Hello, Emma ...
Back in the "old days", Playmobil made wonderful bases for their train stations. The bases came in pieces which joined together in whatever size you wanted to make. Some of these bases even came as add-ons so that it was possible to make sidewalks for a Playmobil town.
I've attached a few pictures of some of the sets, Maybe they're available on eBay?
Emma, your "Wilton Arms" is the most beautiful and creative building that I've ever seen made from the Victorian mansion building parts. Is it a shop? A pub? An inn? Or, a B&B? Whatever you've intended it to be, it's lovely. And, I'm going to try to make one with parts from my Victorian collection.
Thanks once again for sharing your imagination and giving us so many really great ideas!
All he best,
Richard
