I really would like to have a Fun-Shed like Lauren Liess at Pure Style Home has made for her yard. More on fun sheds at Pure Style Home.
Apex sheds, garden sheds at Spirit Sheds and a great list of links for sheds here. Shackletons, garden sheds look good. Storage Sheds & Garage, a blog dedicated to sheds! Cabins exceptional.
As luck would have it, I found this I love sheds link at Sophie's lovely blog.
