Monday's episode of House Rules saw the remaining teams tasked with overhauling Lisa and Andy's backyard, which led to some serious tension.
The backyard was divided into three areas, and this time it was up to the teams to choose the zone they wanted, with both Shayn and Carly, and Mat and Tim all vying for the outdoor lounge area.
After an awkward confrontation, Tim offered a potential solution to the dilemma, but Carly, 31, still wasn't happy, branding it 'a d**k move'.
