A Historic Loop Office Tower With a Tenant-Only Rooftop

Look up at 1 North Dearborn for the commercial side of the Loop. This historic commercial office building rises to a height of 17 stories, putting its scale at the center of an architecture focused stop in downtown Chicago. Nearly a million square feet of workspace occupy the building, a reminder that this is a working address.

Open floorplates and high ceilings shape the interiors, with sweeping city views adding another dimension to the working day. The rooftop amenities pair a park with a penthouse lounge, and both are reserved for tenants only.

Below the office floors, a gym in the basement adds another amenity to the workplace. At 1 N Dearborn St, the building opens Monday through Friday from 9 AM to 5 PM and is closed Saturday and Sunday. Make the exterior your focus when passing through on an architecture wander.
