I've decided to build a RoR observatory, as is tradition. The site is gently sloping and has great north views, OK south, average easterly and a "personal" street light courtesy of "lovely" neighbour (in bortle 4) to the lower west. Of all the available locations I have available this is the best compromise - so many trees elsewhere. I intend to make the base structure from C15019 purlins, top hat battens and colorbond. The roof trusses I intend to make from 40x40 gal SHS welded, with top hat and colorbond. The rails to be more C15019. A suspended floor of form ply on more C15019. I am keeping it below 10 square meters and 2.4m tall to skip the council hoo-har. Being in South East Queensland means generally it needs to be very wind proof.
I wont bother making the east and west walls fold down. From the west the wall & roof can block the "street light" and to the east there's a big tree that I'm not allowed to cut down (booo!)
Running 240v & ethernet should be no problem.
Any and all suggestions or criticism sought most graciously, better to realise now than later
