In regards to the electrics, I put one group on a switch by the door that switches that group on and off. This way I am sure that everything is switched off before I go up.
Then around the workshop I drop two double sockets, the left ones are switched with the main switch, the others are on permanent. This way I can decide to leave things on or centrally switched off.
The centrally switched sockets run my lathe, mill, grinding and sanding, but it also includes the compressor, my music and fan extractor in the back for clearing the welding smoke. It works like a charm.
I like the look of your place, it looks like a great place to work. Your floor is definitely a lot better than mine is, it looks so smooth and level. Wow, great job.
