I want a big shed, at least 12'x 9'. Does such a beast exsist? I wonder? Then I could spend my days there, drinking home brew from a chipped enamel mug and view the world through rose tinted Stadium Mk 4's...........sigh........
[Widey] I believe such a thing does exist, although it is usually described as a "house".
Seriously, though, (and this is probably not much help) the US company Tuff Shed manufacturers a bewildering variety of sheds (which they call "storage buildings"). Some very silly styles, though... 10'x30 loafing shed, anyone?
Indeed, widey. I possess one around that size myself. It's a steel construct erected on a concrete slab, so if you are looking for a rustic appearance I cannot help. Mine is about 7½ feet high, has a door (which helps) and a single window, half of which will slide to allow air into the thing, at the opposite end (covered in spider webs and their makers - both of which, by the way, are extras.)
