Gallery owner Stefania Bortolami packing up her self-titled shop at 510 West 25th Street and moving five blocks south to 522 West 20th Street, both between 10th and 11th avenues. The move marks an upgrade for the dealer — at 6,000 square feet, her new digs are 2,000 square feet larger than the last. Bortolami, who had been at the 25th Street location for five years, said that she selected her new locale based on its anti-cutesy air. “Twentieth Street isn’t charming. It isn’t lined with trees,” Bortolami said. “It feels a bit rough, and that’s nice.” Her transition to a new space comes on the heels of a massive gallery migration around the West 20s, which industry experts pin to recent “shifts in the New York real estate market,” ArtInfo said.
