Four couples move into four identical apartments with little more than the clothes they are wearing.

They put themselves and their relationships to the test in the ultimate real estate challenge.

With equal-sized budgets they have just 12 weeks to out design, out decorate and out renovate each other... all just a stones throw away from Bondi Beach.

For 12 weeks, the four lucky couples, ADAM and FIONA, WARREN and GAVIN, AMITY and PHIL, and KYLIE and PAUL, must live in The Block with around-the-clock camera crews filming everything they do. Then the real climax of this challenge takes place

All four apartments prepare to go to auction!Whats even better, all four couples get to keep any of the profits they make from the sale.

The biggest winners are the couple who get the highest price as they also win the ultimate cash prize of $100,000. So the winners are decided by the toughest judges, you

The buying public.
