15+ years ago not only did I want to do that. But also run a 25pair copper (110 punch down.) , coax, and a backup wireless PTP. Just for fun. But, as time went on. I have a shed now. :) That and mostly places only use fiber and some sort of wireless if they can't use fiber. But, I was looking at playing with old stuff like HDSL, Digital PBX, Moca, etc etc.
Just finished a 10X16 using Kings as well. I did the same, made some adjustments, added a little roof height. I ran 220 to it as well, my plan is to drop a mini split into it so I can use it as a wood working shop in the winter (and keep it cool in the summer) Ended up going with 2x6 so I could better insulate i. I'm hoping the 2x6 helps the roof hold up in the winter, I'm up in AK so snow loads are an issue. yours looks incredible though.
