Most buildings date from 1836 to 1874.","why_significant":"The blocks are argued to be an integral part of the community planned by Clement Clarke Moore on his Chelsea estate, with the same historical associations and architectural character as the already listed district. Building covenants produced stylistic variety within uniform dimensions and materials. Greek Revival, Italianate, Anglo-Italianate, neo-Grec and Second Empire styles are all represented, and the district holds the greatest concentration of high-style Italianate and Anglo-Italianate houses in Manhattan.","narrative":"This expansion of the Chelsea Historic District in Manhattan adds about four blocks of mainly residential buildings between Eighth and Tenth Avenues and West 22nd and West 23rd Streets. Most were built between 1836 and 1874 as part of the neighborhood Clement Clarke Moore began developing on his Chelsea estate in 1835. Covenants controlled building dimensions, materials and quality, producing varied detail within a harmonious streetscape. The area includes Greek Revival rowhouses on West 22nd Street, a nearly unbroken row of Anglo-Italianate houses on the north side of that street, and the Italianate mansions of West 23rd Street known as Millionaire's Row, whose stoops were removed in 1929. Neo-Grec and Second Empire buildings, an 1897 neo-Gothic Lutheran church, a 1918 apartment building and the 1930 Art Deco Empire Diner also contribute. A 1963-64 apartment tower is the only intrusion. The addition also matched the larger boundary the city's Landmarks Preservation Commission had already designated.","period_of_significance":"1836-1875","architect_builder":"various","architectural_style":"Greek Revival, Italianate, Anglo-Italianate, neo-Grec, French Second Empire","criteria":[],"status_note":"Condition listed as good and altered; the district is both occupied and unoccupied, with commercial, private residence and religious uses.
