Mine is very similar to this one, but mine is 24L x 12w x 11h with the “barn style” top, don’t think they make that beast any more https://www.northerntool.com/shop/to…1404_200411404
This topic comes up from time to time, so I’m lazily copying and pasting a prior response : ) :
love my Shelter Logic hay building. I put it up almost 10 years ago specifically for hay and its still going strong. Its survived several hurricanes, including Sandy.
I chose a spot that was protected from the wind (though I have had damage due to falling tree limbs over the years). Before installing, I prepped the ground for moisture, I graded the earth (by hand) and installed 6" deep bed of stone (by hand!) and put a heavy duty tarp over the top for a moisture barrier. Stacking hay on single pallets will result in musty bottom bales, but double pallets work to keep even the bottom bales clean a year later.
I can stack 7 bales high down the middle, 6 on the sides. Though experience has taught me to stay 5 high on the sides, 6 in the middle. I can fit 3 pallets across, 6 pallets deep, the barn will hold about 240 40# bales, though I usually stay around 210 so I have some room for other barn items like yard equipment.
I don’t stack to the ceiling as that creates a moisture trap. I also don’t touch the sides of the tent with hay if I can help it as the plastic will sweat in certain circumstances (heavy humidity, hot sunny days, cold nights).
I did have moisture issues the first year, even with the doors left open. Its routinely hot and humid here for about 4 months. Condensation developed in the apex of the roof which rained back down on my hay. I cut vent holes in the doors as high as I could go without risking ripping the door. I reinforced the vents with gorilla tape. Those two little vents have eliminated my moisture issues.
Putting the barn together was a supremely unpleasant experience, as mentioned, the written instructions stink. Nearly cost me my relationship with my boyfriend : ) Customer service was great though, and directed me to updated directions on line that worked much better. We were clever and laid out the roof portions on the ground first and then marked them with a Sharpie.
We were not clever however and didn’t make sure all the bolts were installed with the nut portion facing inwards. The few that are facing outward have caused rubbing issues on the covering. Were I to do it over again, I would duct tape all of the joints and bolts to eliminate rubbing.
I did not use the pathetic grounding augers that came with the kit. I bought 12 2’ long rebar hooks, drove those into the ground and used ratcheting straps to secure the building to the earth, and used 8 2’ augers, 2 in each corner to anchor. After the covering was in place, I back filled the sides where it overlapped the ground with cinderblocks and earth to keep it from flapping.
It took about 4 years for pin holes to start appearing in the roof from sun and tree damage. I put heavy duty tarps over the top as second and third layers before any real damage occurred. Everything is safe and sound a decade later.
If you have a protected area, and the patience and help to really install it correctly and double down on securing it, its a great, fast, inexpensive option for hay storage.
I will add, the nice thing about the dark green color is that it heats up on even the most cold and overcast day. Doesn’t take much sun at all for it to get 10° warmer inside. Even though we can get snow measured in feet, not inches, snow pileup has never been an issue. The barn style shape is sturdy and snow sheds quickly.
