I do! I just bought a house a few months ago and currently its just my wife and I in a 3 bedroom that is much bigger than any house either of us have lived in before so we have lots of space. I currently have the downstairs bedroom all to my music. I can fit my whole band in there during practice and its a huge step up from our previous practice space as it has windows. I also get to have all my gear right next to my desk, on which I currently have my Macbook hooked into a 23" monitor which makes recording and the like very nice.
Some pics:
I have since added blinds (will be doing curtains soon) and some monitors at my desk, though I still pretty much only use headphones. Oh, and a rug
Also, the panels on the walls are home made sound absorption. The room is very very echo-y on its own and these helped a lot. I will be adding some to the ceiling and around the doors soon as well. If you want details of what I did I can give them. I think all of them cost me a total of maybe $80 to make.
