Starting next year, Westfield Siesta Key mall in Sarasota will no longer be a Westfield property. The 435,000-square-foot mall, at U.S. 41 and Siesta Drive in the city of Sarasota, is now owned and operated by O’Connor Capital Partners, a real estate development, investment and management firm with offices in New York, Palm Beach and Mexico City. Unibail Rodamco Westfield and O’Connor previously owned the mall in a joint-venture partnership in which O’Connor owned 49% of the property, but now O’Connor has acquired Westfield’s interest, according to a news release from both companies. Westfield will continue to manage the mall through Thursday, and after that, the property will be rebranded.
