My daughter and I made this hoop shelter for our pigs 5 years ago and it is still in great shape. It is fairly easy to build with just a little elbow grease.
This shelter is built from common materials and goes together easily.
2- 16′ cattle panels cut down to 12′
2- 4’x8′ sheets of untreated plywood
4- 6″x4″x8′ treated posts
4- 1″x3″ untreated boards
1- 10’x12′ tarp
Misc: Screws, Lag bolts, metal plumbers strapping, and fence staples
We started by notching the ends of the treated posts. The notches enabled us to overlap the ends of the posts to be glued and nailed together while still giving us a flat surface all the way around. We notched the posts with a circular saw, we used multiple passes to create slices half way through the post. The slices were then chiseled out and smoothed. Update to our original build- We would at this point in the build add a sealed floor of some sort. Hindsight is always 20/20.
In order to secure the cattle panels in a curved position, we put lag bolts on 2 alternate sides. The lag bolts were put in 2 inches from the outside edge of the posts. We used 6 bolts per side and spaced the bolts evenly along the post. The bolts were left out about 1.5 inches so that the wire panel had a good point of contact.
We wired the to cattle panels together along their length and put one end up against the bolts. The panel was then carefully pulled down so that the opposite end rested inside of the bolts on the other side. We have at that point a base and a hoop. The ends were secured in place with some large fencing staples, and all of the sharp edges of the panel and wires were removed to prevent injury.
The end panels were the next piece of the build to tackle. We held one plywood panel up to the end of the hoop and traced the outline onto the wood. We cut out the curved end piece and secured it to the wire with plumbing strap and screws. The entrance side will have a doorway cut out as well before it is attached. We cut two 1″x3″ boards that ran from top to bottom inside the end pieces. we attached them with screws to give the end pieces more stability. We double checked again for sharp points of screws and made sure to grind them down to prevent future injury.
We covered our hoop buildings with tarps secured with lathe around the bottom edges. This worked great right up to the point when the sows started their nest building phase. They tore huge sections of the tarp off to add to their nest even though they had plenty of straw. We have since corrected this by adding sheet metal strips to the bottom of each side, and we completely covered a few huts and removed the tarp all together.
There is always improvements to be made, and the first version is just a starting point. These are great huts, but by all means not perfect for everyone. Like I mentioned earlier we would have added a floor to these, and when we build more we will add that option. We have had these huts for 5 years and have only needed to replace the tarps. As are farm grows I will need to start building more.
