Home Depot co-founder Bernie Marcus and his wife, Billi, have put their north Sandy Springs mansion on the market for just over $3 million.

The five-bedroom, eight-bathroom stucco home sits on 3 acres near the Chattahoochee River on Wildercliff Drive. Real estate agent Betsy Akers of Atlanta Fine Homes said Monday she was in the process of showing the home to an entertainer, whom she declined to identify.

According to data provided by atlantafinehomes.com the 10,314-square-foot home comes with a guest house, staff quarters and caretaker house. The two-story home also has an indoor pool, fitness center, wine cellar, workshop and two offices. The listing price is $3.2 million.

According to Fulton County tax assessors records, the structure, built in 1987, is valued at $2.4 million and the land at $784,400.

Akers said the Marcuses have been the only occupants since the custom home was built on property they purchased in 1985 for $260,000. “Everything in the home is state of the art,” Akers said.

She said the market for high-end homes in metro Atlanta continues to improve and that she has sold several million-dollar homes without listing them. “There are all kinds of sales taking place, which indicates confidence in the Atlanta market,” Akers said.

Forbes magazine puts Marcus’ net worth at around $3 billion. He co-founded Atlanta-based Home Depot in 1978 with Arthur Blank, now owner of the Atlanta Falcons, and the company is now the world’s largest home-improvement retailer.

Marcus, who now lives in Boca Raton, Fla., retired as chairman in 2001 and has donated millions of dollars since then through his Marcus Foundation, including $250 million to open the Georgia Aquarium.

He has also funded medical research and opened the Marcus Autism Center in Atlanta in 2008. Earlier this year, the Marcus Foundation donated $25 million to Boca Raton Regional Hospital to create the Marcus Neuroscience Institute at the hospital to treat patients with epilepsy, multiple sclerosis, Alzheimer’s disease and other brain disorders.

When the gift was announced in January, Marcus said during a news conference that he and his wife decided they no longer wanted to travel to Atlanta for medical care.

“We have friends with Alzheimer’s disease, dear friends,” the Sun Sentinel quoted Marcus as saying at the time. “You see it all around you. The time was right for this 10 years ago.”

The institute is expected to open in 2014.
