The problem with cob is that big corporations cannot patent it, or sell you a product. They have the money. They influence the laws. Cob Is a great material.
Cob house does not rot or mold. Of course it can come to pieces if the rain consumes the structure. But in general it can last 10,000 years and still be reused. The earth/adobe you gather from ground is already several million years old. It is the most ecological building material you can find. Does not burn like wood, does not rot like wood, does not damage nature like concrete. Can be used as supporting structure and for thermal insulation. You can also use clay for making roof and floor with tiles. You don't need to oven floor tiles. Fireplace can be also formed from same material. It is insanely versatile. It can be even waterproofed without ovening it. One thing should be kept in mind when building cob house is to build high foundation so that the bouncing rain doesn't hit the walls and consume them. Another thing is to make overlapping large roof with drainpipes and wells so that the rainwater will be directed away from the building. Otherwise it will seek into the foundation and into the walls and destroy them especially if you have frost.
There are cob houses in Britain and other places of the world that are over 400 years old. As long as you maintain them and have a good roof and boot you're good to go.
Problem is, cob construction in UK does not meet building regulation unless it’s incredibly thick or covered in a man made insulation layer. That is due to change thanks to the research work undertaken by the UK/France CobBauge Project to create a naturally insulative cob material combining a cohesive structural and thermal wall layer.
Our house is 350 years old and made of wattle and daub, clay lump with a timber frame. It's cool in the summer and we have woodburners and a central heating system. We have single glazed sashes and lattice windows. Other houses and hotels we go too always are too hot as everything is hermetically sealed and air conditioners are used. We love our old home in England!
It’s been done on a small scale in the hills outside Coquille, Oregon. They have all that, except the barns, and at least half of a bath house. Around a dozen cottages and hundreds (thousands?) of feet of meandering garden walls.
The Navajo Nation does this still as it is native New Mexico architecture but, it is a dying talent I intend to bring back! Researching this stuff to get knowledge to build my own house in Pecos NM!
Yes.... like the Amish ...everybody get together build everything until everyone has a small home..etc. The problem is...very few states even allow these kind of alternative homes.
@@سهمالهاجري There are some very old examples of cob houses in the UK that have survived in spite of the rain. Those houses often have overhanging roofs that protect the walls.
I've been a contractor in florida for years. This guy doesnt strike me as a county building inspector that happened to roll up on the job and discover a non permitted building, so impressed he went on camera in a dirty tshirt, delivered lines and sold the idea. Cmon man
I want to build a cob home with the German wood stove heating that uses minimal wood. I know its straw bale Cobb but I have absolutely no idea WHERE to begin locating plans. I am so grateful you covered the concrete foundation concern. Foundation is everything except in Japanese stick buildings for building on seismic prone land. I just don't think that our weather is going to cooperate with non or lightly insulated buildings for a minute.
Have you read the Hand sculpted House book? I can’t recommend it enough. Light straw clay could be another good route for you, with cob interior elements for heat retention, and a cob floor perhaps. Better insulation value and much much less manual earthmoving.
Going to go see our Art House but what struck me was the cracks in the concrete within a yr. And if I were to use my Loan to build and have it crack immediately after - vote no confidence. And what is really discouraging is it was Designed and built by Engineers contracted by the City of Everett here. Thank You for your time reviewing.
Are cement window sill and lintels really needed in cob construction? Cob building masters in British Columbia build the whole structure just cob, nothing extra and they say they are super durable. Another thought on those concrete lintels, wouldn't they act as thermal bridges brining in heat directly into the house on super hot days and cold on cold days therefore negating the entire passive energy benefit granted by the cob walls?
I agree. All cob or adobe sounds better. My Grandpa's house in New Mexico is made of adobe...was built in the 1800s.. my aunt still lives there and it's a beautiful three-bedroom home. The walls and window sills are about 16 inches wide. We used to sit there when we were 2, 3, 4 years old.
did i get this right? >> no windows or doors for YEARS? so..... nothing forcing moisture to remain INSIDE ..... because the "inside" is still OUTSIDE. this is a nice cool expensive OPEN structure. i feel suckered into watching this video.
Actually, the total build will only be about $15k overall in the end. But yes, I see your point. Windows and doors will be going in soon. I'll update on the moisture in a year or so.
Hey, were wanting to build our first family cob home in the future bur knowing we live in a stricter state we will have to see if our plan is in regulations.... how do we start this process who do we go to?
I'm surprised he didn't mention the performance in high wind and hurricanes; I'm sure they do well, being so massive and sturdy? Good foundation, good roof means it can withstand high wind?
Would latex paint keep cob from permeating moisture the way it should or would it seal it even better? What about a Stucco finish? I think if someone trimmed a cob house out with mouldings and trim and gave it a good white paint job the public would go for it.
Generally what I've learned from talking to people in the industry and going to workshops is that modern building materials aren't compatible with earthbuilding materials because it compromises the function and integrity of both. In the case of finishes, the wall needs to be able to breathe, and latex paint is not vapour permeable. Lime/earthen plasters work really well and you can mix in mineral pigments to create colour. For comprehensive info, I highly recommend The Natural Plaster Book by Cedar Rose Guelberth & Dan Chiras if anyone's interested. They also discuss natural vs standard paints.
Part of the reason people love cob homes is to get away from all the toxins in most conventional building materials...causing respiratory, alergy, migrains and other health problems. So for instance, you dont want a formica countertop in a cob/ adobe home. Natural materials...wood.. .slate..granite...etc . Also did you know cob homes always smell earthy and fresh? No " housatosis". Super cool and comphy in summer and in winter the cob/ adobe absorbs the heat from a woodstove so house holds heat better.
I'm no expert but from what I've discovered about earth building, you have a larger overhang in your roof so that theres less contact between the water and the cob. You can also add extra protection with a lime or earth plaster and having a foundation made of stone or concrete (something like that) keeps the water away from the cob. It looks like they have the overhanging roof in the video and might add the plaster on when its finished? Hope that answers your question :)
A couple coats of plaster. For exposed walls, lime is recommended, but it is hard to find good quality lime. You can add pigments to color it if you don’t want white. As a general rule, anything that repels water (like oil) is a bad idea. A lot of old earthen buildings have collapsed because a nonbreathable surface or coating was added to the outside surface.
A good foundation that directs water away from the building (french drains were mentioned in this is one example of getting water AWAY from house). All well sealed windows and doors, a solid roof, hopefully good overhang to prevent water landing close to the house are MOST important for ANY kind of house to avoid cracks and damage. Easy to overlook the mundane details of boring foundations and lintels and roofs in the excitement of cob ideas -- I know, I've been doing it. I've also lived in a 125 yr old Sears & Roebuck cottage, had some cracks in the lath and plaster walls. Our inspector immediately traced where water had gotten into the rock foundation and helped us develop an plan to fix and reroute water to a flowerbed!
Where did you get your cob material? Are you up north FL where there's more clay? I'm in central florida. Did you get the materials delivered to mix up and build with? Or dig straight from your property? Thanks. Very interested
Alex, where in Florida is this house located? I am looking at lands in FL but how would I know if I would be able to build my own cob structure? Are there specific questions to ask before buying a land for this particular purpose?

@@thiscobhouse I see. So it would probably be easier if I were actually already living in Florida (I am in Maryland).

But how does it resist rain thro 10000 years? its made of mudd!!
As long as water isn’t directly hitting the surface constantly it should be fine. Cob has an ability to “breathe” to a certain extent.
