The Hampton Apartments, ca. 1905. While Prospect Park West was developing in the early 20th century, the housing stock was made up of attractive rowhouses and mansions. In 1902 real estate developer Carl J. Zimmerman changed all of that with his plans for an upscale apartment house. The Hampton was six-story brick and limestone structure with an elevator. It was designed by Schwartz & Gross, who would go on to become one of the city's most prolific apartment house designers (particularly on the Upper West Side). The Hampton remained one of the few large apartment houses on PPW for the next 20 years. The late 1920s saw an brief influx in the construction of these types of buildings and the Hampton was victim to that development. It was purchased by developer Samuel Wander, demolished in 1928, and replaced with a 15-story (plus penthouse) building the next year.
