Natural building exists from when humans started to settle down, away from the caves. Shelter making is an essential part of human life. It fulfils one of the three basic needs of food, shelter and clothing. The chapter explains how making shelter evolved with humanity, adapting to the needs and changes in surroundings. Thannal has tapped into resources from ancient textbooks and existing traditional homes to understand various traditional building methods. The elderly artisans and masons from different communities around the country play a crucial role in the learning process. They explain the techniques they practice, which they acquired from their ancestors, which help us connect the writings in the texts with the existing buildings. Making shelters with natural materials without causing much impact on nature was the practice of humans for centuries. Although there have been benefits and convenience to humans by changing into modern materials, one should not ignore the ugly damages caused by it. This episode aims to create awareness and strengthen the belief that building shelter without cement or steel is possible. Natural buildings are not alien to us but a necessity with humanity until a few decades ago. Let's watch the videos and see how the story is unfolding. References and links to additional learning resources are in the last section.
