need some advice re building a secure shed/bike store.
got a basic idea in my head, which is galvanised steel bike anchor concreted into the ground, then a 8ft x 6ft x 7ft shed with a sloping roof built around the anchor point.
I was thinking of a frame made from 4'' x 4'' timber with a marine ply inner skin and a external skin of treated decking boards.
I want to fit a inner door that opens in, and a outer door to open out. and if possible a window, with a drop down/lift up window cover that will work as a bench when lowered.
any pointers in any flaws in my plan will be greatly welcomed.
