Otto H. Kahn House

The Otto H. Kahn House is a Renaissance Revival mansion built of French limestone across four stories with large arched windows on the first floor level. The structure contains up to 80 rooms distributed across multiple floors, creating an expansive private residence.

The mansion was completed in 1918 and designed by architects J. Armstrong Stenhouse and Charles Pierrepont Henry Gilbert for banker Otto H. Kahn. Its creation reflected early twentieth-century architectural trends when wealthy bankers shaped Manhattan's residential landscape with lavish private estates.

The property now operates as part of a school and retains many of its original architectural features from its period of construction. Walking through the main spaces, you can observe how the design elements reflect the tastes and aspirations of early twentieth-century wealthy New Yorkers.

The property sits on Fifth Avenue in a busy and accessible area of Manhattan. Since it now operates as part of a school, visitors can typically view only the exterior, but you should maintain respectful distance from the building.

The basement contains marble control panels, a rare detail that reveals the meticulous craftsmanship invested in the construction. An oval entrance hall links the different floors in an elegant manner, creating a distinctive flow of movement throughout the building.
