After saying farewell to Kelly, it was back to business as usual in The Renovators warehouse. Brendan introduced the next challenge – ‘Garden Mania’ – in which teams would select a garden theme at random and have five hours to transform a 6x6 metre patch of bare earth into a landscaped wonder. Guest judging the challenge was gardening legend Don Burke and award-winning landscape designer Daniel Baffsky. After a thorough assessment of the results the judges decided that the Orange Team’s Australian Costal Garden and the Grey Team’s Australian Dessert Garden were the standouts, giving the overall win and the Working Bee prize to the Greys. The Mediterranean Garden was considered the most lacking, leaving the Khaki Team facing an Elimination Challenge.
