Biography
Henry Janeway Hardenbergh (1847–1918) designed two of the most architecturally significant residential trophies in Manhattan: the Dakota (1884) at 1 West 72nd, the earliest luxury apartment building on the Upper West Side and arguably the most culturally iconic apartment building in the city; and the Plaza Hotel (1907) at Fifth Avenue and Central Park South, whose residential conversion in 2007–2008 created the Plaza Condominium. Hardenbergh's interiors set the standard for 13-foot ceilings, formal entry galleries, and multiple wood-burning fireplaces that defined the Gilded Age apartment program — features that, where preserved, continue to drive a measurable premium in the resale market 140+ years after the Dakota's completion.
