Instead of demolishing an ancient portacabin we renovated it by cladding with reclaimed metal sheets. It worked and the cabin is now weather proof and very cosy. I use it as a workshop for my spinning and knitting and also as a store for the sheep's fleeces I work with. I love my shed and spend a lot of time there.
I love this site and its great to know there are lots more 'sheddies' out there.
