There are many blocks in New York that leave us drooling, but the original “block beautiful” is 19th Street between Irving Place and Third Avenue, one block away from Gramercy Park. Most of the brick and brownstone rowhouses on the block were built in the 1850s but were considered dour by the turn of the century. After moving to New York in 1906, British architect Frederick Sterner bought the home at 139 East 19th Street and renovated it with what would become his playful signature touch: a coat of tinted stucco, shutters, decorative ironwork, and a projecting tile roof. Many—if not most—of the other homes on the block received Sterner makeovers, giving the street a distinctive charm. Now you can own the house right across the street from Sterner’s own, at 140 East 19th Street, for $15,250,000.
