I'm a contractor/consultant and 95% of the time I work in my own private office. In order to duplicate this arrangement it helps to have some sort of expertise/reputation such that your clients don't think they need to watch you work. If you worked for company A at one point in your career and left on good terms, you might do some part time contracting for them from home. If you worked for companies A, B and C and you can swing the same arrangement you're now a consultant.
