Rock the Block - Die HGTV Umbau-Challenge

The competition kicks off as four teams of HGTV superstars put their expertise to the test with an amazing kitchen transformation. Farmhouse Fixer's Jonathan Knight and his brother, Jordan, go step-by-step to judge each of their breathtaking designs.

First impressions are everything as each team reimagines their home's living room and entryway to showcase their unique design styles. Rock the Block's season one winner, Jasmine Roth, returns to judge the renovated spaces and choose a winning team.

The teams finish their first floor renovation as they tackle the main bedroom suites. It's the ultimate test of luxury versus functionality as Rock the Block veteran Alison Victoria and HGTV star Page Turner judge these jaw-dropping spaces.

The teams go upstairs to renovate a new Rock the Block space -- the FROG.

With budgets dwindling and pressure rising, the teams head outside to design their outdoor spaces. It's all about curb appeal and backyard amenities until Ty disrupts their plans just before Mina Starsiak-Hawk and Karen E Laine begin their judging.

The teams race to finish their houses before their money runs out and judgement day arrives. Drew Scott and previous Rock the Block winners Brian and Mika Kleinschmidt judge the entire homes while each team finally gets to see their competitions' spaces.

HGTV takes an exclusive, never-before-seen look at all things Rock the Block as the competing teams reveal everything from what they really felt during judging to who led the most pranks in this season's biggest bloopers, outtakes and deleted scenes.
