Banksy Exhibit Takes 25,000 SQFT Former H&M Flagship as Union Square Owners Turn to Pop-Ups to Fill Big Boxes

A ticketed Banksy exhibition will occupy 25,000 square feet of the long-dark former H&M flagship at 150 Powell St. from Dec. 4, while Lincoln Property Co. and Cara Investment have wrapped the shuttered Saks Fifth Avenue building at 384 Post St. in an interactive mural, two stopgap bets on activation as Union Square works through its largest vacancies.
