PRINCETON, N.J. (AP) _ An Indianapolis-born architect who designed modern and whimsical postmodern structures and later household goods sold at Target stores has died in New Jersey. Michael Graves was 80 years old.

Spokeswoman Michelle DiLello says Graves died of natural causes Thursday in his longtime hometown of Princeton.

Graves designed buildings including the Portland Building in Oregon, and the Humana Building in Louisville, Kentucky. He also did a campus master plan for Rice University in Houston and designed the scaffolding that surrounded the Washington Monument during a restoration project.

His buildings often had a sense of whimsy. At 1 Port Center in Camden, New Jersey, he used yellow and blue to liven up an office building. <br />
Graves has had branded lines of housewares including teapots and colanders for sale at Target and JCPenney stores since 1999.
