Cob Quonset House - photos
Here are some photos from the "Cob Quonset House" that we completed a few years back. The home builder had put up a metal quonset hut structure, and they wanted the two end walls filled in with cob. Here's what it looks like!

@Jj Vee Coloring concrete is easy enough. You add a pigment to it before you mix water into it. The problem is, for large amounts, a concrete truck will not put pigment into their mixer. :)

@N P The metal airplane hanger-looking roof is the quonset hut.
Building Layout Tip! Batter Boards and Stringlines
I've just begun the layout for constructing my new timberframe kitchen. Watch to see how I do the layout. Please leave questions. I'd like to document this construction for you all here in the Skool group.

It's a 120 sq ft overall footprint. It'll be my kitchen space with basic necessities. I've been cooking outside for the past 3+ years since I got my land.

@N P - It'll be it's own standalone building. But very close outdoor walkable distance between everything. - I haven;t completely decided yet. It could be a mix between cob, hempcrete, and straw-clay. - Yes, it'll have sink with running water. I can definitely film that. - Yes, sure! - You can, but the walls will be as thick as the pallets. I prefer the larson trusses (reference the straw-clay lessons in the Classroom). - I have 3 cats. Leo, Lyra, and Luna. :)

@Levi Brooks Very cool. If you don't have property yet, I have some good resources in here on finding the right land.

@N P Kremer Pigments is also one of the best suppliers for non-toxic, natural pigments.

@Shannon Carpenter Coarse sand is better. But we did build this Florida cob with "playground" sand, which was quite fine grade. Ideally, I would use a grittier sand though, like a masonry sand.

Yes, pigment can be added. I usually add it for mine, unless you find different soils with different natural pigments. You can order them online. They come in powder form. Careful with the conventional concrete ones. They're good, but some do contain toxic ingredients so just don't breathe them or leave them on your skin. Yes, the RE pigment and lime plaster/tadelakt pigments are the same products. I don't think I have any videos on the Florida RE columns, but I have this recent video documenting a lot of the process: https://www.youtube.com/watch?v=MCVXLsgGIrI&t=39s
