Just in time for Mother’s Day, Ashton Kutcher teamed up with the home site Houzz.com to surprise his mom, Diane, with a basement remodel in his family’s Iowa house. The process — from planning to the reveal — is part of a four-part video series, and it’s wonderful.

“At the end of the day, it’s my way of saying thank you to my mom,” Kutcher says in the video. “Anything that I can do to say thank you is the right thing to do.”

While Diane was helping Kutcher’s fiancé, Mila Kunis, with their baby daughter in California, Kutcher and his step-dad, Mark, transformed the basement from a man cave — complete with John Wayne memorabilia, recliners and loads of Chicago Bears gear — to a rustic retreat with an open-style kitchen, a sitting area, a guest room for grandchildren and even an upscale pantry for Diane’s famous salsa.

Diane’s reaction did not disappoint. She tearfully walked through the space, although her son assured her, “You don’t have to cry in every room.”

“Being able to do this for my mom is like a life-long dream,” Kutcher said. “I don’t know that there’s anything I can ever do that really says thank you, but trying sure feels good.”
