The teams head outside because it's all about exteriors and landscaping on the block this week. Each designer knows the importance of curb appeal, and this challenge could be the difference between winning and losing the whole competition. Interior designer Carmine Sabatella and landscape designer Mike Pyle, stars of the upcoming HGTV series Inside Out, will evaluate the outdoor spaces.

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.

Two teams of design veterans and two teams of rookies create new kitchens and living rooms as the renovation competition kicks off, but as surprising delivery gets dropped off and Bobby Berk joins as a judge.

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.
