Ok this is my experience of metal sheds.
Firstly, unless you mount them on a wooden floor they condensate really badly. So bad that your bikes get wet, you open the doors and it rains on you. I believe you can counter act this by sticking polystyrene tiles to the inside but it sounds like a huge faff to me.
Secondly, they look ok when first erected but dent really easily and look like crap a year in when they fade and show signs of rust.
Thirdly, they are so noisy. This can be a good thing because you’ll know when someone’s trying to rob you but if you have neighbours and you’re regularly in and out of the shed they’ll quite quickly get a bit pissed.
I wouldn’t buy another!
