After three months of hard work, The Blockheads' homes go up for auction; one team takes home a guaranteed $100,000.
Five excited teams meet Scotty Cam at HQ and are tasked with transforming five charming little blonde brick postwar houses into two-storey mansions in just 12 weeks.
The judges have a hard time deciding who takes out the $10,000 for kitchen and laundry week and the results cause friction between two houses.
It's the halfway mark of the build, and contestants have been working upstairs, going all out on their master bedrooms and walk-in robes.
Follows the teams as they take on their final upstairs bathrooms and re-do rooms challenge and the hardships that comes with it.
