The four new teams arrive at The Block and it doesn't take long before they start lying to get the best house.

It has been a difficult week. And with only 24 hours to go before the children's rooms are unveiled, small delays can have enormous consequences for the four teams.

Tempers flare as teams steal each other's building materials and Brooke questions Peter Wolfkamp.

The teams are given a challenge that is designed to inspire a bit of artistic love. The teams all have to give an object a new life by repurposing it for something completely different, before they pass it on to a competing team.

The teams have to make up for hours because of four failed construction inspections. But when time gets the better of a team, the question is whether they will risk further delay or eventually take matters into their own hands.

All the hard work has left the couples exhausted, but they keep giving it their all. The couples are still incredibly competitive as each team tries to get ahead of the others.
