Build your own Lincoln SitesIn honor of the 2009 Bicentennial of Abraham Lincoln's birth you can now Build Your Own HO-scale cardboard models of actual historic buildings associated with Abraham Lincoln. Funded by the Illinois Abraham Lincoln Bicentennial Commission in association with Old State Capitol Foundation and the Illinois Historic Preservation Agency, the downloadable model parts for ten Lincoln Site models are available.
then there is "Build your own Main Street"
Replace the windows and doors w/Grandt Line etc, print out extra sheets of cardstock to 3d the surface ..
If you don't believe that cardstock look 'good enough' .. take a look at the buildings (O scale) that Troels Kirk builds for his layout .. http://coastline.no13.se/ .. his models/modeling sets a very high standard ..
His Tesdorf Weavery for example .. like most of his buildings, built form mostly cardboard and paper ..
