Julie and Billy Macklowe upsize at 1001 Fifth Ave

Developer Billy Macklowe and his wife, Julie, are expanding their digs at 1001 Fifth Avenue.

The Macklowes just dropped $4.5 million for a 19th floor unit at the tony co-op building where they’ve lived since 2004, according to documents filed with the city. Records show the seller was Brazilian banker Aloysio de Andrade Faria. The three-bedroom was listed for $4.75 million with listing agents Harry Nasser and Olivia Hoge of Sotheby’s International Realty.

The Macklowes owned several units on the 20th and 21st floors at 1001 Fifth, located at East 82nd Street across from the Metropolitan Museum of Art. They purchased their original apartment (a combo unit on the 20th floor) for $6.8 million, records show. In 2014, they spent $5.3 million for a unit one floor down. The couple, who declined to comment, also owns a home in Sagaponack.

Billy Macklowe is the founder and CEO of William Macklowe Company, which he started in June 2010 after splitting from his father Harry’s firm, Macklowe Properties.

The younger Macklowe’s portfolio now includes 156 William Street and 21 East 12th Street, the former Bowlmor Lanes site he converted to condos.

Earlier this month, Macklowe and Principal Real Estate Investors inked a contract to sell 311 West 43rd Street to a California real estate investment firm for $130 million. They purchased the 186,000-square-foot Midtown tower for $107 million in 2015.
