I many years ago did the below based at the old Dreamworld concept. House was in 3 stages:
It was created using the plan from the BB03 house and extensions to the compound from its 2003 state are shown in red.
The Kitchen & Dining is something that hasn't been done in Australia.
They are split level. The kitchen going up, and the dining room going down (with the bathroom on the same level) by half the height of an ordinary wall.
This allows for a camera run to be below the bench, and also gives the housemates the ability to look down on the dining room if they are in the kitchen.
The water feature has a hidden camera in it that isn't visible to the housemates, giving a different view of the housemates to the viewers.
The maze outside is covered at first but is revealed when the two bedrooms are joined as one. Off that maze is a new version of the Chill Out Room that we saw in BB07. This Chill Out Room Sits on top of the compounds camera run so it’s almost like a cubby house that was done in 2014.
The exit for the housemates when they are evicted is back and on the side of the compound. This time having a switchable glass window that the housemates left in the house can see the housemate leaving the compound.
Please ignore the red dotted lines going through half of the houseplan, that is just an original indicator of where the actual interior shed starts.
Another thing, the little room on the bedroom once its joined (Also labelled in the split stage as CWC) is a central Water Cubical. 
The rest is all pretty self explanatory, but if you have any questions ask away
