I recently attended the 10-day Natural Building Workshop at Thannal Natural Homes in Tiruvanamalai, Tamil Nadu, India. I had a wonderful experience and learned so much about the principles and practices of natural building. The workshop was led by a team of experienced and knowledgeable instructors who were passionate about sharing their knowledge with others. They were patient and helpful, and they made sure that everyone had the opportunity to learn and participate.

No number of reviews can sum up the experience of learning at Thannal and the joy of natural building experience. Thannal is a reservoir of knowledge on natural building and the task they have undertaken to document and preserve our traditional knowledge on natural building is immense but also extremely critical. Biju Bhaskar and Sindhu Bhaskar are the real heroes of today and it was truly wonderful to be at the Thannal campus and learn from them. Their team is thorough precise and extremely patient. As a filmmaker with no knowledge of building, i cannot be grateful enough for the classes and lectures and all the material shared. Not to mention the camaraderie that sets in within the group in such experiences. It was my privilege to be taught by them and I am truly honoured to have been there and done that.

I've been to Thannal on a 10 day workshop. The workshop consisted of theory - practicals right from foundation till roofing. Thannal has designed this workshop so well. Being from non technical background I had lots of fun learning about natural building. Thannal campus has couple of natural buildings. Must explore this place. The staff is supportive in every aspect.

Being part of such natural building workshop was very satisfying. Eventhough I am a non technical person in terms of buildings, the theory and hands on experience gave enough confidence to build my own natural house in coming future. Biju Bhaskar and team are doing fantastic work in reviving natural building technique, hats off to them. This is the best workshop for those who would like to explore the natural building techniques.

The 10 days natural building workshop has been truly impactful. As an interior designer I feel responsible to carry forward these indigenous techniques and the journey of sustainable living. Thannal helped me to get out my connection with nature while working with mud. It’s remarkable how the combination of earth and other natural materials can result in beautiful dwellings. Great set of teachers, happy bunch of people, happy vibes & fuller hearts. Thank youuu 🤍
