Hi Peter,thanks for the tips!
My location dictate the orientation of the building. NW-SE to follow fence-line and the fact I reluctant to cut trees to help my hobby.
My view is limited low to the horizon anyway, happy to concentrate to the sharper part of the sky
Re roof, I'm thinking of skillion stile to keep it simple... but not sure of the look and waterproofing issues. Will see, all flexible at this stage.
Part of the 3x5 building is the control corner... I like to be there
And in Australia/Adelaide the temp is not drop below 3C-ish too often. That's not cold, -20C is
Cheers,
Mick
