I already knew a lot of basic stuff (I was a plumber when I was going to college, and I worked electrical work in the military), but I learned how to: put up insulation; wire an entire house; plumb an entire house; hang kitchen cabinets; put down tile floors; install underground electrical service (yes, I pulled my own underground electrical feed 150 feet by hand through conduit); run a trencher and a mini-excavator to do final grading and install a plumbing service line; and probably other stuff.

Think mini studio apartments inside of a home.

I prefer the wandless/cordless 1" mini blind style. 

Have you looked into mini-splits?

It's about 200 sq.ft or less, so a mini-split would probably be an overkill.

Nothing fancy (mini-fridge, closet, desk, chair, bed) in each room. 

Sometimes they bring in a mini crane if they have to lift everything over the utility lines, 4-5 man crew, 2 trucks and if the town requires it. 

with outdoor mini kitchen. 

I had to do some minor renovation like converting the kitchen to a mini bar (taking the stove out) and removing the bathtub.

Although certain politicians here seem to be trying to make it a mini-California with their constant  efforts to ram Cali-style tenant-favored rules through the state legislature.
