Adam Weismann

Adam Weismann & Katy Bryce work with lime and clay on a daily basis through their company, Clayworks. They learnt these skills through restoring ancient vernacular buildings in Cornwall, and then began to apply the traditional techniques and materials to contemporary ‘eco’ builds. They have a passionate belief in the power of using these natural materials to benefit the health and well being of people, buildings and the environment. Adam and Katy are the authors of Building with Cob and Using Natural Finishes for Green Books.
