My plan was to have this first piece (a 10" to 8" reducer) connected directly to the manifold and an 8" T, for a cleanout, connected directly to that. Are you saying there should be a bit of a length of 10" before I reduce down?
Here's attempt #1 (it failed). I decided to go with bubble wrap for formwork. It's possibly the best texture of all time and if one of these ever needs to be shipped, the formwork could be part of the packing. Problem is, it's too stretchy at this scale and blew out.
This thing's going in my basement, despite Ernie's specific advice at the pebble style workshop. It's my best option right now. Since it's gonna be surrounded by lots of concrete (floors and walls), I had this idea that maybe the core part could be in a concretesque shell. As the core will mostly consist of a bunch of molded refractory it won't be too durable. A hard shell could help out in this regard and I can form in some voids to be used as hand holds. I've had this affinity for fooling around with fabric formed concrete for a while, so it's an excuse to do some of that. One of those "you know what'd be cool?" moments for me. Here's an example of a piece of furniture made with fabric formed concrete:
Kevin, I attached the model I've been working with above. It'd be great to have lots of people fiddling with it. The files could even be shared to google's 3d warehouse where we might infect more brains.
I'm sitting here thinking that it makes sense to do what Mike describes in his book. That is, decide where your downhill retaining walls are going on the given site and backfill against them as you excavate uphill. I'm a little confused why there will need to be fill brought in. Is it because there's very little slope and 0.7 is sitting a little more "proudly"?
It IS possible to bring a rough topo in from google earth, but in my experience it's not that accurate on a micro scale such as a 400 sq.ft. structure, and it makes the model a bit more complicated thus slowing things down.
Tim S., I'll work on the changes. I have a concern with having the 4 purlins you mentioned sharing the same post. My concern is that the joint could get too complicated and thus become complicated to construct. It looks to me like the uphill/downhill purlins all go onto the posts first, then the beams are set in place. In this scenario, the joint where the shed meets the gable will have purlins coming together at 2 different angles, an then a beam will be secured over top of them. I don't have much framing experience, but wouldn't that mean 2 fasteners into the supporting post, and how then would the beam above be safely fastened to this compound joint? Maybe there is a simple way of fastening this all together, but it's outside of my knowledge set, thus my attempts to do something different.
Paul, I'm happy to keep working on this as I can. It's fun and I want to wrap my mind around it. Unfortunately, the going will be a little slow for me right now. Two things I could use clarification on... what do you mean by:
I would also like the retaining logs to be far back from the roof wood.
Are you talking about the retaining logs on the "winglike" bits, or the uphill patio?
I am thinking that the slope to the ground would be shorter, the retaining wall would be smaller, and the wood in the retaining wall would be less/smaller - thus easier.
Does this mean that the overall structure is sitting more above ground thus meaning less of a need to retain earth?
It seems there are a few items Paul really wants to include in this first pooper attempt. After spending a fair bit of time kicking it around with him, I'd say the reasons are many and based on years and years of experience, research, and legal stuff among other things.
1) Absolutely no poop touches anything but the inside of a trash can and other poop for a solid 2 years.
2) The pooper can be dragged around.
3) Pee diversion.
4) Smelly stuff is siphoned out as quickly and efficiently as possible in all seasons and during the day and night.
5) Big broad roof so no paint has to be used.
7) For more of the inside scoop on poop, there's probably no substitute for showing up in person and enjoying some face time with the Duke himself. Turns out talking poopers can be enjoyable.
This was tough. Here are the 12 that seem to have affected me the most, so they get my vote:
007 - Masanobu Fukuoka Larry Korn
053 - Toby Hemenway native plants
056 - Horticulture of the United States of Pocahontas
087 - Replacing Irrigation with Permaculture
110 - Consensus and Assholes
134 - Joel Salatin Part 1 (&2)
169 - Sepp Holzer Interview
175 - Tree Bogs and Natural Burials
181 - Mason Bees Part 2
202 - Paul visits Joseph & Jacqueline Freeman of Friendly Haven Rise Farm - Pt. 1 (&2)
223 - Poop Beast Part 1 (&2)
236 - Interview with Sally Fallon on Raw Milk
Also, I think peeps would be well served to watch the videos on dandelions, comfrey, and hugelkultur too. They're short and full of good stuff.
The book sounds great, kind of like The Barefoot Architect meets Mollison's big black book. Are there any books or resources you could point out as resources for learning about all wood joinery? I know Ben Law is widely known in permie circles, maybe some others? I think I saw a detail where you scribed a round wood post onto a rock. How did you acquire this type of skill?
Ben, I'm impressed by your website. While digging through some of the images on it, I saw what looked like drawings of a possible Oehler structure / hobbit house / wofati? Can you tell us more about this? Is this a project in the works or completed (I see some actual pics in the gallery that look similar)? What can you tell us about the building materials choices as they pertain to location and climate? Also, I'd be interested to know who did the drawings. I thought they were excellent.
Doing just a little more digging with the above video as a starting point. It looks like Michael Garnier has done a fair bit of work in the getting things permitted space. One might start looking on his site at construction and engineering plans and stand on the shoulders of the work he's already done...
Also the Earthship bunch has done a lot of work on their "Pockets of Freedom" map to identify counties where building permits are not a hinderance. If you can build an earthship, a treehouse shouldn't be a problem either.
