Advanced Cobber Certification: Complete Hybrid Cob/Straw Bale Home and Masonry Adobe Heater in Romania

August 2, 2020 - September 6, 2020










This will be CruzinCobGlobal’s first Romanian workshop and this is a special one because my grandparents on my mother’s side were Romanian Jews! Which explains alot, right? At least my three sons understand why we feel “different” than everybody else. The Gypsy Blood must be in that mix somewhere!

Our wonderful hosts are a sweet young family that just gave birth to their first son Isarin on August 13th! Sarai, who has Nigerian, South African and Romanian roots and her Romanian partner Aurel have been dreaming of their future Cob Home for a loooong time. Here is their story:

After leaving behind everything in their birthplace, Bucharest, Sarai and Aurel embarked on a soul searching journey to India. To be lost and to find the self again. They had no set intentions, neither of staying for a certain period of time nor of necessarily returning home.

This experience would truly be an unpredictable one taking them from central India to the east coast, up to Calcutta and right across to the west coast. But after three months of wandering and meandering, a certain piece of the puzzle kept showing itself in one form or another. That precious piece took on the shape of a small village in the central mountainous region of Romania where Sarai’s grandfather was born. Here, in a valley between the hills surrounded by the Oriental Carpathian mountains, lay a picturesque terrain encompassing a hill of Black Locust Acacia trees, and an apple orchard ending on the banks of a stream shaded by three majestic walnut trees. This is where we will build their home.

And so in searching far and wide they found themselves on their way back home, a home they had never known. Aurel and Sarai were just two months away from welcoming their firstborn when they finally found a house to rent in close vicinity of their land where their home will soon come into being.

We invite you to embark on this continuing transformational journey and take part in building this sacred space that Aurel, Sarai and their baby boy Isarin will be calling home.

Aurel after dabbling in logistics and carpentry, took up working as a chef and continued till leaving for India. He started off as a raw vegan chef and then went on to fusion cuisine while traveling through Germany and England. He now continues as an experimental chef for his family and will have the pleasure of applying what he has learnt along the years to the cob workshop menu.

Sarai worked as an early childhood teacher in non-formal, experiential education. For this reason we will be offering childcare possibilities with one of Sarai’s colleagues.

Surrounding Pietris is an abundance of hikes and nature walks offering the possibility to visit such places as the National Park of Calimani where, besides the marvelous scenery of the largest volcanic complex of the Carpathian Mountains, one can see caves formed by volcanic eruptions 5 million years ago, Tihu Waterfall, the unique rock formation of The 12 Apostles, the lake Iezer, Scaunul Domnului (Lord’s Seat) and the highest peak Pietrosul Peak of 2100 m.

For a more relaxing option, just one hour away by car you can visit the Turda Salt Mines. Here, after a week or more of joyous cobbing, you can relax at the wellness and spa center that has various treatments on offer for very low prices.

Two medieval cities about two and a half hours away by car are Sibiu, that was declared the cultural city of Europe in 2007 and Cluj Napoca, the capital of the Ardeal Region, an important cultural, economic and universitary center of Romania.

In the months of August and September temperatures vary from a maximum of 30 degrees celsius to a minimum of 24 degrees celsius in the evenings. Days are mostly sunny, rainfall occurring very rarely. Evenings mosquitos are encountered so repellent can help.


We will be building Sarai, Aurel and Isarin’s 15m2 cottage.

This Advanced Cobber Certification training offers a complete foundation to roof build over a period of 5 weeks. The foundation and first floor coats will be built in the first week from the local rock on and near the land using lime and sand mortar.  In weeks 2-4 we will build the circular Cob & Balecob Wall with opening and fixed windows, niches, shelves, bottles, other useful natural elements inserted into the wall for hanging and also attaching things, electrical and plumbing fixtures and pipes/housing, and the roof connection.  We will also be sculpting and plastering the wallsin Week 4. In Week 5 we will build the Roof, the Heater 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.



This Intensive 35-day Advanced Cob Building Workshop consists of theoretical instruction (lectures with graphics) and construction for 4 hours in the morning and 3 hours in the afternoon.  Students arrive on Sunday, August 2nd, and settle in. The workshop begins at 4pm with an Opening Circle, a Host Site orientation and Introduction to the Project.  Dinner is served at 6pm and followed by an Introduction to the Workshop.  Monday morning we begin digging the trench for our Cob Building!!!!

Following Breakfast, the morning session lasts 4 hours with a 20-minute snack pause. Lunch break lasts 1.5 hours which includes rest time before the 3-hour afternoon session begins. There will be a daily 60-minute lecture either after lunch or after dinner on most days. After class in the afternoon there is a 90-minute break before dinner, in which students are encouraged to stretch, do yoga, relax. There is often someone officially or informally leading yoga or some other movement practice in the morning and/or afternoon.  There will also be a few evenings after dinner for showing slides, videos and having Course-related discussions.  Most evenings are free and sometimes other students offer informal courses in their specialties and passions.

This 35-day Course will offer practical learning by building a complete 15-18m2 (depending on number of students) curvilinear building from foundation to roof, as described in the “Project” section above.  Those who complete the Workshop will receive an Advanced Cobber Certificate of Completion for Foundation, Cob Walls (which includes Door, Windows, Shelves, Art, Electrical & Plumbing), Floor, Plaster & Roof.




The Advanced Cob Building Workshop begins on Sunday, August 2nd 2020 at 4pm with the Opening Circle and Introduction to Site & Project, the Welcome Dinner and Introduction to the Course.  It ends on Sunday, September 6th, 2020 after the Closing Circle & Lunch.

The workshop will complete Foundation and then 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 the last week.  This usually takes one day because the adobe blocks are prepared ahead of time.


In Week 1 we will build the Foundation and pour the Base Floor Coat on Friday (gravel, insulation and cob with radiant floor heating tubing for those cold Romanian nights).  In Weeks 2 & 3 we will build the cob and straw bale wall and in Week  4 we will sculpt and plaster and build the Sara Adobe Heater.  Finally in Week 5 we will build the Reciprocal Green Roof and finish the second floor coat.

For people who still want more….this workshop will be followed by a Cob Oven & Benches Workshop for another week of easier-going building and lots of creativity!  Students who want to do both will receive a 10% or 50€ discount on this workshop.

These workshops are designed for people that want to learn how to build a complete structure from start to finish in a professional manner and amount of time. They are very intensive and, while we make time for yoga, stretching, dancing, music, relaxing….all students are expected to be present and participating in all building/learning hours unless ill or have some other significant reason. This is because we design the size of the building and organize the structure of the workshop in accordance with the number of students and when people are absent it impacts the whole group and the other students have to work harder. In addition Instructors try to set up building work according to students’ preferences and learning needs.

That being said, the workshop intensity also changes from week 1 to week 5. The first foundation week break speople in with the challenging work of moving rocks and fitting them together in a harmonious strong structural system to support the heavy cob wall and roof. The floor days are a change of pace with shoveling, moving and pouring endless wheelbarrows of heavy gravel, followed by lighter insulation and then again endless heavy cob mixes made and poured and levelled.  Very satisfying work and thankfully can be very fun as a group with loud funk music to fuel the fire.



In the second and third weeks, a first for CCG, we are now lifting and moving bales, about 15, into place, and cobbing them in as well as preparing to connect them to the cob wall and building the cob wall at the same time. This should go quickly and cleanly and should be enjoyable to see the walls go up fast!

In the fourth week the rhythm slows down and the body can rest as students tap into their creative source and design and sculpt the walls and around niches, shelves, windows, etc.  Plastering follows sculpting and is also an enjoyable lightweight physical experience that lends itself to talking and sharing at the wall in a meditative rhythm as the students have bonded and shared deeply through a variety of experiences for a month. In the final stretch there is always a boost of energy to wrap up the build as we move into carpentry and power tools and lots of hammering to create the strongest and most beautiful roof there is, the reciprocal roof.  We will complete it with a green covering.  The Sara Heater will be completes simultaneously and the grand finale is the final floor coat on the last day.



For students wanting a more mellow slow-paced cob experience along with time for personal exploration and experimentation, these workshops are not for you. However you can find a more suitable workshop online that is usually for a shorter period building a garden wall, a bench, a compost toilet or some other small-scale project.

Students are required to read “The Hand-Sculpted House” by Ianto Evans and Linda Smiley before the workshop begins and any other book they find, as well as watching videos on YouTube, especially the ones posted on CruzinCobGlobal’s website under Gallery to get an idea of what is expected. Please bring your book(s).


Students must tend to their own personal needs, drink alot of water, rest when needed and exert themselves at a steady pace. Students who cannot do the strenuous physical work should let us know before the workshop begins so we can adjust appropriately. It is totally OK to come for the lecture/theory part, and then help the building part in less physically demanding ways, ie cutting straw, sifting for plaster, hammering nails into frames or shelves, sculpting, plastering, cutting bottles. There is alot to do besides making and building with cob!!Finally, please bring a watch or use your phone to be prompt and ready for each part of the Course including meals. Feel free to share your dietary needs (not preferences) with CCG or the Host and bring your special snacks and foods, pillow and whatever you NEED to be comfortable and happy. Feel free to also bring slides, videos, movies and books to share, as well as a sample of your soil to test. And favorite music playlists please!!!



Petris is easily reached by train directly from Bucharest, the international airport you will need to fly into if you are coming by air.  The train station Deda is only 3 km away from the building site. The ticket costs 17 euro and takes about 7 hours. From the train station you can either get picked up by Sarai and Aurel or jump on a minibus for about 50 euro cents and you will have arrived!




Students will be fed 3 high-quality prepared delicious meals a day during the weekdays.  CruzinCobGlobal hosts always serve amazing food to cob students in gratitude for their hard work! Since this is Romania there will be fresh and amazing vegetarian food, which will be the basis of our menu.  Students that have non-vegetarian requirements can bring personal items to complete their diet and other requirements can be presented to the cooks a month before the start date so they can make sure to have what is needed.  We will try to meet people’s requirements of course so it is important to communicate them as soon as possible. Meat or fish  may be served once a week depending on students’ interest and availability. On weekends,


students onsite will be provided with food to make breakfast/brunch and can explore and enjoy the region’s offerings for the other meals!!!

Students will be camping onsite with simple and rustic facilities like compost toilets, hot and cold outdoor showers, an outdoor kitchen & dining area, a yoga/dance space and a cozy hangout communal area with fire circle.   There are many cafés nearby for wifi use and with a SIM card students can have service onsite.
