Duplex Residence 9, 27 East 79th Street, New York City

Location aside, the fact that this development has Parisian firm Cabinet Alberto Pinto—an agency known for designing the interiors of yachts, private jets and lavish estates including the Élysée Palace—behind its design is enough to place this property in the spotlight. The building is home to just eight residences, including this five-bedroom, five-and-a-half-bathroom duplex. Behind its Beaux Arts and Art Nouveau facade, opulent details flow throughout, from the lobby’s French limestone tiles and Noir Saint Laurent marble to the residences’ white oak parquet flooring and Estremoz, Calacatta Vagli and Emperador Foncé marble slabs and tiling. Finishing touches include polished nickel Kallista Vir Stil fixtures, custom cabinetry and European-style kitchens with French ranges by La Cornue, Cremo Delicato marble and appliances by Miele and Sub-Zero. Residences come with a 24-hour concierge, and the building’s position on the Upper East Side means you’re just a short stroll from Central Park, as well as cultural institutions like the Guggenheim Museum.
