Well this is weak sauce! I just found out that I can't build a green house in MY OWN BACKYARD.
Well I live in a gated community. Apparently I can't have any structure in my backyard that is visible from the street. Since my backyard is huge and is shaped like an "L" the place I would put a green house would be seen from the street . So the place that is perfect for a green house, and I mean literally perfect, I can't use.
So I think I have a plan. Since no structure can be visible. I'll buy some huge trees pronly cherry or something nice. Then build the foundation and plant the trees around it to obscure the view of the green house. Shouldn't be to hard, I only want o make it 10x15 or so. I don't know I'll have to talk to some neighbors that have been living here longer to see if I can get away with that.
