About CBT
This innovative building technique is healthy, ecological, energy saving and cheap. In our northern hemisphere climate the most appropriate materials are clay mixed with straw. Clay Build Technique only relies on the vast available amounts of this natural resource.
The tradition of using clay to build is as old as our culture and can be traced back to the Neolithic era, approximately 5500 years BC. One half of the world’s population, approximately 3 billion people on six continents, lives or works in buildings constructed of earth.

After the Second World War clay houses were successfully built in Poland. In the sixties, these houses still remained the only examples in Europe of building houses out of so called ‘light clay’ – clay mixed with straw. However, during the sixties, a fascination with concrete led to a rejection of clay buildings. Clay fell out of favour and was tainted as being a material for poor people’s houses.
