Even though it is direct burry, it is ran in grey electrical PVC conduit including in the basement of the house.
I also ran a coax cable out there so my shop part also has cable TV. No water or plumbing though.
Hey, that's a really nice pole barn. I built a 40 foot pole barn years ago and it is without a doubt the best addition we ever did to the property. My wife loves it.
Here's some tricks I learned after using the pole barn for a few decades...., and also a hinto on how I got my wife to not only approve but participate in the project from design to finish.
That's the most important thing, so it comes first....
Storage: The trick for wifely approval was to design and build in dedicated storage for house stuff into the pole barn. We built upstairs storage areas on both ends of the pole barn about 12 feet deep and spanning the whole width. That's an awesome amount of storage, and exclusively for her. Build it bug tight, dust free, and painted. That upstairs storage easily took all the old stuff that any rural household tends to accumulate because it "might be needed someday". Things like Grandma's sewing machine, Aunt Hilda's dishes, and old National Geo mags. Now all that is available, dry, save, and out of the way. Our house is far nicer too.
Walls: I put money into in real good wiring and insulation, but the inside walls stayed covered with only a medium -duty clear plastic for years. Part of it still is. That was good because I could see the studs and wiring while deciding on shelves and stuff.
Floor: I did part concrete floor (just for the machine tools) and left the rest hard-packed dirt. It's been 40 years now and to my surprise I find that the hard dirt is a nicer surface in almost every way. High use areas get astroturf throw rugs.
HEAT: I got smart sometime toward the end of the floor pour. Not smart enough to hire the concrete delivered - I was still mixing by hand - but smart enough the second time to put a roll of that orange heat pipe down before pouring. It's special metal sandwich plastic Pex made for hydronic heating. Not expensive at all if you buy one continuous roll and just let the ends stick up. I put it down directly on the ground right before pouring the concrete. Now the whole shop can be heated with a simple domestic hot water heater. Fantastic. Warm Feet! You can bet I'll never miss that trick again.
Utilities: I ran underground PVC from the house for wiring. Wish I had run some extra pipe while I was at it. In the future, any ditch I build will get a few extra runs of 2" heavy PVC laid with a nylon cord inside all for future projects. Same for any PVC pipe under anything especially a concrete floor. Put in extras pipe; why not? Same for any ditch, might as well lay some extra pipe in there too.
Roof: Not much beats a metal roof screwed down. And if you can stand the galvanized look, the best metal is the heavy gauge "strongbarn". It's strong enough to go over stringers directly, though figure that eventually you will want to insulate any metal roof so plan for that happening. Don't stand on the rafters to put it on. Use ladders or scaffolds from inside and put on a piece at a time. Nicer job and safe.
The Far End: After a few years I chose a wind-protected end and put in a couple of posts to make a simple open-walled outside tractor shed. In fact, that roofed over open area with one wall turns out to be a great place for outside projects of all kinds. I lucked out by having the right place available, but doing it again I'd design for somday having that open shed option attached on the end even if it means less inside space. It could always be enclosed, I think it you'll find it better as a sort of attached carport. Very nice work area in the summer.
I hope this all helps someone. They're all things I've thought about after using our pole barn for 40 years.
