With another house key up for grabs, the action kicked off with a White Room ‘Car Wars’ Challenge. Teams of three were required to renovate a room based around a car obtained from the wrecker’s yard, incorporating as much of the car into their design as possible. The ideas all showed immense creativity, but it was the Formula One-inspired executive suite produced by Peter, Chris, Lisa, Laura, Tina, Christie and Samantha that won the judges' vote, sending them through to the Basic Skills Challenge. The first round was wallpapering, with Peter, Chris and Lisa the standout performers. The final round saw the trio painting walls, which had to be completed to the judges’ satisfaction. It was a closely fought battle, but Peter narrowly took the win, and selected the keys to the Half-Done House.
