Big Brother is certainly going out with a bang when the last ever series hit screens next week.
A carnival atmosphere will greet the contestants for the reality show, and housemates have been told to expect little privacy.
Many of the interior walls are made of transparent glass - including the bathroom that the dozen or so housemates will share.
"There are circus things and it's all slightly Alice in Wonderland," said commissioning editor David Williams.
"All the glass makes it feel lighter, but on the other hand you can never get away from anyone."
