A 95 percent interest in 80 Broad St. is being sold to Atlanta-based Invesco.
Set to close by year-end, the recapitalization by the global investor will revalue the 425,000-square-foot building at $235 million, or $550 per square foot, one of the highest prices achieved for Downtown B-class offices.
The seller, Broad Street Development, led by Raymond Chalmé and Daniel Blanco, will retain a 5 percent stake and continue to manage and lease the 36-story Art Deco tower.
The deal was marketed by Douglas Harmon, Adam Spies and Joshua King of Cushman & Wakefield.
Built in the 1930s as the Maritime Exchange, 80 Broad has a seafaring history reflected in such architectural details as sea horses on elevator doors.
Spokesmen for both C&W and BSD declined to comment, and Invesco did not return a request for comment.
