This week, the teams tackle two Tudor-style homes across the street from one other. Team Red (headed by Tennessee-based builder Tarrick Love) attempts to build a bathroom vanity from a repurposed work bench and create a new dining room table out of the original kitchen's beloved hardwood floors. Team Blue (headed by Chicago builder Jay Riordan) must decide what they should do with the master bedroom. In a surprise twist for the contestants, Berkus invites a "neighborhood council" to vote on which house they feel is the best makeover. In the end, one designer from the losing team will be sent home.

This week the focus is on bringing a "dream home" to reality. The contestants are challenged to create a stunning "outdoor oasis" and, in the midst of things, must deal with a massive rainstorm that causes delays and frustrations. Team Red (headed by Chicago-based designer Lukas Machnik) focuses on creating a tranquil master bedroom, an inviting indoor/outdoor space and they also take on several creative special projects, including a chicken-wire light fixture and a metal sculpture. The team struggles with time management and spends too much time on the sculptures. Team Blue (headed by New York-based designer Andrew Flesher) focuses on the front exterior and the overall interior color scheme. Sparks fly when Team Blue designer Elaine Griffin chooses a color for her living room that everyone else dislikes for the rest of the home's color scheme. After the judges review the homes, Berkus invites a local "neighborhood council" to vote on which house they feel is the best makeover. In the end, one designer from the losing team will be sent home.

On Team Red, Lukas Machnik and Elaine Griffin find difficulty in site manager Darren Moore's casual work style. Ultimately, one designer is sent home.
