I utilised garage door hardware to fabricate a two level roof for the office section and OTA section of the approx 3m by 6m obs. The roof of the obs section rolls over the office section, and the rails that would support it when closed simply lift out offering unfettered view. Easily operated by hand.
In my instance, I tried to maximise my pier height for a better view, and built a raised floor section around the pier. Allowing underfloor cabling. I put in a simple double glazed window between the rooms so I could watch what was happening, and a thermal curtain in the doorway between to accommodate the cold Canberra nights. It worked very well. Utilised colourbond materials to blend in with existing garden sheds in the Canberra area.
