Build and design in a more sustainable way for future generations? An ecological bias defended by many builders around the world. Determined to draw inspiration from nature to imagine architectures with irreproachable ecological standards, these pioneers are also keen to pass on their commitment to as many people as possible. In the heart of the French countryside, in the Corrèze department, a wooden house inspired by yurts, these round habitats of nomadic peoples, was created to face the spatial and environmental constraints that surround it. But to start our journey, let’s travel to the Indonesian island of Bali where the Green School has been named the greenest school in the world. Planted in the middle of rice fields, the place stands out as a virtuous model both for its eco-construction respectful of nature and its alternative education system ever closer to the environment.
