Turf is an underappreciated renewable building material. Training staff from a permaculture eco-farm in turf building based on archaeological evidence will create deep impact via a hands-on, learning-by-doing exercise. Their new knowledge and skills will inform the farm’s eco-business development plans to act as a local multiplier for this impact. Engaging local and national heritage educators and conservation managers with the good performance of turf constructions in rural settings and the material’s role in sustainable agricultural cycles will directly inform reconstruction projects currently in planning by heritage agencies, and multiply the impact by informing the development of new education resources and best-practice guidance and policymaking.
