This piece is based on a Three- Mile Island nuclear power plant model. This kit is also "N" scale like the Factory. The main building of the kit is as it came, but the dome was cut nearly in half to accommodate a repair gantry. Most of the other parts were left out and added to the (at that time) tiny bits box.
A hill was cut out of 3/4" foam and made to fit snugly against the side of the building and platform. I was trying to make it look like it was built on the side of a hill. A ramp was also made out of foam leading up to the repair bay dome.
The piece was primed white. The stone and asphalt areas were painted black and drybrushed to white. The bay interior was drybrushed silver. The bay and building were then given a rusty colored wash and a purplish wash (which turned out very purple in these pictures.) The dome exterior was painted an olive drab green and highlighted with a lighter green. The floor of the bay was painted gray with a spotty white highlight applied. Wash was added to the floor to look like oil and chemical spills.
The hills and ground were flocked and some lichen was used as bushes.
