If you know me well, you know that I like things to have a reason or purpose.  I definitely take function over aesthetic, but if you can mix the two in harmony, that's ideal.  To the point though, I would love a studio in the house, but I'd never be able to use it to it's full potential.  So i'd like it to have it's own entrance and have it run as a business.  There's probably some way I could take advantage of running a business out of my home come tax time too.  If I could find someone that would be willing to run it for 85% of the profit, I think it could work out well.  It'd be nice to open up the house to musicians as well.
