Andrew Carnegie Mansion

The Andrew Carnegie Mansion is a four-story residence of red brick and limestone located on Fifth Avenue between 90th and 92nd Streets. The building contains 64 rooms arranged across its levels, now organized as museum galleries and exhibition spaces.

The mansion was completed in 1902 for industrialist Andrew Carnegie, designed by the architectural firm Babb, Cook & Willard. It represented the wealth and influence of America's industrial leaders during the early 1900s.

The house now serves as the Cooper Hewitt Design Museum, where exhibitions show how design shapes everyday objects and spaces. Visitors can explore how design thinking has changed over time and influences what surrounds us.

The building is accessible through entrances on multiple streets, with elevators connecting the floors throughout. Plan time to explore the different gallery levels, as each area displays different collections and themes.

This building was among the first homes in America to use a steel frame structure, allowing for flexible interior designs without heavy supporting walls. The mansion also included early climate control systems that could heat or cool individual rooms separately.
