My Roll-off Roof Observatory
In Feb 2011 we moved house and high on the agenda was to build a new roll-off roof observatory. I had built a similar observatory about 12 years ago at the previous house and it was still going strong when we moved, but the permanent nature of the observatory meant that it had to stay behind.

For my new observatory I have taken extensive photos of every step of construction which I have incorporated into a "how to build a roll-off roof observatory" document which can be found on my articles page. I estimate the cost is less than £500. The three photos below are the first and last in my sequence of construction photos that are included in the document. I estimate that I have at least 80 photos documenting the build.

A quick video demo of the roof is here.
