Ah ok that's interesting because I also have a modest shed which is absolutely full of kids toys and rubbish for the tip when they open again!
Can you link me please?
Thanks
I bought mine quite some time ago from BPS via Amazon on sale, but on the BPS website it's the 10 rung 3 section combination ladder. 6.26 metres open and 2.86 metres closed.
They do a 6 metre ladder that closes to 2.5 metres if you really need that extra half metre to be able to store it. They are a bit fat when folded up, so you might need to take that into account.
I have a 3 metre shed with a door in the end, so I can just walk my ladder into the door and stand it on it's side against the wall of the shed.
Make sure you get one with the wide feet, it really adds a lot to the stability.
