Compare the size of the old garden (BB3) tto new garden (CBB11)
 

Does anyone have aerial shots of both.

so from BB3 (which was huge) up to CBB8 (whih used the same shape as years before).

I know they literally only use half the space and would like to see how much bigger it could be especially for the big revamp this summer.

yep but it change a lot

1st one from 2011, second one from 2003.

Thats literally half the space used then in current BB

They ripped the back down and rebuilt it for BB9

The old Garden was demolished in 2008 before Big Brother 9. The new back restricts what they can actually do with the back of the House.

good point

The roof of the back is raised slightly and contains loads of electrics and solar stuff, it can't be taken down i don't think.

as it got more stuff in it the more it shrinks

I think id rather have a smaller garden and bigger house

It's all of it, as has been said they demolished and rebuilt that part for BB9, the large task room and bathroom take up the extra space BB3's had now.
