"Housed in Andrew Carnegie's former Georgian mansion, the Cooper Hewitt, Smithsonian Design Museum still conserves the original dark wood-lined interiors and imposing staircase, even after closing for a few years for a major upgrade in the hands of Diller Scofidio + Renfro, among others. The shop on the second floor is part of the revamp, too, with the architectural firm's custom modular shelving framing the tailor-made space. The wonderful mix of beautifully designed objects and utilitarian goods remains the same, however, and from designers young and old, from Ben Medansky vases to Tom Dixon spice grinders, and much more. It is by far one of the best museum shops on the planet. "
