I have this one. I put it up by myself yesterday, and it was still there this morning (apart from the piece that is missing from the door)
I paid a little extra, because I loathe roll up doors. This ones seems ok, but the gutters (also an important feature for me) are really low, and a standard water butt is a foot taller than they are. I haven’t staked mine down, but weighed it down with sandbags full of stones so I can move it next year if I don’t want to keep it where it is.
I haven’t put any staging in it. I will most likely just plant tomatoes, peppers and chillies straight into a bed down each side and a loofah to scramble over the ceiling. I was planning a couple of aubergines, too, but I can’t find any plants.
