Graves's prominence as a postmodernist architect may have reached its peak during the 1980s and in the early 1990s, but he continued to practice as an architect until his death in 2015. Later works include the O'Reilly Theater (1996) in Pittsburgh, Pennsylvania; the NCAA Hall of Champions in Indianapolis, Indiana; and 425 Fifth Avenue (2000) in New York City, among others. Graves also received recognition for his multi-year renovation of his personal residence in Princeton. International projects included the Sheraton Miramar Hotel (1997) in El Gouna, Egypt, and the Hard Rock Hotel in Singapore. One of the last projects that Michael Graves and Associates was involved in before Graves's death was the Louwman Museum (2010) in The Hague, Netherlands. Gary Lapera, a principal and studio head of Michael Graves and Associates, designed the museum, also known as the Lowman Collection and the National Automobile Museum of the Netherlands, which houses more than 230 cars.
The kettle featured a red, bird-shaped whistle at the end of the spout. It remained the company's top-selling product for fifteen years. In honor of its thirtieth anniversary in 2015, Graves designed a special edition version with a dragon replacing the kettle's bird-shaped whistle. In Italy in 1987, clock on display Apollodoro Gallery, seventh event The Hour of Architects, with Hans Hollei, Arata Isozaki, Ettore Sottsass, Paolo Portoghesi, paintings by Paolo Salvati, Rome. In 1997–98, when Graves designed the scaffolding used in the restoration of the Washington Monument in Washington D.C., he met Ron Johnson, a Target executive who appreciated his product designs. (The Target Corporation contributed $6 million toward restoration of the monument.) The result of their acquaintance was the formation of a business relationship between Graves and the U.S. retailer that lasted until 2012. Graves began the collaboration with Target by designing a half-dozen products for the mass-consumer market. His collection of housewares began selling in Target stores in January 1999.
Graves died at his home in Princeton, New Jersey, on March 12, 2015 at the age of 80, and is buried at Princeton Cemetery.
