Now that I have a cellar space, I have my stash of building materials out of the way. What I would really love to do, is build my own house from recycled materials. In my London warehouse I used quite a good deal of recycles. It's amazing how it all turns out and some times even better than what you might afford to purchase as a finished product.
Keeping the studio tidy is an ongoing process for me. I'm going to have a decent purge soon.
Having a cellar is a big advantage. As long as its not like here, where its more like some dark moist dungeons underneath. But we still have a decent amount of space... at least one advantage of our "Burg" ;-)
