re: If you were to build a new shop

Monty,

There are so many variables. What are your building codes? Here we can pour a slab on grade with only a footing around the edge. If we want wood floors, code makes us pour a 4-foot foundation wall (unless the building is under 160 square feet). Crawl spaces are notorious for rodent infestation (at least around here).

I’ve seen concrete shop floors with channels for dust collection. Dust collection doesn’t have to be “concreted” in. The channel can be closed with 2×10s or similar, that can be lifted out if a problem occurs. Take a look at this shop and read the comments for an idea. http://lumberjocks.com/WoodGal/workshop

I’ve also seen a shop with laminate installed over the concrete. http://lumberjocks.com/LesHastings/blog/10847

If I were building again (at my age), I’d probably want something on grade with a garage door for moving large items in and out, as well as a standard entrance door. Although I’m not totally excited about a concrete floor, the shoes (and orthotics) that I wear keep me from too much pain. I would probably put my heat in the floor and have an outdoor woodburner because we’re in a cold climate. (If your feet are warm, you’ll be warm.)

And I would definitely go with higher ceilings, at least 10 feet.

It ultimately rests on your preferences and your budget (and how intrusive your zoning department is). Be sure to keep us posted on your progress.
