Rock the Block: Season 4

Four teams of HGTV all-stars design breathtaking kitchens as the ultimate renovation competition begins. After a hot-air balloon ride over the mountains offers inspiration, Fixer to Fabulous' Dave and Jenny Marrs judge the jaw-dropping finished spaces.

In week two, the teams create stunning Living Rooms and Entryways for their homes. Fireplaces and Rocky Mountain views seem like a sure thing until Rock the Block alum Mina Starsiak-Hawk and HGTV's Jenn Todryk tour everyone's work and pick a winner.

It's week three and the competition turns up as the teams renovate their main suite. Elevated designs rule the day as Unsellable Houses stars Lyndsay Lamb and Leslie Davis come to blind judge and determine if any team left things too basic.

With the first floor complete, the teams head downstairs to tackle the biggest space ever seen on Rock the Block: the Lower Level, 1500 square feet of blank canvas to create some of the most outrageous spaces ever seen. HGTV's Alison Victoria and Veronica Valencia wade through the luxurious fun to choose a winner.

Time to head outside as teams design their exterior spaces during a snowy week on the block. Ty encourages everyone to get sporty thanks to his last Design Surprise and Rock the Block Season 2 winners Brian and Mika Kleinschmidt arrive to judge.

With budgets dwindling and pressure mounting, everyone races to the finish line. Teams finally get to see each other's homes as previous Rock the Block champions Jasmine Roth, Egypt Sherrod, and Mike Jackson judge their work and announce the winning team.
