The four couples are introduced and move into The Block. They randomly draw keys to discover their assigned flat. Everyone is shocked to discover the level of devastation in each apartment. After ripping out horrible old carpets to discover hardwood, one couple finds weak boards...and then termites. An ongoing issue with water leaking from an upstairs apartment creates strife.

Upstairs noise becomes a major issue for the downstairs tenants as there is no carpet or insulation to muffle it. All the couples meet for a body corporate (homeowner's association) resulting in a coup.

Termites are discovered throughout! The tenants begin to spy on each other and renovation turns into reconstruction as floorplans begin to change.

Couples work hard to complete their second room for judging. More division between the upstairs and downstairs tenant develops. Poor communication between the tenants results in near electrocution.

Phil is caught spying on his downstairs neighbour and Paul and Kylie are living without any running water. The judge is back to award a prize for the winning room.

It's room delivery number three and big prize money at stake. After six weeks of hard labour everyone is scheming and no one is prepared to back down. Arguments erupt as Fiona and Adam ask to move their hot water system.

Emotions run high as all the contestants juggle renovation with their day job responsibilities. They all take a break from the hard work to see Amity launch her singing career at a bar around the corner.

Room four winners are revealed. The front garden and attic spaces are still a point of contention as every dollar must be accounted. Amity's dream of becoming a recording artist move closer to reality.

Work on the final rooms leaps ahead. A couple switches up their floorplan by redoing a room they'd already completed. The couples pull out all the stops.

Judgement on the last room at last. Tempers break and one couple threatens to leave the competition.

Despite the need to cooperate to complete the tasks for charity, one team completely unravels while a trip to the pub becomes a point of contention for the other. One team show much better organization than the other. One team fails to deliver the first four rooms on time, even after negotiating an extension.

This season finale covers auction day and the winners of the real estate challenge.
