Four teams of HGTV all-stars return, designing gorgeous kitchens in a quest for redemption as the ultimate renovation competition begins. After battling an open floor plan, the teams are judged by Married to Real Estate's Egypt Sherrod and Mike Jackson.

The competition heats up as the teams head outside to tackle their backyards and pools in a Rock the Block first. Teams have a front row seat to each other's designs before Rock the Block Season 2 Winners Brian and Mika Kleinschmidt return to judge.

It's week two and the teams create their living room and first floor spaces. It's a game of beds, baths and views plus a twist on judging as 100 Day Dream Home's Brian and Mika Kleinschmidt assess the jaw-dropping spaces and declare the winning team.

Week three, the competition heads upstairs to the Main Suite where teams attempt to redeem themselves with their spectacular designs. Farmhouse Fixer's Kristina Crestin comes to judge and determine who's got first-rate taste.

Teams stay outside in week five as they design their docks, balconies and front exteriors. Ty asks everyone to get artsy in his latest Design Surprise before Rock the Block winner Michel Smith Boyd and HGTV star Veronica Valencia judge the luxe spaces.

The teams sprint to add the most value in their final spaces before a winner is named and redemption earned. Teams also tour each other's houses for the first time while Property Brother, Jonathan Scott judges their work.

The road to redemption isn't easy as Ty surprises the teams with their toughest challenge: completing a bedroom flex space in 48 hours. MLB great Jimmy Rollins teaches the teams to get an advantage, and in a Rock the Block first, teams judge THEMSELVES.
