An architectural marvel built for the union of two of Fort Worth’s most influential families just hit the market for a cool $22 million.

The 19,000 square foot house in Westover Hills is one of three private homes designed by world-famous architect I.M. Pei.

Some of Pei’s other works include the Louvre Museum Pyramid in Paris, the John F. Kennedy Library in Boston, and Dallas City Hall.

Pei designed the Westover Hills home in 1969 for former Tandy Corp. CEO Charles Tandy and wife Anne Burnett, the oil and ranching heiress.

Burnett loved throwing parties, so she wanted the house to have a lot of space, Pei said in a 1970 Home and Garden Magazine interview discussing the design.

“She needed a house that would be comfortable for two people — or two or three hundred,” he said.

Pei told the magazine he took inspiration from the Isabella Stewart Gardner Museum in Boston, built in the style of an Italian Palazzo with a central courtyard surrounded by gallery rooms.

The house’s garden room plays a similar role with a slanted ceiling of glass panels that let natural light filter into the home.

In its 57-year existence, the home has hosted weddings, debutant balls, and fundraising dinners for presidential campaigns.

During Tandy’s 60th birthday party, he and Burnett rode an elephant around the driveway courtyard.

It also hosted the art collection of Burnett’s daughter and namesake of TCU’s medical school, Anne Burnett Marion. The collection was actioned for $157 million after Marion’s death in 2020, according to Paper City Magazine.

In addition to contributing $50 million to support the medical school, Marion used her family’s resources to support Fort Worth’s artistic institutions.

She was central to the development of the Modern Art Museum of Fort Worth both financially and stylistically.

After finding one of the then-new museum’s walls distracting, Marion had it torn down and rebuilt to ensure patrons would focus on the art.

The concrete home, tucked behind trees, sits on about 3.86 acres, and was appraised at $7.9 million in 2025, according to the Tarrant Appraisal District.

In addition to the garden room, the house includes seven bedrooms, seven bathrooms, two formal dining rooms, two formal living rooms, an art gallery, three kitchens, and a pool.

The property is being listed by Ashley Mooring of Briggs Freeman Sotheby’s International Realty. She is sharing the listing with Ralph Randall and Madeline Jobst.
