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.

Nice shed, I wish I had room for a shed that big.

No A/C?

What's the point of running fiber to such a small building? Going to be your new jack shack?
