Welcome To The Classroom

Every day, I receive emails from people who want to build their own cob house, but they just don’t quite know how to get there. They’re always looking for cob workshops and training opportunities.

There are a lot of cob workshops out there for people, but here is where we all seem to run into the problems.

The dilemma is this…

A lot of people are becoming very interested in learning about cob and how they can build things out of cob for themselves. However, a lot of the time we can’t take a cob workshop because its either too expensive, too far away, or we can’t take time off to go attend.

This leaves a lot of good people out on an experience that could change their lives forever! Lets face it, knowing how to build with cob is very empowering! And who doesn’t want to be empowered!?

To get a good understanding of cob building its best to take a comprehensive workshop. The problem here for most people is that these workshops usually cost over $1000! Sometimes they even cost multiple thousands of dollars when you add all of the travel expenses required to just get there!

Traveling to a workshop costs money and time

Most people are just simply not able to get enough time off from their jobs and duties to go take a cob workshop that can last one, two, three, or more weeks long!

I Totally Understand.

I've been there before.

I've missed out on workshop opportunities because of these same things. I know how it feels.

Here's My Solution to These Problems

I recognized these problems in the natural building community some years ago and I’ve finally come up with an amazing solution that you’re going to love!

I’m offering to you right here, exclusively, a completely comprehensive online cob workshop course through videos and eLearning materials.

I guarantee that this course will over-deliver on what you would learn at a regular cob workshop! One or two weeks at a traditional workshop is still just not enough time to cover all the essential topics you need to build your own cob home.

For example, the vast majority of cob workshops, for time’s sake, don’t even cover how to build a foundation! This is absolutely essential knowledge to have, and we will be covering this topic in depth from the beginning of the online course.

But Will I Still Learn By Taking an Online Course?

If you can get a college degree by taking classes online from the comfort and convenience of your own home, then there is absolutely no reason that we can’t offer the same online distance-learning format for cob workshops and natural building courses.

Here are some mind-blowing statistics for you to think about in regards to online learning programs:

  • In 2011, 77% of American Corporations were using online learning.
  • In 2014, 18,650,000 college students were taking at least one of their classes online. By 2019, half of ALL classes will be done online.
  • Online classes are proven to increase knowledge retention by 25% to 60%.
  • Online classes are generally shorter than classroom training on the same subject by up to 25-60%. That saves students A LOT of valuable time!

Benefits of Joining the Workshop Classroom:

  • Save hundreds of dollars compared to traditional cob workshops (this course is only a fraction of the cost)
  • Save days of time
  • No travel required
  • No need to use your precious vacation days to attend a workshop
  • No need to cut time out of your busy schedule
  • All you need is a computer with internet access!
  • Earn a cob building certificate from This Cob House!

Step-By-Step Instruction

This online course will guide you step-by-step through how to build a cob house.

Each month you will receive a new set of lessons and materials. This course is comprehensive in its scope and is spread out over a 12 month period (or you can purchase the whole course at once upfront). The course is extended in time to give you the opportunity to apply what you learn each month.

When you finish this course, you will have the knowledge and confidence to build your own cob house.

Student Endorsements

The online tutorials give excellent detail about cob building. The videos and descriptions are well-organized and easy to follow. My husband and I love this course! I recommend it to anyone who is considering building with cob.

Elisabeth and Brion Vallin

I really enjoy the cob classroom, lessons, articles, videos, and “hands on” projects inspired. I love the pictures and videos, and the constant learning connection.

I appreciate the classroom focus on the historical past and promising direction of the future, showing beautiful pictures of older buildings and cities, those recently completed, and those in progress.

The videos always inspire many ideas and motivate me towards an action plan on my projects. These “How To” videos are amazing, and I’m always open to quick tidbits on brainstorming possibilities.

I have recently completed Roscoe’s  dog house, made of cob, for my folks in GA. Through the classes, I felt educated and confident in every step of the building process. It was nice to review the information as needed. I also hope to be finishing off another project very soon. Thank you all for the support.

A big “Thank You” to Alex for his dedication to his students and to the classroom.

During our 5-day cob workshop in August of 2014 I got the amazing opportunity to work side by side with Alex. All of my questions, concerns, and ideas were answered during our, what seemed too short, 5 days together. If you are planning on building a cob home or other project, but feel like you have too many questions about building or don’t have the confidence in your skills then I highly recommend taking a workshop like Alex hosts before you do! I guarantee you will walk away with the confidence and know-how to be able to build anything your heart desires!! Thanks again for the opportunity!

Devorah Firestone, Maryland

Alex’s class was straightforward, informative and useful. His engineering mind is tempered with clear, elegant thoughts. His easygoing personality makes him great to learn from and work with. I’d love to take another class with him. Many thanks!

Maria Wilbur, Virginia

Alex’s cob workshop was my first experience working with cob and it was very rewarding! He is very knowledgeable and offered alternative solutions during any “cobtastrophes”. I am confident and well prepared to begin working on my cob home sooner rather than later. Alex’s workshop was much more than I expected and worth every penny!

Suzanne Gossett

Alex is an awesome wealth of inspiration! I just can't say enough positive things. You have inspired me and my children, and blessed us with all you are and do. The feeling that one gets when working with cob, that peacefulness, fellowship, and all those good things and feelings are what is passed on from you and the information you give!

What Should I Expect?

Below is a one minute excerpt from one of the introductory lessons and the accompanying downloadable sample lesson notes.


The best thing about the Workshop Classroom course is that its much more affordable than taking a traditional workshop! You will only be paying a FRACTION of what it would cost to go attend a comprehensive cob workshop.

This price is so low, it’s a definite bargain! You can purchase the course in one upfront fee or pay for the course in 12 monthly payments. Each month you will pay a low $17 membership fee to access the Workshop Classroom and all of its features. Or pay $204 upfront for full immediate access to everything.

Think about this…

Twelve payments of $17 is $204. For just $204 you are getting a full, comprehensive cob workshop course. You will never find a price this low for a traditional workshop. Remember, most of these courses will cost you thousands of dollars, weeks of your time, and long travel. But here you can pay a small fraction of those regular costs and get even more!

This course is priced so low, its really a no brainer!

    A.You will learn how to build a cob house from the ground up. All major steps in the building process will be taught so that you will have the skills to construct your own cob buildings. We will begin by learning design principles, site selection, and how to build a strong foundation. Then we will progress into how to make cob and construct cob walls. Later on, we will cover topics such as roofing, natural finishes, and others.

  • Q.How will this course teach me to build a cob house?

    A.You will be guided step-by-step in a linear progression on how to construct buildings out of cob. You will be handed the knowledge and advice to carry out construction of your own cob house. You will receive teaching through video lessons, informational articles, and other supplementary materials online.

  • Q.I’ve already taken a traditional cob workshop. Will I still benefit from this course?

    A.Yes, I guarantee it! Most cob workshops don’t cover nearly this much material. You can’t learn everything there is to know about cob or natural building in a few days or weeks at a workshop. If anything, let this course be a supplement to your regular workshop experiences. You are certain to pick up even more valuable information and skills here.

  • Q.How can this course benefit a do-it-yourself builder like me?

    A.This course will break things down into easy-to-understand concepts and assist you in the application of all the necessary components to building a cob home. The material is presented in a practical format without confusing technical or architectural terminology. This program also offers the do-it-yourself builder the benefits of affordability without the need for expensive workshop trainings.

  • Q.I don’t have any building skills. Will I still benefit from this course?

    A.Absolutely! This course is designed for everybody to be able to learn from. Whether you are a professional builder or if you have no experience building at all, you will be led step-by-step through the processes.

  • Q.How long will it take to apply the teachings and see results?

    A.The course spans a time of 12 months, but you will begin to apply the teachings in the first month’s lessons. Building a cob house is a process and takes time, no matter what. You will be in a constant process of learning and application during the course without getting ahead of yourself and making mistakes.

  • Q.How is this course delivered?

    A.The course is delivered through the Workshop Classroom membership portal. You will be given a username and password to access the Workshop Classroom. There you will find all of the learning materials and tools for the course.

    A.My name is Alex Sumerall and I’m the author of this course. I have taught thousands of people through workshops, lectures, my books, and through my website on how to build with cob, and I have helped to empower them with the information they need make their cob building dreams come to fruition.

  • Q.Why should I buy this course today instead of waiting?

    A.This course is a learning progression. You won’t be able to cram all the information in one short amount of time. If you are interested in building a cob home any time in the near future then I recommend purchasing the course today and getting started. If you are perhaps planning to start building with cob in a few months to a year from now, this would be an ideal time to buy the course and start learning.

  • Q.Will there be tests and requirements to pass the course?

    A.No, there are no tests, grades, or requirements that go along with this course. You will not ‘pass’ or ‘fail’ this course. It is simply a self-study program for you to learn and benefit from. No stress!

  • Q.How long will I have access to the course videos and materials?

    A.You will have full access to all of the videos and materials as long as you have an active, paying subscription. All of the notes and materials will be downloadable. Note that you can only download the videos once you reach month 12 or if you purchase the full-access option.
