I built a 600 SF shop in the back yard, but it's fairly cluttered up right now.
To the OP--I don't think it's likely you'll find a better answer than having a shop where you live (SFH, or condo with garage). Just being able to walk out there any time and do a project or fix something is much better than having to make a pre-planned trip somewhere else. If the yard maintenance of a SFH is getting you down (esp when traveling), you could hire someone to do that and it would be cheaper than renting shop space somewhere else.
