Hi Ed - the building looks just great: I agree with DeafNala about the bricks though! I build my scenery on a base of 3mm MDF board, It gives the opportunity to put in the ground floor, rubble and paving as well as providing a bit more stability to the whole construct.
What sort of templates are you after? I assume you mean for buildings. I use books on architecture and also the web. Try looking up timber frame buildings on Wikipedia, it will lead you to other interesting sites. The best thing is to study examples and just let your creativity go from there. BTW love the figures, especially the Ogre.
