L&L Holding Company has officially topped off their 32-Story redevelopment Of 390 Madison Avenue in Midtown East. The building has been expanded from 24 floors and 291' to now rise 32 floors and 373'. The office building still features 850,000 SF of leasable office space and the redesign was headed up by Kohn Pedersen Fox. Updates include the removal of concrete and addition of glass on the facade, taller ceiling heights and the addition of outdoor terraces. The redevelopment was permitted under a zoning loophole under the 1961 Zoning Code that allows redevelopment as long at at least 25% of the original structure is maintained. Completion is expected for 2018.
