You're right, as is Boily, the Father Ted 'small/far away' thing could work
The problem is space - the building stands on a board with just a few inches around it, so there isn't enough space for the small/faraway perspective solution.
I often wonder what is to become of the model in the future - I don't really have room for it in my house, and it would be a very outing thing to have around, I'd have to change the name and lose the gerbils!
So if it sat on a bigger base, it could have the microbrewery and the beer garden and a pond and the trees full of tree kangaroos and sloths - oh hello knittedsloth, long time no see! But for now, it is what it is, and the littler little people will populate some other, smaller building..
