My advice would be for a guy in Hawaii: Make sure its on top of a hill and as far away from a volcano as possible. Also have a separate lavatory and washroom (mudroom) so your significant other isn't nagging you about dragging work clothes into the "clean" house. Have plenty of air drops and recepticles like every 6 feet along the wall. Have the air compressor outside of the workspace so that it won't rack your brain when it's running. Put drains in the slabs so that you avoid wet floors as much as possible.
I would add an extra shipping container (20' or 40' ideally) so that you have somewhere to store all of your future project extras and spare parts. Make sure you have plenty of electrical service amperage! Then add projects and enjoy!!!
