Construction begins on 1.4 million-square-foot office complex in New York city
Construction has commenced the 1.4 million-square-foot development, One Madison Avenue, that will transform the existing full-block structure into a 27-floor, state-of-the-art office complex. The design and development team includes Kohn Pedersen Fox Associates (KPF), developer SL Green, and other partners. KPF's design for One Madison Avenue updates an existing, mid-century podium and adds an elegant new tower along with over an acre of outdoor space and multiple terraces. The glass-enclosed tower will create a dynamic office space across floor plates upwards of 35,000 square feet. © MotivThe 10th and 11th will feature 22' slab heights with expansive outdoor roof decks. By retaining 67 percent of the building's original structure, a notable amount of embodied energy will be reused. The redesign is projected to result in an energy reduction of over 60 percent against the AIA 2030 Commitment baseline, KPF reports. © MotivExisting building. Photo © Kevin Chu and Jessica Paul...
