The Chicago Tribune reports the Sears Tower will change its name to Willis Tower under the terms of a new lease signed by global insurance broker Willis Group Holdings.

Willis Group plans to consolidate five area offices and move nearly 500 Associates into Willis Tower, initially occupying more than 140,000 square feet on multiple floors.

Willis said its move to the new space, at $14.50 per square foot, will result in significant real estate cost savings, and that there is no additional cost to the company associated with renaming the building.

Willis Tower just sounds odd, for now, at least.

No, it just sounds odd.
