Wow, those layouts are fantastic Churchill.
I have a good few Hovels buildings and they are great for Napoleonic through to WWII. If you are looking for some generic style buildings there is also PCM Games who trades on Ebay in the UK. Postage might seem high but he always does good discounts for multiple items. I'm pretty sure he does post worldwide. They are mainly resin and supplied painted but I usually put a bit of extra detail on them such as ivy, staining, etc. The roofs all lift off and most of them have removable levels too. Some of them are scratchbuilt with resin roof sections and I usually rebase these on thick plasticard or MDF for extra support. I'd post a photo if I could figure out how, but you could easily search for them on ebay UK.
