tHIS IS ONE GREAT MODEL. I spent about 16 hours working onit so far (it's complete according to the insttions, however I'm thinking of cutting out a window and putting anoter freight door withloading dock on the backside. As far as the basic model is concerned it is an awful lot of fun and the roof lines make it very intersting when complete. I'm using it as a plumbing supply house ,but it could be use as almost any small business.Te instruction sheet is one of the best I've ever ran into, they are written clearly and the diagrams are large and clear. If you could use a nice 2x3 or so this is one you should get.
