Miami Beach, Fla. — Whitman Family Development is planning a 300,000-square-foot expansion of Bal Harbour Shops, including a new Barneys New York location and three-story promenade. The company has received $550 million in financing to expand the iconic center in Miami Beach. The 463,114-square-foot mall is home to anchors Saks Fifth Avenue and Neiman Marcus. Miami-based Whitman Family Development will use $150 million of the loan to pay off an existing loan and $400 million to expand the center by 300,000 square feet, bringing the total to 763,114 square feet. The expansion will include a 57,414-square-foot space to be occupied by Barneys New York, a three-story promenade that will be added to connect Barneys to the existing palm tree-lined promenade, a new grand entrance at the northeast quadrant of the property and the expansion of the Neiman Marcus space by 20,000 square feet. MetLife Investment Management provided the loan. The $150 million portion features a fixed interest rate for eight years while the $400 million portion is underwritten with a floating interest rate. Other tenants at Bal Harbour Shops include Chanel, Gucci, Van Cleef & Arpels, Tiffany & Co., Salvatore Ferragamo and Valentino.
