I've got a web magazine doing pretty durn good business and I'd like to get my office out of the spare bedroom of my VERY small house and into its own space. The spare bedroom needs to be turned back into a bedroom for guests ...! I need office space, desperately. Said space needs to be: 1. Easily air-conditioned. It gets horribly hot here in the summer -- 120 degrees isn't that unusual. 2. Reasonably secure against casual thieves. (Nothing will stop a determined thief.) 3. Able to survive violent summer thunderstorms reliably. We don't get tornados here; we do get some whopping big microbursts with 70-80mph winds at least once a year. 4. Look professional. I may have clients and various Important People visit. It doesn't have to be fancy, just neat and look "businesslike." 5. Big enough for two offices (myself and my SO), plus ideally a third room for a media room/library/records room so that I'm no longer in fear of dying by book avalanche ... A used singlewide mobile is out; the county won't let me put two "dwellings" on one lot. Otherwise, I'm looking for ideas and/or suggestions for manufacturers for prefab buildings.
