One Madison Residential Condominium Tower, 23rd Street, Manhattan, Flatiron District, New York City, New York, United States

At one point, a 22-story building designed by noted architect Rem Koolhaas was to be the building's "companion" on 22nd Street, but later plans called for an 11-story building designed by Cetra/Ruddy, the firm that designed One Madison; although at the time construction began in January 2013, permits had reportedly been issued for a 6-story building, which will include the entrance lobby and two duplex apartments. The companion building, designed by BKSK Architects to feature a terra-cotta and glass façade, will be the primary entrance to the building.
The building is currently owned by a consortium of creditors, including Related Companies, the CIM Group and HFZ Capital Group, who are completing construction and resumed sales in 2013.
As of February 21, 2014, seventy-five percent of the building's units had been sold. NFL quarterback Tom Brady and his supermodel wife Gisele Bündchen purchased a $14 million, three-bedroom condominium at One Madison in October 2013, while News Corp chairman Rupert Murdoch bought the building's triplex penthouse and another full-floor apartment below it for a total of $57.3 million in February 2014.
