Hand your keys to five rival couples, then fly interstate and gut somebody else's living room. That trade is the premise of this Seven Network competition, which began in 2013.

Six teams of two, one drawn from each Australian state, each put their own house up for a week. The other teams move in, strip the rooms back and rebuild them to a brief, working against a clock and a fixed budget. The owners sit it out somewhere else with no say in the paint, the layout, or the feature wall waiting for them at the reveal.

Johanna Griggs fronts the series. Wendy Moore, Drew Heath and Carolyn Burns-McCrave walk the finished rooms and score them, and the teams score each other as well, so the leaderboard doubles as a running argument about taste and effort. The highest total across the season takes the top prize: the mortgage on that team's home, paid off.

The format comes from the producers of My Kitchen Rules, and the family resemblance shows the moment contestants start marking their rivals. Reveals land harder here than on a standard build show, because the person standing in the doorway owns the place and picked none of it. Good company if you watch renovation television for the people rather than the splashbacks.
