Bob, my garage is the way we enter the house 99.9% of the time; you walk up two steps then you're in a mudroom, then the kitchen. While I like to think I still have a great sense of smell, but the fact is I'm somewhat inured to the chemical-type scents of resin and bondo, brake cleaner, lacquer thinners, etc. My wife isn't (thankfully). I'd avoid doing any of this kind of (stinky) work in the winter months, but now I can work with garage doors open, it's less of an issue.
That said, the ventilation ideas you guys have suggested are excellent. If I were ever to get that dream workshop (not complaining about what I have**), heating, A/V and ventilation would all be basic, prime concerns.
** A year or so ago I found this website, retro-rides.org, out of the UK. There are some incredible projects here, and some less so, but often the cars being restored are admirable for being so prosaic. But the point I want to make here is a reminder of how good (most of us) have it here in North America; "over-there" space is so constrained, but you see guys doing serious work in their driveways or tiny little sheds in which we might store our push mowers.

If you're looking for some good education, may I recommend any posts by "grumpnortherner" or "glenanderson". Two examples:

I still have a hankering for "Series" Land Rover, preferably an 88" SWB model, although driving one would likely put me in a wheelchair, and I have no interest in building a non-metric set of tools. But was there ever a more honest and capable family of machines? Only the air-cooled VW family comes close in my mind.
