Actually I think the house got gutted but is actually still there.The house has been dismantled
Personally I would be very surprised if they rebooted it (again) due to the costs and declining ratings (not to mention Nine trashing the brand). OTOH, I would hope that if it did return, CBS would do live streams again, which is a perfect fit for today's social media like Twitter (in particular), which in turn, creates 24-hour buzz for the show.
Still ain't gonna hold my breath. I can't even watch BBUK any more because Channel 5 ruined it.
