart.

How It Came to Be

As dated infrastructure (like the abandoned railroad yards in the downtown area) proliferated in the early decades of the 20th century, more and more land development opportunities opened up. In hopes of beautifying the frontage along the Chicago River, Marshall Field & Co. announced their purchase of one of the largest available sites, at the junction of the River’s branches. The company began construction in 1928 and when the Merchandise Mart opened in 1930, it achieved the company’s dream of becoming a dedicated wholesale center for architectural and interior design vendors and trades serving the entire nation. And, with 4 million square feet on 25 floors under a single roof spanning two city blocks, it became the largest building in the world.

TheMART was imagined as a city-within-a-city. Graham, Anderson, Probst & White, the architects behind the structure’s streamlined look, took inspiration from traditional Art Deco architectural elements, including ribbon piers to define windows, setbacks and pavilions atop each corner to disguise the bulk of the building. Marshall Field himself was involved in the building’s design; his love for art inspired him to employ Jules Guerin to create 17 murals on the interior lobby’s frieze. Each mural details trade throughout the world and depicts the products, transportation and architecture of 14 countries.

TheMART was also a monumental experiment in state-of-the-art engineering and modern materials. At a cost of $26 million, it took advantage of construction techniques normally used in the building of big dams and employed nearly 5,700 workers at the height of the Great Depression.

theMART in the Modern Era

Throughout the latter half of the 20th century, theMART faced a handful of modernization projects. One was designed by Helmut Jahn to connect the building with the Apparel Center located across Orleans Street with a pedestrian bridge. The building was LEED Certified Silver in 2007, followed by LEED Gold Certification in 2013 and in 2018.

In recent years, as the contract furniture industry has evolved from a focus on a wholesale hub and independent manufacturer showrooms, the Mart has repositioned itself as a destination for innovation, creativity, technology and entrepreneurship. Rebranded “theMART,” the building remains the world’s largest commercial building, and has become home to a host of changemakers, including Motorola Mobility, 1871, Yelp, PayPal and MATTER, as well as Fortune 500 companies Conagra, Allstate, Kellogg, Beam Suntory, and Grainger.

Today, theMART continues to celebrate an appreciation for architecture and art. The building now hosts a digital art display popularly known for “Art on theMART,” to showcase the work of prominent artists on the south façade of the structure.
