Description

March 15 move-in planned

A

So we have the walls here coming up. The technique is basic wall technique got a block on the bottom moisture barrier, then the bricks and a double wall here, we're filling it with straw and some borax for rodents. We've got the vapor barrier on the inside wall. The outside wall has no vapor battery. It's going to get stuccoed, we've got the double window box, that's two feet across and we're gonna frame the window in there.

A

What else? What other details? So how.

B

A

Do tell us the detail on the straw, so we built the walls up to like three feet.

B

Yeah, there's a actually a little taller than three foot and then we put the vapor barrier on the inside and so that'll keep the moisture out of the wall. I mean we won't get all of it, but we'll reduce it to probably 95 percent. Look.

A

At that it's vaporizing.

B

So you can see it's holding the moisture from coming in here. The moisture there see so.

A

B

It there and when the moisture levels goes down inside the house, then the these blocks will release it back into the house anyway. But what little bit of moisture does get in here? These blocks should be able to handle that moisture and it'll mitigate it on out.

A

B

We have to have a breathable surface, with lime, plaster, earthen lime plaster, so that'll. Let the moisture breathe out what a little bit that's in there.

A

And then for the single wall tell us about the little buttresses here.

B

uh Well, we need something for a single wall, kind of give it a little more bracing. So these buttresses what we're gonna do once we get them all. This'll all be stuccoed and then we'll come back and we'll have built-in shelving that'll be at least 12 inches, and the shelving would be built right around the the little buttresses here.

B

So the two things that the shelving would be all one piece and that'll help kind of stiffen the wall up and then, of course, the buttresses do too and that'll give you usable space and then, of course, the the wiring will be uh installed underneath the bottom of these shelves. So you can't see them for electrical.

A

Yeah, is it easy to keep the wall straight here? Do you use a string or yeah.

B

How do you do it? Do you just eye it or oh? Well, some of these were done by you, yeah there's a little bit of undulation in them, but.

A

B

Wall he's got a string on he's stringing them across here.

A

String them across the length.

B

B

He strung this one, these two and now he's trying to string this one, but some of the bottom ones weren't see how they're sticking out a little bit yeah and then it's.

A

Out together, pretty decent, it's.

B

In there, but I'm gonna get the stucco. You fill it here and you fill it here and you don't really see that stuff. You know, but it's uh yeah real, close yeah, so we're trying to get up and then my plan here uh marching was we're. Gonna bring this wall right on up clear up until it hits the ceiling or so close to it and we'll cut around as tight as we can.

B

When we lay the blocks tight, then we'll stuck all this in tight, clear up to the clear up as far as we go, this will all be suckled in that'll. Keep the rodents out on this side and then we'll use some reinforcement, along with the stucco.

A

What about the so there's the tyvek type r, underneath that the bricks go all the way up to that yeah go.

B

All the way up to it, okay, but.

A

B

To keep anything out when and then the.

A

B

It's just like your details from those architects on those other ones the inside. If you look at the wall detail, it comes down. It's all one piece: the insulation comes up this way and up through that void, and this wall just comes up just barely above the ceiling.

B

Now that architect he takes, and when his wall stops, he sprays a vegetable-based foam in there and that seals it all up in like like boring, bumblebees and and.

A

He said they won't, who is this architect.

B

um This guy I've done some work for him. He's been doing some uh planning for some other projects like that. One.

A

Is he a cb architect or just.

B

Just an architect he's uh he's bro. He built this he's one that sought me out because he want he likes building with these things,.

A

B

He that's, this is what they use overseas and and.

A

Yeah, so when, um let's see so when can we expect to finish the walls to close in the structure for livability.

B

um That's another question: I think this part here. What we're going to do is we're going to do the whole north side, clear to the corner and those four rooms down and we'll just we'll just get them that to that point, and then these four rooms, we'll have six rooms with six rooms, be enough for the middle of the month. Yeah so see we could get this part done from that wall that we got to come up on. You know.

A

While it existed already yep.

B

So we'll get this part done this.

A

Is all enclosed.

B

You have the glazing in all. This can be done.

A

B

Then the outside, I probably won't stuck it. We need to let some moisture out the inside we'll go ahead and get some stucco on it by.

A

The middle of the month, which month february or march, not.

B

February, it's already almost it'll, be a tight goal. Yeah.

A

So mid-march we're going to try.

B

To start moving.

A

In yeah we'll see.

B

We've got to get some power in here and I don't know what you're going to use for power.

A

Power utilities, water cistern, well lots.

B

Of things, storage over there for water and in that boiler room that utility room uh-huh.

A

B

Gonna you're gonna catch water off your roof.

A

Yeah, but that could be no. We can do that actually outside we'll get into the details on that yeah yeah yeah.

B

So we can put up, we can put a few tanks in here and store it and throw it in right off the roof and filter it inside and it'll stay warm. This is this going to be your office.

A

This is going to be the headquarters office right here, something.

B

Like that, yeah they're, both pretty good size.

A

Yeah, this might be. I might declare this my room in a library and lots of shelving in here yeah.

B

Things like that, you can see those spaces, you do have an egress window.
