Designed as a city within a city, Merchandise Mart is an iconic presence – and our business center gives you the chance to get a world-class presence of your own. On the 12th floor of what was once the largest building in the world, our center has everything you need to do business in comfort and style. Meanwhile, lower floors offer a luxury retail and wholesale experience, as well as offices for companies from industries including advertising, technology, and more. So whether you’re working or networking, making calls or making new connections, you never need to leave. It’s enough to make you forget that there’s another city – and a balanced, busy economy - right outside the door. But from Merchandise Mart’s own subway station, you’ll have great access to The Loop, Chicago’s central business district (CBD) and the wider city.
