Rammed Earth Workshop in Yazd
Three days of hands-on work with architecture students building rammed earth walls from local soils.
Together with an architecture school in Yazd, we ran a three-day workshop for thirty students.
From soil test to wall
The first day was spent understanding soil: simple field tests to establish the ratio of clay, silt and sand. Students learned how a small addition of lime raises a wall’s strength.
Over the next two days a three-metre sample wall was built in timber formwork, its coloured layers showing the different soils around Yazd.
Why earth
Rammed earth has very low embodied energy, is available on site and offers high thermal mass, ideal for a desert climate.
The sample wall remains in the school courtyard so its behaviour can be followed through the seasons.
