This week the teams don't only have to renovate but build their master bedroom, en-suite and walk in robe, a massive forty five square metres. It's the largest area Block contestants have ever attempted to be renovate in one week.

The pressure of finishing the biggest room ever in Block history is starting to get to the couples. It's a hive of activity in four of the houses but one team is three days behind and it looks like they won't finish.
