Inside the Gilded Age Mansion Shaping the Future of Design

Housed in Andrew Carnegie’s former home, the Cooper Hewitt Smithsonian Design Museum looks at how innovation, technology, and design continue to shape the way we live today.

Completed in 1902, the Andrew Carnegie Mansion stands as one of New York City’s great Gilded Age landmarks. Yet the home of the Cooper Hewitt, Smithsonian Design Museum is more than a preserved relic of another era. In many ways, it continues to embody the same ideals that inspired its creation: innovation, experimentation, and a belief in design’s power to shape everyday life.

When Andrew Carnegie built the mansion on what was then the northern edge of Manhattan, it was considered remarkably forward-thinking. One of the first private residences in America to feature a full steel frame, passenger elevator, and advanced heating systems, the house was conceived as a technological marvel as much as a family home. Every detail reflected the optimism of a moment when industry, invention, and progress were transforming not just New York City, but the entire country.

Today, those same ideas guide the museum that occupies the Carnegie’s former home. While the richly paneled dining room, gilded music room, and intimate library preserve the atmosphere of Carnegie’s world, the Cooper Hewitt uses these historic spaces to explore contemporary questions about design, technology, and the future. Exhibitions examine everything from industrial manufacturing and sound design to the systems, objects, and innovations that shape everyday life.

That conversation between past and present is perhaps most striking in Carnegie’s former library. Once the private study where the industrialist met with colleagues, philanthropists, and cultural leaders, the room now hosts artist and audio engineer Devin Turnbull’s immersive listening installation, HiFi Pursuit Listening Room Dream No. 3. Custom-built speakers, handcrafted audio equipment, and carefully calibrated acoustics transform the historic space into a place of contemplation and discovery. The setting could not be more fitting: a room originally dedicated to ideas now invites visitors to experience how design, technology, and sound continue to evolve more than a century later.

As the Cooper Hewitt approaches two major milestones—the nation’s 250th anniversary and the museum’s own 50th anniversary in the Carnegie Mansion—the institution is looking forward as much as back. A new exhibition, Design Across Time: Exploring the Smithsonian’s Design Collection, brings works from the National Design Collection into the historic first-floor rooms of the mansion, creating fresh connections between the building’s past and the innovations shaping its future. It is a fitting next chapter for a home that has always been defined not simply by what is preserved, but by the ideas it inspires.
