Harris is part of a group looking to spend more than $300 million to redevelop the massive Railway Exchange Building at 615 Olive, immediately east of Restoration St. Louis’ Hotel Saint Louis project.

Harris’ team envision the 21-story Railway Exchange Building — the former headquarters of May Department Stores and a shuttered Macy’s store — to include a variety of uses, from retail on the street level to apartments and condos to office space.

Tenant agreements have yet to materialize, though Harris said he’s hopeful work on the building will begin in earnest sometime next year.

On the other side of Hotel Saint Louis is the Chemical Building, which has seen a number of development plans come and go over the last decade.

Morgan Communities, a firm based in the Rochester, N.Y., area, bought the building at 721 Olive for $4 million in August 2017 with plans of converting the historic 17-story red brick and terra cotta structure into micro-apartments.

Truman Tolefree, a principal with Morgan, said construction crews are expected to begin work on the project before the end of the year.
