'Big Brother' bosses want to keep the house open until 2013.
According to planning documents submitted to Hertsmere Council - which covers the area where the 'Big Brother' house is situated in Elstree Studios - executives on the show want to keep the iconic building there for three years, sparking rumours the series will continue in some capacity.
A spokesperson for the show revealed: "We are currently looking into a number of options for the site."
Councillors debated planning permission at the studios and decided to agree to the request.
Sources have previously suggested the show - which has been fronted by Davina Mccall for the last 10 years - may move from Channel 4 to Channel 5.
Meanwhile, insiders have claimed there may be one more series of 'Celebrity Big Brother' before the series is completely axed.
A source said: "Channel 4 has been really pleased with the ratings and the amount of coverage for this year's 'Big Brother' and 'Ultimate Big Brother', so they don't want to let it go just yet.
"It wall probably look a bit strange after everyone thought it would be the last we'd see of it on Channel 4 but it will be worth it financially for them to have one final run."
Among the celebrities to have taken part in the celebrity shows in the past are cage-fighter Alex Reid, music stars Coolio and Sisqo and actor Verne Troyer.
