Cadillac Fairview, which operates the mall, will invest $25 million to transform the current space “into a visually appealing, comfortable, efficient and modern workplace,” it said.

The new office will open January 2019 in the mall which has more than 140 retailers and food vendors.

The transformation is also an indication of what’s happening across the country as landlords look at creative and different ways to fill the thousands of square feet of empty space created with the collapse of the former retail giant, Sears.
