I was looking for some information on the design and manufacture of observatories. I came across some plans to build this observatory. Even though this is not a traditional dome roof observatory it does look like a good option. If you are handy with a saw and comfortable doing a spot of DIY there are comprehensive instructions below.
The plans come from a site run by Keith Ehren,a professional software Architect. He has over 25 years experience of designing and implementing software systems for government and commercial clients. He developed AstroWorkBench applications and has released them as freeware for other astronomers. If you want to look at his site you can find it here.
Rather comprehensive plans for the build can be found by clicking here:
