The added area holds 163 contributing and 34 non-contributing buildings. Most are four- and five-story rowhouses built largely in the 1870s as brownstones in Italianate and Neo-Grec styles, many later rebuilt in Neo-Georgian, Neo-Federal or Tudor Revival dress or fitted with shops. Apartment houses of six to 15 stories, mostly from the 1920s, line Park and Lexington Avenues and East 72nd Street. The 25-story Barbizon Hotel, built in 1925 as a women's residence, is also included. The amendment extends the period of significance to 1956 and reclassifies several postwar buildings as contributing. Three Modern landmarks receive separate recognition: Asia House by Philip Johnson, the Whitney Museum building by Marcel Breuer, and a townhouse by Paul Rudolph.","period_of_significance":"1862-1956 (plus 1959, 1966 and 1968 for three individual buildings)","architect_builder":"Many architects named, including John Sexton, Hill & Stout, Murgatroyd & Ogden, Thomas W.
