Almost three years ago, Cindy Landon decided she was ready to move out of the house she built with her late husband, TV star Michael Landon, on an 11-acre land in Malibu, California.

Her plan was to stay in town. She looked around and came across a beautiful double-parcel beachfront property on Seafield Drive with an older house that needed some work.

“The minute I saw it, it reminded me the house we lived in the south of France many years ago,” Ms. Landon said. “The ocean view is spectacular. It’s also lushly green on the property with a gazebo and koi pond. The vibe is just right.”

She purchased the property for $7.5 million in late 2015 and took on a major renovation with the help of Malibu architect Doug Burdge.

“I redid everything inside. The house is now upgraded with smart home technology, state-of-the-art appliances and all the high-quality finishes and amenities,” said Ms. Landon, 61, a film producer known for “The Game Changers (2018)” and “Sanctuary (2016).”

The 6,904-square-foot residence has five bedrooms, six bathrooms, a chef’s kitchen, a media room with a wet bar, a wine cellar and a humidor.

The best part of the house is that “every room has amazing views. And the sliding glass walls blend the indoor and outdoor living seamlessly,” Ms. Landon said.  

She spent over $4 million for the renovation, which was completed two months ago. However, when it was time to move, she had a change of heart.

“I had intended to make it my new home, but I felt emotional to move out of my old house,” she said. “It was a tough call.”

After much thought, she asked her son, Sean Landon, a real estate agent with Coldwell Banker Residential Brokerage, to put the newly renovated beachfront house on the market.

The property hit the Multiple Listing Service on July 10. The asking price, $18 million, took into consideration the renovation cost, the permitting process and the unique features of this house, said Mr. Landon, who grew up in Malibu.

“We renovated the house down to the studs. Everything modern in Malibu is very rare,” he said, adding that the extra parcel has the potential for a new structure.

His parents met on the set of “Little House on the Prairie,” where his mother, Cindy, was a makeup artist and his late father, Michael, starred as Charles Ingalls during the show’s nine-year run.

Michael Landon was also a star and producer of hit TV series “Bonanza” for 14 years. The couple was married from 1983 till 1991, when he died at age 54.
