I wish to build a viewing platform by tomorrow, in time to watch the Rugby World Cup opening. Although it's on a steep cliff the platform will be less than 1 metre from the ground. I'd like a roof on it. The roof area will be less than 10 square metres therefore doesn't need a permit. I imagine it will be 3 metres long by 1.2 metres wide or thereabouts - enough for four chairs. The handrail on front will be extra wide and do for a table. I'll need to dig into the sandstone cliff and put a retaining wall above and below. I have enough ground-treated timber and roofing iron to do the job.
Once I've built it I have a feeling that I will have missed out something important. I'll have 12 volt electric lights, and a cordless phone. What have I forgotten? A fridge would not be needed. Maybe CCTV to see who's at my front door.
