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

Two teams of Rock the Block veterans and two teams of first-time rookies create gorgeous kitchens.

Creativity is king as the teams head downstairs to design their lower levels, complete with kitchens and unfinished spaces; "Battle on the Mountain" star Kim Myles arrives to judge the artistic endeavors.

Ty Pennington challenges the teams with their toughest obstacle yet - transform a bonus loft and staircase in only 48 hours.

It's Week Three and the teams tackle their main suites and make massive moves as some desperately seek their first win.

In Week Two, the teams bring their A-games as they race to finish the rest of their first-floor spaces. HGTV stars Jasmine Roth and Mina Starsiak-Hawk.
