The original format of this reality TV series featured four couples with a prior relationship renovating a derelict apartment block in the Sydney suburb of Bondi, with each couple renovating a separate apartment. The apartments were then sold at auction, with each couple keeping any profit made above a set reserve price and the couple with the highest profit winning a A$100,000 prize. The current format is relatively the same except the series usually features five couples, it is mainly based in Melbourne suburbs and the budget is $100,000+.
