I figured I'd share some of my construction pics. I cleaned out an area after looking for my best exposure in my yard. (not easy I live in the woods). This spot allowed decent view South and a view of the North Star. Instead of pouring cement. I bought 2x2 step stones from Home Depot. They will deliver, but I made two trips with my SUV. I got a load of sand and put a 4-6 inch bed under. Then leveled them and filled the seams with sand.
I notice a lot of light coming through the the dome/side wall area or is that my imagination.
