Oak Park, Ill., the Chicago suburb where Frank Lloyd Wright spent the early years of his career, may be welcoming a new building into the architect’s fold.

The Frank Lloyd Wright Trust this week announced plans for a visitor and education center to be built at the architect’s former home and studio, which has been open to the public as a museum since 1974.

The site is one of dozens the architect designed in the Chicago area, and one of five at which the trust operates public programs and tours. When a property adjacent to Mr. Wright’s former residence went up for sale two years ago, the trust bought it and went to work planning how to better serve the estimated 90,000 people who visit his home each year.

“It has for a long time been apparent that having a visitor’s center would be an important next step,” said Celeste Adams, the trust’s president and chief executive. “But of equal importance is a need to expand programming and provide a deeper educational impact on visitors and on the community in which we exist.”
