Lets see, too many things to list really but here is some food for thought
1. Enough outlets and capacity on the electric service to run everything without even putting a strain on the system. Plan on people running more than one machine at once, and the overdraw of a motor as it kicks on.
2. Lighting. Lots and lots of overhead lighting. Not so much high wattage, as a large number of lights. Moderate light from every angle is
MUCH better than strong lighting right in your face or from behind you etc. No shadows even if your standing next to a machine or facing a different way than usual.
3.Lots of room. Bench space dedicated to just handwork like assembly and layout stuff,preferably with a 1/2" lip around the edge so small parts can't roll off.
Its really a bear to slide machines in and out of the way as you move back and forth, so it would be nice if all or most had their own work space.
4. Windows, Large sliding/garage doors. If the weather is nice out, its great to get some fresh air into the shop. They can also be a welcome source of light.
5. Concrete floor with proper pitch to drain, either out a door or through a grate in the floor. With the type of machinery your using your going to accumulate a large amount of grit,grease and grime. It would be nice to have the option of blasting things out once a year with a pressure washer or hose. Not to mention all the buckets of water around for dipping. If you spill one, it would just drain away rather than you having to clean it up.
6. Exhaust fan or fans. Gives you the ability to clear the shop of harmful fumes and dust. You probably wear a respirator but your eventually going to want to take it off. Also helps cool things off.
7. Storage space. Don't eat up your shop space trying to store steel, spare sawblades, belts etc. I'd have an ajoining store room with racks or drawers for everything that doesn't need to be immediately at hand in the shop.
8. A clean room/area . Something partitioned off or a seperate room for applying handle finishes, sheathmaking etc. Somewhere that you don't have to worry about picking up grit or things getting scratched or knocked around.
9. This is working out to be a pretty damn big place, so a personalized golf cart for trips from one end to the other
