Hey there's nothing wrong with shed keeping! I've got a 6 year old that, as soon as he sees a shed in any of the tubs he asks, "can we keep that one?" Of course the second question always is "is there a big stinky poop inside that shed?" (geeze you get one stinky prezzie in a shed roll, the kid is scarred for life or something LOL)

Congrats on the nice shed!
