In 1986, in Grenoble, France, earth architecture students from the CRAterre laboratory, engineers and masons, accompanied by their teachers, embarked on an audacious challenge: to build a house entirely out of earth bricks in just 24 hours.
More than a performance, it's a manifesto: learning by building, proving that earth, a material long considered archaic, can meet the challenges of emergency construction through a contemporary, ecological and economical project, capable of strengthening ties, passing on ancestral know-how and restoring the human dimension to the act of building.
Over the decades, the Maison en terre has become a veritable educational laboratory. Generations of engineers and architects fromUniversité Grenoble Alpes have experimented, tested and learned that it can contribute to a healthy building future.
In 2023, an experimental participatory building site will provide a remarkable thermal improvement using lightweight earth bricks made from local bio- and geo-sourced materials, giving a new generation of students hands-on experience of the challenges of contemporary renovation and construction.
The film traces this singular story, from the founding impetus to recent transformations. A human, interdisciplinary and intergenerational adventure, in which the land becomes at once a memory, a learning tool and a promise for the future.
