I'm green with envy.
I have a spare room at the moment which is my study, but my largest Playmobil-friendly table surface is a fraction of the space you have, and I can't even fit all the castle parts I have on it, let alone a village and a forest as well!
It's great to see such a layout, and be able to recognise Steck, System-X, and and a lot of the sets and figures in use.
You've spurred me into action. My castle, one assembled, became a dump for loose Playmobil bits and figures, but yesterday I started to tidy up, re-arrange, and think about the whole set up. I'll say no more now, but I've started planning my historical context and background, and hope to have things better arranged soon.
