|Systema Gaming Base-0 Habitat Unit 2.|
|Removable roof of course. The windows you could either keep covered or pop them open as you please.|
|Bottom building with the little patio. The railings and ramp are all removable so you can customize the look.|
|You can see the underside of the roof and the girders and tabs that keep it in place. Ladder is of course removable.|
|...or building low.|
The handrails are easily movable, just like the ladders and the roofs. In fact they are almost too loose, but I suppose that is better than being stuck on too hard so you'd damage the paint when moving them. That's pretty much it I guess.
Next up will be the Communications Unit!
