If you can put the welding table by the garage door, and preferably one outside too, then every chance you get do your grinding and welding outside, saves a bunch of mess and grit in the shop.
My garage has a floor drain, which is OK in the winter when the snow melts off the car. But if I were to build a garage I think a more level floor to roll stuff around on would be better, and sacrifice the floor drain.
Outlets above workbench height and every 8' or so would be good, on numerous different circuits.
Go ahead and run the 220V wire in the ceiling (or floor) for a lift.
Plenty of lights and paint the walls some sort of white to help too.
Think of storage. My solution was some pallet racking on the back wall and a forklift to load and unload it. Great for storing engines, transmissions, and other big heavy and bulky stuff, even have the the cab for the 48 on the shelf right now.
Haven't installed it yet, but I'll try the air compressor in a lean-to shed outside. It can be really aggravating to have it in the shop.
