It really does seem like a lot of Cob Donald. We would not have been able to do so much if not for the mortar mixer. Vs the foot method it's like having a whole volunteer group working for you everyday. Check out this YouTube video of the mixer and the pond. I added some recent pics of the pond and some of the deeper clay deposits we are collecting from it.

You sure have created a beautiful project.
My internet is a bit slow, so I only have seen a small fraction of pictures and videos.
I think you have more artsy skill in your pinky, than I have in my whole body.
Especially liked the king bed with kid area at foot of bed, I really hated our previous home as the baby's room was three rooms away. Now that he's almost a teenager, I can appreciate separation.
Definitely will check out your YouTube channel.

Congratulations,
Mike




Thank you. I will say that I probably have plenty of art skill, but so do most people I think. The reason my home is so artistic is because I was not limited by the design of commercial materials. We love the open kitchen design. It really works for a 600-700 sqft home. The transition aids in allowing multiple different spaces to share same transition zone so that there us a synergistic effect on overall space. I have plans to expand from the 1100 sqft we have now to 1500 sqft with that addition of a master bedroom and when our kids are teens I'd like to have them build their own rooms.

Hey Mike thank you so much for your kind words and enthusiasm. Same to everyone else who has questions. Please allow a little time for reply. I thought I would answer your questions Mike with a video. It will probably show up on the YouTube channel as well. There isn't a lot about this yet, but I was thinking about buying an indoor/outdoor weather stations and post the data logs. Here's a video about how loud it is in rainstorm. I included a pic a few minutes later.

Here is ypur answer;

It has now been 3 years and we are mostly finished and living in the structure. I am currently building out the Laundry room and will soon post on this forum a couple dozen pics and 4 or 5 videos of the progress since last post here. Thank you for replying and getting me to remember. Here are a few recent pics

This is a homemade window in my cob house that Simon Gonzalez made a sculpture around. We made homemade shellac pigment paint for it. The inside is actually made from an old rusted out fire pit.

Hey premises. We have been making great progress here at the Cob Barndominium. What could be the final layer of our floor has been put down. I say possibly because the final layer cracked quite a bit because there was too much clay in it. I am going to try and to add material to where the micro cracks are. We have found a very light colored clay on our property and we used it to plaster the inside of the pantry and the outside of the bathroom wall. We will probably find a few places to use it cosmetically as well. A tadelackt like lime plaster was applied to the bathroom and was burnished with a smooth piece of porcelain and African black soap until smooth. I am planning of finishing out the whole bathroom with a green mica and pigment coloring applied by burnishing and Venetian style wax polish made from beeswax harvested on my property. I am just now getting access to start finishing out all of our kitchen cabinets and our 18 kw quarts infra red tankless whole house water heater from Siogreen just arrived. I’ll post more videos and pics soon. Thanks a lot guys for keeping up with the build.

Hey guys! We have another photo and video dump. Officially we have finished the walls and are working hard on the floors. We have started making homemade shellac paints and are using a 1:1 ratio of store bought shellac and Denatured alcohol in a spray bottle to stop knockdown on the walls. More photos soon. Thanks for keeping up with the project.

   Hey guys! I have recently been doing a lot of testing with boiled linseed oil, lime, shellac, and natural pigments to find the perfect way to finish the walls of my cob house. My requirements were there be nearly no dust off if the wall was touched or bumped. I have kids, so I figured it would be to messy. I wanted the ability to paint or color the mix highly. The house needed to breath through at least some of the coating somewhere in the wall. I also wanted a hardened surface that could with stand some rain and even slight spraying from a hose. Also it needed to be non-toxic.

  The just of my problem was box store boiled linseed oil is very toxic due to the nasty chemicals added. The natural stuff is pricey. It also leaves a heavy oil smell behind for some time, and didnt recieve pigment well. I also really didnt like the dust off factor of strait lime and the need to buy refined sand to properly tint the plaster. Also, lime has a very bad manufacturing process.


   The outcome is shellac. After the solvent, usually denatured alcohol, off gases the coating is basically food safe. You can make your own strait from flakes, and it mixes to the consistency of house paint with pigments very easy. I wanted to be vary carefull not to completly seal off walls, so I cut down the shellac very thin with Denatured alcohol to the point where I can spray it strait out of a spray bottle and it stops almost all knockdown. The surface is also substantially hardened to the point of grinding off a part of my nail while I was trying to scrub cob off. It still has enough pores to be breathable. If shellac is painted directly on the wall it becomes waterproof and damage proof. The cob feels much more like concrete. The painted surface will probably stand up to light pressure washing. It dries incredibly fast and UV resistant. Ill show some pics of my testing.

    As far as pressure washing goes, I also intend to test the ability to paint Shellac directly on wall in shapes and designs and then pressure wash off cob that is not been treated to make a textured surface of the design. This is what the tribal design is inteded for in the second photo.
