It's a tight race on the Gulf Coast between Jonathan's 1980's seaside bungalow and Drew's 1970's two-story classic coastal; the loser rides The Cyclone at the local amusement park multiple times.

The heat is on as Drew and Jonathan renovate their kitchens before Brett Waterman comes to town to deliver his verdict. One brother knows it's time to up his game because the winner gets to try fly boarding in the Gulf.

The competition continues and Drew sets out to win with an over-the-top master suite. The brothers will have to work extra hard on their bathrooms and bedrooms as Desert Flippers' Eric and Lindsey Bennett are on hand to judge their work. The winner gets to play with penguins at the Moody Gardens Aquarium in Galveston, TX, while the loser has to clean up the mess.

The brothers come out swinging to see who can design the best party-ready outdoor decks and patios. Mother and daughter duo Mina and Karen from Good Bones come by the coastal houses to judge the brothers' projects. Whoever impresses the judges the most gets to zip line to the beach while the loser has to navigate an 80-foot rope obstacle course.

Jonathan and Drew Scott re-design their guest bedrooms and bathrooms for Tiffany Brooks and Ben Sargent to judge. The loser has to go out into the Gulf to catch shrimp and then cook a meal for the winner and the judges.
