Its architect and builder are unknown.","why_significant":"The house is a rare, intact survivor of the late Federal style mansions that once lined St. Mark's Place, with limestone detail, a James Gibbs inspired door surround and ironwork. It was part of what is believed to be one of New York City's first large development schemes, by Thomas E. Davis. It also reflects the prosperity and social standing of the old New York families who lived in this fashionable 1830s and '40s neighborhood.","narrative":"Built in 1832 on the south side of St. Mark's Place between Second and Third Avenues, this three-and-one-half story rowhouse is a surviving example of late Federal style housing in Manhattan. It is twenty-six feet wide, with a limestone basement and stoop, red brick upper floors laid in Flemish bond, and a large arched doorway with a vermiculated triple keystone inspired by James Gibbs. Original iron stoop railings remain. The house was one of a group erected by developer Thomas E. Davis for speculative sale, in what is believed to be one of the city's earliest large development schemes. Davis later founded New Brighton on Staten Island. The area was then a fashionable address for well-to-do branches of old New York families. Daniel LeRoy, who bought the house, married Susan Fish, sister of Hamilton Fish. After the Civil War the neighborhood turned commercial, and the basement is now a bar and grill, with a shop above it and apartments on the upper floors.","period_of_significance":"1800-1899","architect_builder":null,"architectural_style":"Late Federal","criteria":[],"status_note":"Occupied: the basement has been converted to a bar and grill, the first floor is an electronics shop, and the upper floors are residential.
