Though time has been scarce, I've been making little bits of progress on the blockhouse, whenever possible. I managed to get the dirt berm added around the first level, got the basic paint on it, and started adding the "extras.
The goofy thing on top is part of a solar panel array. There will be various bits of equipment on the roof of the first level, instruments and whatnot on the roof, and a collection of makeshift accommodations on the ground. Most of the work will be from styrene. More pix hopefully coming soon.
