The Property Brothers are almost ready to share their biggest project ever.

The Canadian home reno superstars Jonathan and Drew Scott have been hard at work restoring the original “Brady Bunch” house, used for exterior shots in the classic sitcom, and they spoke to Us Weekly about the whole process.

“The house was just an exterior — nothing was shot inside. Now, we’re putting the interiors you saw on TV in the home, which was one of the most massive projects we’ve ever done,” Jonathan said. “We brought back the ‘Brady’ cast, who are all in there swinging sledgehammers.”

Maureen McCormick and Christopher Knight, who played Marsha and Peter Brady on “The Brady Bunch”, joined the Scotts to help with the restoration.

Drew also revealed that they got help from “Brady” fans around the world who gave up their precious memorabilia to be included in the house’s renovated interior.

“Trying to find all these authentic [decor] items and one-of-a-kind elements was really fun too,” he said. “Fans have all this memorabilia from the original show and offered it up to us for free.”

Another partner in the project is Lance Bass, the former N’Sync member who had tried to bid on the house in 2018, losing out to HGTV. Bass was later brought on as a producer on the series and actually got to work on the house.

“A Very Brady Renovation” is set to air this year on HGTV.
