This week's episode of Fixer Upper gave the viewers yet another treat as another special guest join Chip and Joanna in the demo zone. The HGTV celebs are jam-packing their star-studded final season with surprises. Just last week we saw former First Lady Laura Bush donate a tree from the Bush family ranch for a new homeowner.

In the latest episode, former football star and current minor league baseball player Tim Tebow came to Waco with a special request for the Fixer Upper duo.

Tim and his foundation, the Tim Tebow Foundation asked Chip and Jo to build a house for the Copp family. Jody and Melissa Copp have two little boys, Calan and Lawson who both need a wheelchair accessible home.

Mom Melissa described her sons as having a "life-threatening condition that affects their ability to stand and walk on their own and they started using wheelchairs at a very young age."

Never ones to shy from a challenge, Chip and Joanna accept and get to work creating the perfect, ADA approved, accessible family home for Mom, Dad, Lawson and Calan. No detail goes left undone. Jo even calls on beloved carpenter Clint Harp to design a table in the kitchen where all members of the family can sit—in chairs or on wheels.

As the build progresses, other organizations step in to help and donate various items and services. When all is said and done, Tebow is on hand for the big reveal!

Not only is it the perfect home inside, but the boys finally have a backyard that is a safe haven for Calan and Lawson to, as dad Jody said, "let my boys just be boys."

Welcome home Copp family! And Kudos Tim Tebow!
