Looking for Shed - Specific Size Needed

Hi there!
I am looking for a shed for my mum and aunt, to store their two mobility scooters. As much as I would like to plop one down on my driveway, I doubt the council would allow that, which leaves a 5ftx10ft space in my back garden. The doorway would have to be as wide as possible, and on the short end of the shed, so the scooters can be driven in and parked one behind the other, which would give them enough room to get off them. It would also be a pent roof preferrably, as it will be in front of another shed and if it is an apex roof, any rain would be running onto the old shed's windows.


Unfortunately most of the sheds I've seen don't come in those specific dimensions, typically 6ft or wider. So if anyone has seen a shed that fits my requirements, I would be most grateful for a link or some info.
