When housemates head down the sweeping blue staircase on Thursday’s live launch show, they will see a wall of colourful doors.

They will be made to wait until later in the series when some will open to reveal secret rooms.

The wannabes will also be shocked as there is no swimming pool or hot tub visible. But bosses teased if people look hard enough, they may find one.

There is also a barred “prison” in the garden for anyone who misbehaves.

The house also has an ecotheme, with the dining chairs made from old bike saddles.

And there is a bicycle in the brightly coloured bedroom which the newbies need to ride to provide electricity.

The wannabes will have to work a wheel to get the water for a shower, which must be taken outside.

Dirty clothes will be washed by hand and go through a mangle and housemates will grow their own vegetables.

Indoors, there are shelves of foreign books in the bedroom, while in the lounge is a bank of TV sets to remind the gang they are being watched 24-7.

Big Brother host Emma Willis, 37, said: “I’ve been inside the house and it’s bloody awesome. The best house yet.”
