You have got your terminology wrong, that's definitely a workshop NOT a garage, me and SWMBO argue about my workshop, it has never had the car parked in there therefore it's a WORKSHOP and always has been.
By the way yours is far too clean, I would never post pictures of my workshop its constantly messy!!!
very similar to my workshop. Converted integral single garage. I have a double socket on the wall. from it I run 2x 6 gang plug boards. Into these I plug everything. This looks unsafe but I only run one machine at anyone time so it's not really that dangerous. Just don't switch everything on at once.
