Thank you for sharing us all your work....

[@BiuroHandloweDACER]

Thank you for your wonderful and very interesting videos. Greetings from Poland.

Regarding the gap, how doesn't that allow heat escape in the winter? Seems like it reduces the value of the great R28 wool insulation. Granted heat rises, but still seems like it would escape through the gap.

[@thiscobhouse]

The warm air inside the building has to go through the entire insulation batt before reaching that air gap.

i forgot to send this email. I know you'll get more eyes on this here anyway. How thick should an all-cob wall be at base and at top for a 3 story home with 9' rooms (32' tall including floors)? Should you use masonry instead of cob if you have no choice but to build into the side of a mountain? Imagine the home looks like 1 story from the height of the slope and 3 from the base. Is building on a slope even feasible with cob if the land and (concrete) foundation are even done correctly? 20+ tons of rock seems a little sketch, but I would absolutely capitalize on this if it is possible. Thank you for everything you've done for the community. I am now a happy participant and homeowner thanks to you.

Some serious engineering would be needed to determine the tapering of cob walls for a 3 story cob building. That's something I can't accurately answer. But they will definitely need to taper, unless you can build them perfectly plumb/vertical all the way up. Any of the structure that is covered or underground, I would recommend concrete walls. I have a video here on KZbin regarding bermed cob homes. That one might help you out. Sure, you can build on a slope, but the foundation will need to be robust. It will take a lot of foundation work in the case of a steep slope. You're welcome! Hope these quick answers help some.

@thiscobhouse more helpful than google has been in 3 months. Thanks again 😁

[@kjell744]

If you are building on a slope it might be a better with a basement or a plinth than a normal foundation.

[@aaronvanhoucke2065]

would replacing the bugscreen and wire mesh with a nicer looking wood planking still work if you ad metal ventilation ports? or won't there be enaf airflow. I live in belgium and i have niver seen it done this way here.

[@thiscobhouse]

I think you would still get enough airflow that way. Most soffits these days only have tiny air holes. I don't think that's enough room for airflow, but you don't need to go as extreme as I do with the soffit venting in most cases.

Is there any video on how this home is made? The straw bale structure is nice

[@mouthfulacoque3580]

I would buy his course. I got it while it was $50 and I would pay the whole $500 now knowing what's inside. It covers the entire year of construction and has information on every single thing you couldn't think to ask about "monolithic adobe" construction without knowing architecture first hand

[@thiscobhouse]

Yes, I've documented the building process so far. Perhaps begin with this one: kzbin.info/www/bejne/qaeZnImVm95lbdU

@@thiscobhouse Thanks

[@Warrenneiva]

Iwould like to travel to the US to learn these techniques, I am a bamboo craftsman, would anyone be interested in my work in the US?

[@angusjohnson3210]

How much did it cost to insulate the roof?

[@sebastianjanicki3366]

Hey, I live in Poland where there is really cold in winter. Im just thinking if those air vents will not allow to get too much cold into the room. What do you think?

[@ilovegoats3851]

I'm not sure about those vents, but if you're considered about the air being to cold. Put a 4" pipe in the ground under the frost line in your area. I'm not sure how long it needs to be to work. Attach it to your with a fan and a vent filter to you house. And on the other end put chicken wire and a screen to keep critters out. Underground is always 55° ish. So cool in the summer and warm in the winter. I think that's called geothermal, I don't quite remember.

[@mouthfulacoque3580]

for as cool as concrete is, I had a *totally unique and innovative* video idea /sarcasm fr tho, would cob be an adaquete filler in place of modified concrete for use in stone masonry? I have lost my shit trying to find an answer on google and I want to assume that doing this in a ventilated area free of high ambient moisture would be appropriate. I would also hate to assume with $18,000 worth of stone.

>airflow above the insulation Are you at all worried about insects building hives / nests up there?
