Brownstones are an indelible feature of New York City’s distinct architectural landscape. New York City has the largest compilation of brownstones in the United States—by far. They are the primary residential units in Bedford Stuyvesant and the Upper West Side. Harlem, Queens, and the Bronx also host a swath of the iconic homes. Brooklyn, in particular, is defined by its brownstones. They line the streets of Fort Greene, Park Slope, Prospect Heights, and Cobble Hill, and are scattered in bundles from Greenpoint to Red Hook. Many of these brownstones are now the most desirable (and expensive) properties in the borough.
