Yes this is THE most riveting thread posted today, I know 
We have a large adult bike with child's seat and a smart Pashley tricycle living in our tiny small back garden. We have a child's bike currently living in our living room. None of this is helpful to easy living or use.
We also have a shed filled with assorted crap the previous owners left us, some crap of our own and some things we would like to keep: pair of deck chairs, lawn mower, garden tools, gym trampoline, 4 x spare garden chairs, fold down 6' trestle table. The shed roof leaks and there are funnel shaped cobwebs in it (eeeeugh!). We also have a ladder is like to put in that appears to have take up residence in our bedroom.
So, I am keen to get rid of the shed and get a garden storage box that we can keep all the bikes in and our garden furniture and tools. The shed is average size and there is about half a metre space between it at the wall. Ideally I don't want it to be too deep because we might change the way round we have it but equally I'm sick of bloody stuff everywhere now.
Any suggestions?
