Instead of voting for an eviction in just under a week's time, audiences tuning into the show will be asked to choose one person to move in with the five new housemates.
The contestant chosen for eviction will exit to the new house though the diary room, into a new environment completely different from the original 'Big Brother' house.
The housemate who is voted out on Friday will be completely unaware of the secret annexe, until asked to enter after eviction on Friday. The five new housemates in the second house will also be unaware of their arrival.
On Friday night, Lisa became the fifth contestant to be evicted from the house. She had been up for the vote along with Imogen, Mikey and Nikki.
It will be the third year in a row that 'Big Brother' has had a secret house. Last year, Orlaith, Kinga and Eugene spent time hidden away before being chosen by Makosi to enter the house proper while Kinga was kicked out.
