Whilst browsing the Big Brother section of the TV3 website I found an official house plan... except the pool looks a bit effed...
Pretty damned close, my friend. Top marks for perception!It is about time...
So I wasn't too far off... I knew there was a 'kink' in the power room/task room corridor of some sort but couldn't get the specifics til now. This also answers where the upstairs access is for crew.

EDIT: Looking at it further, this must be a 'work in progress' house plan - the pool shape is more elaborate, the treehouse isn't quite the same and the placement of the bed and television in the sanctuary is also different.
If you look at the plan that was shown during ACA with TheBlock contestants "bali-fying" the captain's quarters, the pool looks the same as the NZ TV3 pool.Wonder if TV3 just copied Marquesite - strange how it's so right yet they get the pool so wrong.
