REFINERY
The refinery is not your typical building- more of a sprawling chunk of cover, with lots of pipes and tanks to hide behind. The pipes were made from a plastic Pants hangar (nice for T shaped instersections). Plastic hangars are great for pipes because you can add bends in them by heating them up without them kinking or melting away. I used plumbing solder, wire sheathing, and tube styrene for other kinds of pipes. The tanks are made from hotel shampoo bottles and asthma medication cartridges. Unlike most buildings, I primed this one with grey spray paint, painted base colors on, and grunged it up with lots of washes. Below is a shot of the refinery before being painted:
