Producers say Big Brother 7 will be "more twisted than ever."
The house's interior walls will all be made out of glass, and will shrink in size, despite having to hold just under twenty people. The one communal bathroom will contain a shower, bath and two urinals.
Big Brother's Little Brother presenter Dermot O'Leary explained: "[Housemates will not find lasting fame. [They'll] make a bit of money, people will like [them] and people will hate [them] and that's it."
Producer Claire O'Donohoe commented: "Cosy isn't the word. There really is nowhere to hide. It will be more twisted than ever
