Calling the project a "lifelong dream," Mila Kunis' fiance used the house to express his gratitude for his mother's endless love, reported Ace Showbiz.
Kutcher, 37, remodelled the house with the help of the online home-remodelling site Houzz.
He documented the remodelling process in a series of videos called "My Houzz" for the site. The "Jobs" star also revealed that he and his stepfather Mark worked together to build the house when he was 13-year-old.
"I think everybody has a place in their life that they call home. The renovation that we're going to be doing is on a place that I call home, and I'll always call home. It's a house that I helped build with my stepfather. It's on a gravel road in a little town called Homestead, Iowa," he said.
"It's my way of saying thank you to my mom. My mom has been the greatest influence in my life. My parents gave me everything. They went to great sacrifices to give me the life that I have and anything I can do to say thank you is the right thing.
