Cooper-Hewitt National Design Museum is unique not 
The mansion, located on Fifth Avenue at 91st Street, is majestic with its Georgian-style architecture, grand wood-paneled foyer, sweeping staircase, and large private garden, setting the perfect backdrop for an institution dedicated to architecture and design. With more than 250,000 design pieces in Cooper-Hewitt’s collection, the museum’s permanent holdings are housed in various wings of the mansion, all of which are open to visitors by advance appointment only. Meanwhile, the main portion of the mansion is open to the public and devoted exclusively to a series of rotating exhibits that provide casual visitors a glimpse into the world of design.
