Straw, Circularity and the One Question Nobody’s Asking

How do we make circular construction scalable and healthy homes the new normal? In this episode of the Thrive in Construction Podcast, Darren Evans brings together three leading voices shaping the future of sustainable building: Chaline Church (540 World & Cradle to Cradle Partner) Oliver Novakovic (Technical & Innovation Director, Barratt Redrow) Paul Lynch (EcoCocon, Finland-based natural building pioneer). Together, they explore the real-world barriers and opportunities to embedding circularity, regenerative design, and healthy materials into mainstream construction. It’s a dynamic, honest, and solutions-driven conversation that cuts across design, development, manufacturing, and human health. Key Highlights • Cradle to Cradle Thinking – Chaline Church explains how material health, social fairness, and full circularity can transform both people and the planet. • From Concept to Construction – Paul Lynch shares how EcoCocon builds large-scale modular homes from straw and timber — fast, healthy, and fully certified. • Innovation at Scale – Oliver Novakovic discusses how Barratt Redrow is tackling net zero, supply chains, and real-world testing through 52 innovation projects. • Bridging the Gap – The guests tackle the disconnect between ambition and delivery and why storytelling, trust, and collaboration are key to real change. • Healthy Buildings = Healthy People – Why offgassing, acoustics, light, and authentic materials directly affect wellbeing, focus, and long-term health. • Regenerative Farming & Circular Supply Chains – How straw, hemp, and bio-based materials can feed both housing and soil health, reducing carbon while improving ecosystems. • Reframing ‘Sustainability’ – Why the word itself may be losing trust and why ‘health’, ‘quality’, and ‘legacy’ might be the language that moves people to act. This conversation is essential for developers, architects, manufacturers, and sustainability leaders who believe the next revolution in construction won’t just be about carbon, it’ll be about people, materials, and mindset.
