Overview of 50 Madison Avenue

50 Madison Avenue, originally built in 1896 as the headquarters for the American Society for the Prevention of Cruelty to Animals, has undergone a significant transformation into a luxury condominium. Designed by the architectural firm of Renwick, Aspinwall & Owen, the building features a blend of historic charm and modern amenities. The original three floors have been preserved, while eight new limestone-colored floors were added during its conversion in 2005 by Samson Management. This boutique building now houses only nine residences, offering a sense of exclusivity in the heart of the city.

Notable features include floor-to-ceiling windows that offer stunning views of Madison Square Park, the MetLife Clocktower, and the Flatiron Building. Each residence typically includes three bedrooms, each with an en-suite bathroom, and high-end finishes such as herringbone wood floors and modern chef's kitchens equipped with Sub-Zero and other premium appliances. The penthouse units boast additional luxury features, including private outdoor spaces and enhanced interior designs by renowned decorators.

Residents enjoy a range of amenities, including a full-time doorman, individual storage units, and a pet-friendly policy. The building's location provides easy access to some of New York City's finest dining options, such as Eleven Madison Park and Scarpetta, as well as shopping and transportation.
