I've put question marks where I'm not sure there's a room. I guess the diary room is accessed via the vestibule, and that there is a store room off of the kitchen, and a toilet just off of the lounge.
There's 3 doors in the garden. One to a toilet, one to a bedroom? And one to an outside shower?
The rest I think is pretty accurate, though.
Of course, any insiders please correct me
