Ashton Kutcher showed his appreciation for his mother in a big way ahead of this year’s Mother’s Day, by remodeling part of the Iowa home he grew up in.

The former Two and a Half Men star, who recently became a first-time father, built the home with his stepfather when he was 13 years old.

He used Houzz to make this happen, a website that allows home design from anywhere in the world. Kutcher is an investor in the site.

“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,” he explained, TIME reports.

“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.”

When it came time for the big reveal, after 27 days of renovations and help from his stepfather Mark, his mom was stunned.

“It does mean a lot to me, it’s beautiful,” she said.
