See an Exclusive Sneak Peek of the "Fixer Upper: The Castle" Finale

Chip and Joanna Gaines gave a Waco castle a makeover that you must see to believe.

Chip and Joanna Gaines' biggest fixer upper yet is ready to be revealed!

After renovating a castle home in Waco, Texas, the Magnolia founders are showing off the fruits of their labor in the sixth and final episode of Fixer Upper: The Castle.

"This project was the fixer upper of all fixer uppers. I mean, these historic restorations are a totally different ballgame," Chip says in an exclusive clip shared with Parade.com. "When you think about the exterior, we redid the stone and I would say it was like a brand new, fresh version of the castle, but it was quite the debate."

Joanna adds, "Any other house, I just feel like I know what I want and I'm really direct. I'm quick. Something about every time I came to the castle, I just felt kind of paralyzed like I would just freeze and I wouldn't know what decision to make."

The Stories We Tell author admitted in the exclusive clip that the castle's stone had her "kind of stumped." "Chip would have to step in and just make the decision for me because I didn't want to mess up and now every time I pull up I'm like it was a good decision," Joanna says.

The Fixer Upper stars purchased the over 100-year-old castle, known as "Cottonland Castle," in 2019. "Chip never ceased dreaming aloud about how fun it would be to restore the house to its former glory," Joanna wrote in the winter 2019 issue of Magnolia Journal.

The Magnolia Table star revealed in her note that Chip saw the "beauty and potential" in the property years before she did. "No doubt about it, this is a fixer-upper unlike any other we’ve ever tackled," Joanna penned. "Even though we haven’t the slightest idea of what it will become, what Chip did know all along, deep in his bones, and what I have learned to see too, is this: If you look past the cracks in the masonry, past the rotted floorboards, past the wilderness taking over the backyard, there is a lot of beauty to be found in this old castle."

While at the time there was "no knowing exactly how" their adventure would turn out, Joanna wrote that "the dream—Chip’s dream from so many years ago, the dream of what this wonderful old home could become—that dream is still very much alive. Mostly because Chip and I have learned to be faithful to the process. We’ve known intimately the reward that’s waiting for us on the other side, the payoff that comes with a willingness to dig in, to fight for something within a project or within ourselves that we may not even be able to identify. And to trust with abandon that there’s beauty to be found in everything."
