Dead Roof

The living roof had some leaks, probably due to the jigsaw puzzle work I did with scrap plywood. I fixed a pond liner over the plywood but there were a few low spots and water was sitting in gaps where plywood pieces weren't flush. Somehow water was finding its way through and there were a couple wet spots on the wood supports whenever it rained. I decided to strip off all the dirt, straw, and gravel and put up a new roof; I left the pond liner just to have a waterproof barrier underneath b/c the shingles aren't the best and I'm sure they're going to leak a little. After I cleared the living roof, I cut tenons into two poles and lay a beam w/ mortises on the ends across it. I built a basic 2x4 frame off of the beam and covered it with shingles. Here are some pictures of the finished roof and surrounding area.

Feed Storage Roof

I put a small extension on the cob wall to make an area to store the goat feed. I'm planning to build a couple of shoots into the wall with bowls on the end. That way I can just dump their grain into the shoots each morning without wrestling the goats while they try to get at the bucket of grain. The extension is curved so I anchored one post to a concrete block on the ground, the other into the cob wall. The posts are white oak. The beam and rafters are a mix of white oak, cherry, and cedar. The cedar tree came down on its own. The cherry died so I cut it down. The white oak was perfectly healthy but I cut it down to make posts for the greenhouse. I used the leftovers to frame the roof over the feed area. I ran some old 1x2s between the rafters to hold the shingles. The shingles I put on were ones that we bought to repair the barn roof but weren't able to use. Progress is slow but steady...

Goat Pavilion

I started this project because I wanted to give the goats a little more room, put down some concrete to help keep their hooves worn down, and put up a shelter to keep their food dry. The first thing I did was dig out a small foundation and pour a concrete slab. Mixing bags by hand and pouring them one at a time isn't the fastest method. I included a drain, which is just a piece of plywood over a large buried flower pot and a drain plate cemented over a hole in the plywood.

Since finishing the foundation, the whole thing has become an excuse for me to try and learn new building methods. I turned the roof into a living roof. I used 4x4 treated posts, 2x8's for the walls and a 2x4 frame. I put double 2x4's down the center and supported them on a cedar pole. The roof is lined w/ leftover plywood, which is kind of jigsaw puzzled together and reinforced at some of the gaps with more 2x4's. I lined the plywood with a sheet of pond liner, covered the liner w/ gravel, straw, and soil. There's a pvc pipe drain along the back. I was planning to run the drain into a rain barrel and use it for the goat's water. Not sure if I'll try that or not since I had a LOT of trouble w/ the rain barrel for the chickens. It's a trick making those things water tight when you have to have a spout at the base and can't reach the inside. Anyway, I planted wildflower seeds on the roof but they haven't sprouted at all so it's a soil roof right now.

I decided to surround two sides of the cemented base with a cob wall and then run the wall up to the chicken coop. Unfortunately, I didn't read enough about setting up drainage for cob before I started building the wall. Part of the wall is sitting right on the concrete slab, which might be an issue. But I did dig out the other side of the wall, put in a rubble trench and lined it with brick. Still, I have about 2 feet of wall built now and the base is not drying. I will probably put a drain in front of it.

Since the wall runs along the south end of the chicken run, I wanted to put some openings to let light through. I made a few wattle frames with sticks and chicken wire to frame "chicken windows". I have them all cobbed in now and they are surprisingly solid.

The cobbing is taking a long time. I can put up one or two batches each day after work and about three each day on the weekend (any more and the wall isn't solid enough to work on). Two batches equates to roughly one inch of height on the entire wall. I can mix and put up a batch in about an hour. I haven't kept track of how long I've spent so far but at that pace, to make the wall four feet, which it needs to be to keep the goats contained, will take 96 hours. Then I have to put a roof on it and finish it. And this was just supposed to be practice so I didn't screw up the greenhouse!
