Five rooms in the challenge apartment are completed. The judges decide which team has the advantage on auction day. First place receives $20,000 off their reserve price, second place $15,000 and third place $10,000 off their reserves.
Four or five couples renovate a derelict apartment block in Melbourne, Victoria, with each couple renovating a separate apartment over a period of 12 weeks and within the budget set by the show's producers. The apartments are 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. Season four saw television personality Shelley Craft join Scott Cam in hosting the show.
