When planning your shop give a lot of thought and study to electrical capicity and circuits, placement of recepticles, and lighting. I painted the interior of my shop, ceiling and walls, semi-gloss white. If you can see better you will work better.
If tool mobility is necessary, give consideration to weight in your machine purchases. Yes. There are mobile bases, but even with a level and smooth floor, shoving around a 300 lb machine can get old - not to mention wear and tear on the old back.
