In an episode centred on climate change and community resilience, Jo and Cathy stay in their local town - Todmorden - to chat with Barbara Jones, a pioneer of natural building methods. Sustainable materials including clay, lime, wool, wood fibre and straw as well as stone and timber come into their own. We find out practical steps we can all take in our homes, whether they are old or new, to improve breathability (thus minimising unwanted condensation and mould), reduce heat-loss, and shield indoor spaces from increasing outside temperatures. Barbara also tells the story of how the local college, condemned for demolition, was rescued by the community and is being transformed into a grassroots hub, sharing the skills and resources needed to take on the climate change challenge.
