In our 2-day hands-on workshop hosted by the Thannal Team, you will immerse yourself in actual building projects under expert supervision. This workshop offers you the opportunity to become part of a community passionate about natural building, just like yourself. Additionally, you gain exclusive access to an online course that provides comprehensive knowledge on various aspects, from selecting the right materials to applying the final touches to a building. It’s also an excellent opportunity to connect with individuals who can support your projects, including volunteers, architects, and engineers.

For this enriching 2-day journey in natural building, your mentors will be the formidable pair of Architect Biju Bhaskar, who brings 15 years of expertise, and his wife, Sindhu Bhaskar. Accompanying them is Architect Dharan Ashok, enriching the experience with his fresh perspective and 5 years of experience in the field. Beyond these expert guides, you will also gain insights from local villagers and skilled masons. These practitioners, with their hands-on experience in Thannal projects, will share their valuable and practical knowledge with you

While the course duration in natural building varies, it’s important to note that even a 2-day hands-on program can be incredibly effective. This is especially true when paired with the complete Part 1-4 online course. Impressively, there are individuals who have successfully built homes after attending just the 2-day session. However, for those who seek a more immersive, hands-on experience, opting for a 5-day or 10-day program may be more beneficial.

If you have previously purchased the Part 1-4 online course and are interested in the new program, you can still participate in the hands-on workshop. Existing online course users are welcome to join by paying a fee of Rs. 8,000. This option allows you to expand your learning experience with practical, hands-on training.

Two day workshop at Thannal was really an exemplary and memorable experience. For long I had wished to meet Mr.Biju Bhaskar,the soul of Thannal and learn from him directly and for me it was a dream come true. Mr.Dharan ,who headed the workshop most of the time handled the sessions in a much professional and gentle manner. Though too short,the confidence that we get out of this workshop is that high that it enables us to try a mudhouse of our own or teach the technology to like minded people. Two lively days with hands on experience and crisp theory sessions were really worthy. My wishes to Thannal and team in their future endeavours. Man comes from mud and goes to Mud..,..

Thannal's workshops has helped me gain more technical as well as theoretical knowledge about natural building. Their stories and history regarding mud houses is not just about "alternative buildings" but the real deal for a sustainable future against cement. Anyone who visits Thannal is assured to come back with an open mind and filled with determination to start building their own homes! Just listening to what the people at Thannal share you too will be motivated to learn more about natural building.

It is very good, Real Earthly experience and teaching and hands on are superb, dharani, Biju sir and their team was fantastic, supportive, patient enough to listen to our questions and answer them till we understood. There is no hype and the course is really real. I suggest most people should visit thannal and come into this natural building method which benifit us financially, in being more,healthy and also friendly to mother nature.

Back from a recent 2 day common-man 'Natural Building' workshop as a family, it felt we where in another world. Where your living space can be built with your own hands with what nature offers you so humbly...you are not put down by the thoughts that you don't have a formal learning or a big budget. Every piece of information was offered in such an order, in a language that even a layman can relate, understand and learn. The workshop was a good blend of theory, hands-on, personal experiences and stories, history, the present scenario of development and its impact, music, sweat...so much and more. Yet, you are not mentally drained (physically, maybe) instead rejuvenated seeking for more. Holding a high regard for every member of Thannal for their knowledge, efforts, dedication and contribution to this essential field, especially when so much is happening in the name of development around us. My sincere gratitude for the experience.

I am a software engineer and was looking out to learn about natural construction and came across Thannal. I would say this is one of the best place to learn about natural construction. They have knowledge of natural construction in and out and it’s not just theoretical, Thannal has been putting it into practice for years now. I attended 2 day workshop and in two days I was taught many things with fine details. My questions were even answered to a great satisfaction. I am very thankful to Biju Anna for taking this initiative to restore our faith back in natural construction by showing the application of it. Also, thankful to Dharan ji for answering each and every question during the workshop and explaining things with finer details. Thank you very much.

A beautiful place to learn natural building and other sustainable options.Being a person to build a natural home this was the apt place to learn all the methods of home building with mud, lime and bamboo.Loved the way how they explained and showed how to do it by ourselves.Literally shocked by the strength and durability of the walls n floor using such simplistic raw materials like mud and lime.Looking forward to learn more such techniques and I was glad to have my kids with me to have this beautiful experience of building a home of their own.
