Sergio Rossi has signed a long-term lease for an 800-square-foot store at 680 Madison Avenue, according to Thor Equities, which owns the property. The Italian footwear company will have plenty of high-fashion neighbors at 680 Madison, or the Carlton House, as the building is known. Missoni recently said it will move from 1009 Madison Avenue and 78th Street to a 3,500-square-foot unit at 680 Madison.

Sergio Rossi doesn’t operate a freestanding store in Manhattan; the brand is sold at Bloomingdale’s, Saks Fifth Avenue and Barneys New York.

Tom Ford occupies a two-level, 12,300-square-foot flagship along the southwest corner of the same building, but the store has the address 672 Madison Avenue. The designer in 2017 relocated to the new space from 845 Madison Avenue at 70th Street. Other tenants include British fashion house Ralph & Russo, luxury men’s wear brand Brioni and Morgenthal Frederics eyewear.

Built in 1951 by the Astor estate as a hotel, the property, which runs the entire length of Madison Avenue between 61st and 62nd Streets, was later converted to the Helmsley Carlton House before becoming a luxury residential property with 34,000 square feet of retail space.

Madison Avenue has struggled with declining rents and high vacancies since the 2008 recession, however, leasing activity picked up in the fall. Balenciaga will open a store at 610-620 Madison Avenue in the spring and Celine will unveil a store at 650 Madison Avenue. Balenciaga and Celine will relocate existing stores at 840 Madison Avenue and 870 Madison Avenue, respectively.
