Compressor plumbing to detached shed

[CoogarXR]

I have a shed that sits immediately behind my garage, about 3' away. I would like to move the compressor into the shed to free up some space and cut down on the noise. But I have a question:

How should I plumb it? I thought of four options:
1. Plumb it straight across, about 3 foot off the ground. PROS: Easy. CONS: Ugly
2. Elbow it down and across the ground (or buried), then back up. PROS: Much neater looking. CONS: Will water get trapped in the low spot underground?
3. Plumb it up high, and enter in the garage loft, and drop down through the ceiling. PROS: Sorta neat looking outside, very neat inside. CONS: More install work than the other options
4. Install a 3" PVC sleeve between the buildings and just use the hose I am already using, lol. PROS: Super easy. CONS: Redneck.

Also, I don't know if it matters, but my garage is heated/cooled, but the shed isn't. So will condensation be an issue? I plan on putting a water trap on the garage end. But unless I go one of the straight-across routes, there is no way to get the lowest spot on the plumbing run to be inside the garage.

What would you do? I just want to get some opinions.

Here's a visual of the layout of the buildings:

Let me start by saying I've never gone from nonheated to a heated building. But I would think you would almost have to keep it high with water traps just to keep it from freezing /cracking in the winter. I definitely wouldn't bury it for the exact same reason. Just my .02

Bury it, crack a valve in the garage on occasion to blow any water out, it likely wont be much. The warm garage wont be a problem, condensate occurs when it goes warm to cold.

Bury it

If you don't plan on doing any digging in that gap later on, then bury it...

A rubber air hose buried in a sleeve wouldn't bother me, you can even get 10 ft ready made 1/2 hyd line from farm store for thrifty price.

Agree^ Bury it. On the inside, plug a Tee onto the pipe with a ball valve so it can be drained. The middle leg of the Tee will point up to reach your lines.

almost a carbon copy of my set up. I would not worry about freezing, I had a 3/8 air hose to my shop all winter & zero problems with freezing.
I have some 1"pex al pex that I'm going to bury . if it ever becomes an issue, I will resolve in in one way or another .
Original plan was to bury a conduit of some type and run a 1/2 air hose thru it. found the pc of pex at Habitat & that became my new plan

I'd bury a 3" plastic / ABS pipe conduit and run an air hose thru it. Gets rid of water issues, corrosion issues, all sorts of future maintenance issues.

I am going to do similar and bury mine. I will have to go about 30 feet from my shed to where I will have my reel inside my garage. I am going to use rapid air for my setup and if I have enough left over, I will probably bury that to plumb it to the garage. Fortunately, we don't get very cold here, so not much to worry about in that regard, but will be nice to have air in both places.
