Cobble Hill housing is dominated by 19th-century brick rowhouses with picturesque stoops, three-to-four-story Italianate and Romanesque homes, and classic Brooklyn brownstones. Like neighboring Carroll Gardens and Brooklyn Heights, the architecture is the neighborhood's signature. Single-family townhouses, two-to-four-family brownstones, and pre-war co-ops dominate. New construction is rare given the historic character. To browse Cobble Hill listings, call (718) 666-2696.
