Mud is not built in one go — it is built one course at a time, each waiting for the one beneath it to dry.
Editor’s note: this is display material. The video is replaced with a link to the actual documentary from the post edit screen.
This short film records the stages of building a mud wall: choosing the soil, mixing it with straw, leaving it to cure, then raising it course by course.
Why straw?
Straw reduces cracking as the clay dries by distributing the shrinkage across many fibres instead of letting it gather in a single split. Practical knowledge that preceded the engineering explanation by centuries.
Waiting is part of the technique
The most telling thing in the film is not the movement of the hand but the pause: each course waits for the one beneath it to dry. Building here obeys the rhythm of the climate rather than a work schedule.
