UL Certified and Miami-Dade County approved, Castle GreenGuard will serve as the base of operations for my Mega Construx Masters of the Universe once completed. I decided to start with the tower to the right of the entrance as you face the main castle. I figured if I couldn't get a circular tower started successfully, I didn't have any reason to go any further with the effort. Of course, the tower isn't independent of the rest of the structure. So eventually, I had to start on the outer walls. And there would come a time where 2"x1"x1"bricks weren't enough. I'm a little further than this image now but I guess I haven't taken pictures of the additional progress. Not certain where I will finish with the project but the plan is to have a full Castle Grayskull of some sort. Although I know I will take some liberties with the design. And while the green sheets are conveniently colored, I do plan on painting the whole thing to hide some of the sins of construction.
