115–119 Eighth Avenue, also known as the Adams House, is a historic house at Eighth Avenue and Carroll Street in Park Slope, Brooklyn, New York City. It was built in 1888 as a double house, and was commissioned by Thomas Adams Jr., who invented the Adams Chiclets automatic vending machine. It was designed by noted architect C. P. H. Gilbert in the Richardsonian Romanesque style, and is considered to be one of the best examples of that style extant in New York City, "worthy of H. H. Richardson." The house is built of sandstone, terra cotta and brick on a brownstone base, and was the first house in the neighborhood with an elevator. It has now been converted into apartments.
