If you like the clean, uncluttered and peaceful look of DPDAN's work space, it's a great model to get inspired by.
Back in march of this year, I started a thread asking people to describe their home studio set-ups, and a number of people ended up posting pictures.
Here's a link to that thread, where you'll see pictures of Tom Hopkins' "Star Ship Enterprise" approach to home studio design, Gunther's tidy and serious looking work space, my somewhat whacky and "junky" playroom/studio - and several other home studios. Could be another source of inspiration for you:
Good luck with the project!(rbowser)
