About the instructor- Sebastian, “The Wanderer Stuckateur” 

Sebastian Von Valkenstein is an experienced and skillful German ecological “Stuckateurmeister”, master of plastering. He has traveled all around the world as a “Stuckateur Gesellschaft Wander. A “Gesellschaft Wander” is a wandering journeyman who practices one of Germany’s most respected traditions of skill improvement and education during traveling, in Sebastian’s case plastering. According to the tradition which is kept until today, the journeyman has to set out to learn on his own from various masters from all around the world. This is how such a person completes his apprenticeship as a craftsman, improving his skills. They have a very specific costume and rules that they have to follow on their way, but the aim of the journey is to learn, gain, and to share their knowledge with people they meet on the way.


With over 12 years of experience Sebastian has worked in various ecological construction projects in several diverse countries, delivering ecological building workshops in Nepal, Austria, Romania, North Carolina, Canada, New Zealand, Germany and more. After mastering and working several years with his skill, Sebastian headed out into the world to broaden his expertise. During the last 4 years of his travels, he has learned various ecological techniques around the world and manages to use all of them to create a skill that is unique.


What you will learn

All our works shops are conducted in English with some flexibility in other languages. The workshop consists of both practical and theoretical parts. Guided by a master you will acquire traditional methods of ecological construction and building techniques. Participants will learn techniques on how to find and use local materials and how to build a sustainable and green structure without destroying the pristine surroundings. Cob (earth and lime) construction will be our primary focus. By learning the usage of traditional clay and earth techniques we make sure that we don’t disturb nature.

Participants will practice and learn with the master 3 hours in the morning and 3 hours in the afternoon. The rest of the time will be free, with an extra hour to discuss methods, ideas and share thoughts. It involves a fine mix of learning and enjoying nature during your holiday. The evenings will be spent sharing knowledge and experiences as well as playing music around the campfire in a multicultural group setting.

  1. cam scump, pentru doar 6 ore pe zi! interesul pentru astfel de tehnici este motivat si de lipsa banilor. presimt ca fotografierea si filmarea sunt interzise…

      Thanks for the comment! We try to make our prices low and accessible. Right now these fees are lower than the costs of most other workshops of the same kind for that lenght of time. Also please keep in mind that although the course itself has a 6hr structure you are getting a 24hr experience in nature in order to reflect upon the workshop lessons, network with others, and discuss ideas of the workshop. You have time to access our beautiful surroundings as well. Most people who are interested in ecological construction are not simply doing it to save money as they build a house, they are doing it so to save the earth and themselves by not having to support a massive commercial industrial system and to be more self reliant. We at the Organic Art Ranch live by a philosophy to encourage self efficiency while considering the environment as well as exploring the artist within you. I am not sure why you are assuming photos and videos are not allowed, again we do encourage any form of personal artistic expression and if Photos and Videos are your medium them we are all for it. We do however need to discuss ahead of time any Photos or Videos used for commercial purposes both with the Organic Art Ranch and with the Instructor of the workshop.

      Thank you for your interest. Unfortunately this workshop will be only in English, because it is the common language of all the participants including the teacher. However, we will have workshops in the future in Romanian as well, so feel free to check our website regularly.
