Miines in my celler but what i did could be applyed you a shed, i insulated the outside wall and inside wall (10cm outside 5cm inside 10cm celing) what youll have to do seeing as yours is outside also put a minimum of 10cm under your shed too (i used Sturodur, dont know what its called in english but its a very hard polystyrene). Make sure youve got an extra fuse box for your shed. Now my shelving is made from untreated wood, dont seal the wood as wood works and if its sealed and a crack and water gets in, it has no way out so will start to rot the wood from the inside.
