The 40-story, 850,000 square-foot office building at 437 Madison Avenue, located between East 49th and 50th streets in Midtown, is currently receiving $60 million in upgrades and renovations, according to Real Estate Weekly. The outdoor plaza and the building’s lobby are being redesigned, building infrastructure is being upgraded, and new amenities are being constructed, including a 15th-floor sky lounge, garden terrace conference rooms, an arcade, and a yoga room. Construction began two years ago and completion is expected early this year. The Emery Roth & Sons-designed building was completed in 1967 and the William Kaufman Organization has owned it ever since. Fogarty Finger is designing the renovation. Medallion Financial Corp. recently extended their 18,650 square-foot lease in the building.

A year ago, YIMBY brought you new renderings of redevelopment plans for the 24-story office building at 380 Madison Avenue, between East 46th and 47th streets in Midtown. By removing certain floors within the building, the structure will grow to 32 stories but will retain the same square-footage. According to the Wall Street Journal, the process is well underway, with 18 percent of the original building in total expected to be removed and used for a vertical expansion. The completed building, called 390 Madison Avenue, will have 663,419 square feet of commercial space, most of which will be office space, although the first two floors will contain double-height retail space. L&L Holding Company is developing the project and Kohn Pedersen Fox is designing it. Completion is expected in early 2017.
