Basic Carbon Accounting for Buildings Webinar
March 5

The up-front carbon emissions from buildings – often called “embodied carbon” – is getting a lot of attention recently.

Cob Oven & Benches
June 28 - July 5
Placerville, California

We will be building a community-size cob oven for baking everything in.

Natural Building Course
August 1 - 8
Portugal, Fundao, Mount of Oaks Community

My focus is always the teaching and the participants, so we will not attempt to finish a particular building, as I ve learned from other Course's experience that that is not the best approach as 8 days is a very short time.
Yet, every course the participants get amazed with how much they achieve in 8 days as you can see in the videos. The goal is also for each participant to be part and see the progress of at least a wall, if not more, depending on the design and ability of the group.
The Course will include basics of DESIGN and Sustainable building, FOUNDATIONS ( more visual and theoretical, as it’s very hard labour to dig and move gravel, and that can be easily explained), STEM/support wall ( SUPERADOBE), WALLS of different techniques ( WATTLE and DAUB, CORDWOOD/COB, STRAWBALE, LIGHT EARTH as insulation), EARTH PLASTERS, LIME PLASTERS, LIME wash with coloured PIGMENTS, and other natural finishes.
I've also made a MANUAL, which is also in PDF form and it will be sent to each participant at the moment of REGISTRATION. Itaddress each subject in a mind map style, just to help the participants take their notes on my handmade scribbles and drawings :-)

Hybrid Straw Bale/Cob Tiny House
August 2 - September 13
Pietris, Romania

We will be building Sarai, Aurel and Isarin’s 25m2 home.  While this size is about double or a little less than what we normally build in our 5-week workshops, we have decided to adjust some elements to be able to complete the building in 6 weeks.  The workshop will be considered an Intermediate Cob Building Workshop because the foundation will be built ahead of time, which will save us 2 weeks!  When students arrive the foundation will be completed and ready for cob. Many students prefer this as the foundation is alot of heavy work and can be built by professionals as well.  Students, as always, will still learn about Foundation in the lecture but not build it.  Since the foundation of a cob building is not special to cob, you can have anyone build a foundation who knows how, but what IS special is how the connecting surface is finished, which we will explain and you will see before we add the Cob.  The workshop thus will focus on Cob and Straw Bale walls (50/50), and students will get to learn both systems in what we call a Hybrid System and how they connect, plus floor, plaster and Reciprocal Frame Green roof.  We will also build a Sara Adobe Masonry Heater during one of the weeks. 

Students will learn ALOT by building every day with continuous instruction both practical hands-on and theoretical using lecture time, slides and videos.  You will leave fully confident to build your own cob house or someone else’s, which is your next step after graduating from our training!  This will take you to the next level of understanding and experience after which you can be a competent cob workshop assistant and builder.

Cob Cottage
August 9 - September 6
Mesa, Colorado

The workshop students will be building the stone foundation and walls of a personal retreat cob cottage for the Center.  Students will receive the Intermediate Cobber Certification for foundation, walls, floor and plaster.  The size of the cottage will be around 120ft2, depending on size of workshop.  The foundation will be built in Week 1 from the local rock on the land using lime and sand mortar.  On Day 5 we will pour the first layer of cob floor over tamped gravel and insulation.  In weeks 2 & 3 we will build the circular Cob Wall with opening and fixed windows, niches, shelves, bottles, other useful natural elements inserted into the wall for hanging art work and clothing, electrical outlets and housing, and the roof connection.  At the end of week 3 we will sculpt the wall and in week 4, we will plaster the wall and finish the second floor coat. Students will learn ALOT by building every day with continuous instruction, both practical hands-on and theoretical using lecture time, slides and videos.  You will leave fully confident to build your own cob house or someone else’s, which is your next step after graduating from our training!  This will take you to the next level of understanding and experience after which you will be a much more competent workshop assistant and builder.

COB Building Workshop
August 26 - September 4
Nagydobsza, Hungary

I've invited Maiana Barrass from France to share her knowledge and wisdom with women who have an interest in the transformational healing work that can occur when we work together as a sisterhood. Together we will create a beautiful, peaceful sanctuary in nature, a small meditation room in the Enchanted Garden. When you build consciously and set an intention for your build, magic happens. It creates the opportunity for deep inner healing and transformational work to take place. Maiana will teach you how easy it is to build a cob structure by hand – from start to finish. 

A structure that will give you a sacred space. One that you can build in your own back garden. A space you can use just for you, be it for healing, meditation, an art room or music room. Built the feminine way; the way our ancestors built, without the need for machines or fancy tools. Women are the nest builders after all! Using ancient divining methods, our hands and feet, intuition and body wisdom, we will co-create an approx 8ft-diameter round cob structure that will be used as a personal development, healing and meditation space. This template will allow you to build your own space to a size that suits your own needs, with your own dimensions.

Intro to Lime Plaster & Tadelakt
October 24
Peterborough, ON Canada

Lime has been used in plasters for thousands of years, and it is highly valued by modern plasterers for its balance of weather resistance, permeability, strength and flexibility. It is very versatile and can be used in thick base coats and fine polished finish plasters. It can also be perplexing, with a variety of types of lime available, and chemical reactions occurring between lime and clay or other mix materials. Black soap applied to the surface of a lime plaster can add shine and water resistance –  this is the key to tadelakt, a polished waterproof lime plaster originating in Morocco, but it can be used on other lime finishes. This workshop explores the types of lime and how they can be used in base coat, finish, and fine finish plasters. The morning will mostly be focused on theory and types of mixes; in the afternoon students will have an opportunity to apply some finish plasters on sample boards, and get a taste of tadelakt.
