Just released  is a series 6 new low relief houses to build. They are really easy to assemble using foam core or core flute from a local art store or hardware DIY. I paid less than $10 for a giant sheet and it made several buildings. They are extremely sturdy and very realistically weathered. Each building is less than $10, but right now if you buy all 6 you pay only $19.95 (a 49% SAVINGS) Here is the link to the special offer http://www.modelbuildings.org/low-relief-buildings-C.html
