Buildings for OO layout

I spotted the Knightwing Mine Top Buildings whilst browsing their website the other day, and started thinking about buildings for the small OO layout I was planning. I'm not sure the Knightwing buildings (which were originally produced by Heljan as "Tucson Silver Mine" are quite what I want, they feel a bit too old (and American) for my purposes. I'll keep a look out for other kits but I might just scratch build something, maybe a bit like this sand loader or this silica sand loader, thought neither is quite like what I'm after.
