OVER ONE THIRD OF THE WORLDS POPULATION….
APPROXIMATELY 3 BILLION PEOPLE ON SIX CONTINENTS….
LIVES OR WORKS IN BUILDINGS CONSTRUCTED OF EARTH.

Established in 1994, EARTHA was formed with the aim of fostering the cause of clay building in East Anglia. Within the region, there are thousands of examples of clay built structures, whether that of domestic dwellings or civic buildings. These heritage buildings are mostly examples of the Wattle and Daub technique, and Clay Lump.
Due to the unique qualities of clay, along with many other natural building materials, these historic buildings still stand strong. We therefore think it is necessary to promote and conserve these structures the best we can for future reference.

An example of wattle and daub. Replacing the split hazel (wattle), and using clay render (daub) to patch in. The old daub can be recycled and re-used.


We would like to preserve examples of these building techniques for years to come, to highlight the many beneficial properties of living in and building with clay, along with many other earth build materials.
By looking at the historical uses of clay technology, for which examples go back thousands of years, we want to embrace the future of clay in construction, so to provide a more sustainable, low impact and healthier means of development today.
What we do
EARTHA is a platform for individuals and companies to express their interest in all things earth building, and to help to share knowledge and information within the earth-building community.
We are here to help connect people and businesses with earth-based construction and conservation services within East Anglia.
As a Community, EARTHA hopes to continue to keep alive earth building practices akin to East Anglia, and to so many properties that exist within the region.
Demonstrations, hands on workshops, and on-site training sessions are held during the warmer months at various locations throughout the East Anglian region. These cover the two principal forms of clay construction of Wattle and Daub, and Clay Lump.


We also hold Conferences through the year, our most recent, ‘The Future is Earth’, was a full day event, held at The Gamekeeper, Old Buckenham, Norfolk. Guest speakers, Anthony Hudson (Hudson Architects), gave a brilliant and insightful presentation on the domestic CobBauge House in Fakenham, and Will Stanwix (The Hemp Block Company), discussed with us his personal and professional progression, development and testing of natural, sustainable building materials.
