All right, this is the kind of writer-porn I officially disapprove of, but I admit that this collection of pictures of writers' work rooms on The Guardian Book page is somewhat fascinating (scroll down, in the bar on the right). I think John Mortimer's is the only room I could get any work done in:
See that little liquor shelf under the window? Quite an innovation. I also like all the postcards and goodies to look at, the brass desklamp, and the nice solid wooden desk.

I'd have trouble working at Nicola Barker's place. I'd keep wondering how much I could get for all those knick-knacks on eBay:
I don't know Barker's work at all, but I'd guess that it's rather baroque.
I like a smallish room, I like to face a window, I like a heavy desk. I wonder if I'm trying to recreate my childhood bedroom, or maybe my college dorm room? A good room should allow your mind to leave it.
