Thanks Fastolfrus, that's really helpfull!
I will drop him a line, I think there is a severe lack of "modern" as in now rather than near future, UK buildings in 28mm scale.
Thinks like Victorian,Georgian and more modern buildings can be mixed easily ( Just look at any UK town or city) but only seem available in HO and oo in any quanitity.
I'm sure there's a good market for 28mm stuff!
