The contestants arrived at the warehouse for their latest challenge: to build a car port over and around a car. Two members from each team competed, with the first three to finish the job to the judges’ satisfaction winning the right to compete in the White Room Challenge. The Navy Team placed first, and were joined by the Sky Blue and Orange Teams. The White Room was luxury bathroom-themed, with the best room getting a $15,000 bathroom package. The pairs had five hours to finish their rooms, picking helpers to work through the night finishing the tiling. Michael and Jarrad most impressed the judges with their executive penthouse bathroom, while pre-challenge favourites the Orange Team struggled after Peter ran out of time to fully complete his dramatic vision.
