It started as an 18 egg carton. I always looked at it upside down as some sort of sci fi element. I would say that any kind of industrial packaging can be made into sci-fi terrain. And I'll show you in future updates!
Anyway, gator board was used for the bulking up, with plastruct I, H, truss and a set of stairs, and diamond plate. wall caps are from old warhammer chaos spell cards ( a great source of construction card), and the railings are wire screen. Additional valves, screens, hand wheels and corner lights are from a visit to the lego store at Disney. Fill up a bucket of parts that you pick. I have 2 boxes full of random detailing parts that are great.
Also is a couple of pics of my Armorcast soda can tanks. Ready to be painted as well. Armorcast makes some great resin terrain at a reasonmable price.
