So, Burbank Boulevard has no malls, or addresses for that matter, in the 9000s.
So...
Here's my idea for '9000 boulevard'.
4400-10406 blvd with buy more/orange orange/large mart.
yes, I did the car park.
And if you think plot itself (not it's placement in burbank) wrong, well, aside from one or two liberties with simplifying the damn road part of the car park, I just screenshotted the actual place used for exterior shots of the BM/OO, and did the MS Paint stuff over it... then redid the car park because it's layout is confusing.
yes, the parking spaces are diagonal.
And if you think the orientation is wrong blablabla, the store is south-facing anyway, and supposedly to be visible from the road itself so store is on northside of the road.
so.. how about castle?
well...
Buy more
Small one - season 2, and larger one season 3/4/5 (with the original tunnels obviously cut off to the Orange Orange, given they kinda dropped the yoghurt store as an entry point from season 3. actual shape/etc of castle itself is just my imagination. tunnel to based on the bit when Morgan found out. Should be obvious what the two little areas to castle are (along with the tiny one) ... aka the bit where both connect is the hub room, the strip is that tiny room along it, one is the armoury, and one is a cell block.
The Expanded one is just a bit of nonsense really, given we aren't given a decent idea of it's actual layout. And with that ridiculous network of vents, and how about that the tunnels morgan used had various turns that only ever seemed to be more ridiculously long tunnels? yeah. So this one.
And yes, this puts castle as beneath the parking lot. Car park. whatever you want to call it.
