dome building

[peter liddle]

been thinking of building a new observatory as a project this year,

thought of the slide off roof on a shed type which would be easy for me due to being in the building trade all my life, but also i am interested in the pod type with a rotating dome, starting with a thin plywood segmented dome then covered in GRP to waterproof and make the structure solid and stiffen it. wonder if anyone on here has attempted this type of observatory as a do it yourself project. ??

Have a look in the DIY section, there are several that have been built with GRP - either on its own or as a waterproofing layer over a lightweight structure.
