@ Sakrison/Downloadable Building Kits
I purchased and built a Clever Model kit of a rural store (now out of business, and the building abandoned and overgrown) in French Camp, California that was near where I worked, and where I would occasionally buy an Eskimo Pie during my lunch hour just for an excuse to get off the plantation. Actually, it was a plantation, I worked for the county and the county jail and honor farm were just down the road from the building complex I worked in.
Anyway, the Clever Models store kit did a good job of capturing the look of the original. I keep it on my desk as a reminder of my past.
I am looking at another Clever Model, a water mill in Indiana. It looks similar to a couple of old water mill buildings that are still standing in SW Ohio.

Here are two more UK sites that offer paper buildings:
Wordsworth Model Railway
KINGSWAY MODELS - Home Page
Look at the websites carefully and you may find the free samples.
