I started to build my observatory in the fall 2005 and in the summer 2006 I finished. I will upload a plan for the building once in the future. Here is some pictures from the building site, when the foundation/base was build it looked like chaos.

My oldest son Rasmus helping with making the concrete.
The rib for the dome is marked by a caliper/divider.
My two youngest sons Jakob and Emil helping to glue the rib.
Now are the rib assembled and waiting for the veneer to be mounted.
My father-in-law helped with the roof. And it did also suceed to move the doome around.
