Bike sheds - Any recommendations?

[Matt106]

The time has come to house my pride and joy in a wooden shed....I've just moved house and have no indoor space or garage so the only option is a shed in the garden.

I've got very limited space so looking for something aprox 6x3 but can go a little bigger. It also needs to be a half sized style shed so I'd say 5ft high?

I've come across a couple that fit within my budget of £250 however I'm worried about the flimsy doors -

I'll be reinforcing whatever I buy to a certain extent but would like it to be safe-ish to start with. I'll also be investing in the usual ground anchor, chains, locks and alarm system.

Any pointers would be good as it's hard to tell looking at photos online.
