Designing a Warhammer 40K Plasma Generator based on Dawn of War

I felt like making some buildings from the Dawn of War computer games. Scouting around the internet it seems that most people go for the Infantry Command or the Space Marine Chapel Barracks. Although both of these are nice, they are also huge and I would like to go for some smaller buildings. So I decided on the Plasma Generator. First step for this project was Sketchup. These are my first sketches. More news and info as I start cutting the foamboard.
