This project started as an Ertl dealership building which I used to make a mini display. This was a relatively simple project, I started with a piece of luan board 36"x48",  Next, I painted the area where the building will set with gray primer , then traced around the building and masked that area off. To make the paved areas, I used black textured paint for the base coat, then added a light coat of flat black. For the grass and gravel areas I brushed on a thick coat of white glue, then added the turf and gravel. I allowed 24 hrs drying time between each step.  I glued the building together and covered the joints with styrene strips.  For detail painting I used a thin sheet of styrene for the floor in the parts dept, the shop floor is the painted base board. Some of the signs inside are decals and some I just cut out of magazine ads. I set this up for a farm equipment dealership, but for this site I used trucks for display pieces. The interior detail pieces are several different scales, as we all know 1/64 details are not easy to find. Some of the detail pieces that came with the set are actually closer to 1/48. I have found that with proper placement you can mix different scales and come up with a unique display.  Hope you enjoy!!

Some of the details in this area came with the building set, the office furniture is 1/48 scale Plastruct products. the vending machines are 1/64 from an S scale train supplier. The truck tires look a little big in this shot but they are actually 1/64 scale.

The large detail parts are attached to the building, this makes it easier to place the small detail parts and vehicles on the board and then set the building on.
