Making progress
Started working on making cob slip forms and put in door frames. We got sand delivered and brick work should start Monday 😁

Exciting! This is all looking so good. The forms look great too. Are those hog panels? Curious where you found them.

@Jessica Poe Oh, nice! I've been seeing those display shelves a lot lately, and wondering where someone could buy some. Nice find!

Building a COB house in 2 phases.
Hello to everyone, my husband, our daughter, and I have a nice piece of land where we are starting our project to self-build a COB house. We'd like to ask you all about your experience connecting a new section of a COB house to an existing one. We want an 8-meter x 14-meter house, but we can't build it all in one go, so we have designed the floor plan with two rectangles, one attached to the other. Our doubt arises when connecting the walls of the first construction to the new one ..... any ideas? Thank you all for this great community 😉

If you can integrate the foundations of Phase 1 and Pahse 2, connecting the walls should be no issue. There are different ways to integrate a new cob wall to an existing one. You will basically have rebar or wood anchors sticking out of Phase 1 wall, and then build the new cob wall around those anchors, integrating the two walls. Then you plaster over the seam of where the walls meet together.

Making door frame openings
Okay walk me through making the frame openings. I'm looking at the pictures you have, and it looks like the boards span the entire 18 in width, do I really need to use 18 in boards or If I use 10 in boards would that cause issues?

Hey Jessica, So, the window/door frame boards don't need to span the width of the wall. They can, but it's usually not necessary (Unless your putting a door and a screen door both on the same opening. For windows this is probably never needed.) The window frame only needs to be placed in the wall wherever you want the window to go. It can be towards the outside/inside/or middle. The lintel above the window/door will hold the full weight of the wall that's above the opening. Let me know if you need anymore clarification.

I've never heard of this used as the fiber, but it might work! It will really depend on the tensile strength of the cattails, and its shape. Do you have some dried cattail?

@N P It is a great video he made. I actually saved this one a few years back and used it this past Fall as instruction when I built my greenhouse.

@Mi Hi Yes, my kitchen will be a separate building in this case. I'll also be having an outdoor wood-fired bread oven, and an outdoor grill area.
