Transformation Is Personal, Not Just Technical

In this episode, Professor Jo Patterson (Cardiff University) shares how the Transforming Homes project is revolutionising retrofit by combining low-carbon technologies, recycled and bio-based materials like hemp and timber, and most importantly — the voices of residents. 

Key takeaways: 

• True transformation goes beyond carbon savings — it’s about healthier, happier residents. 

• Co-design matters: residents help reimagine their homes, busting myths and strengthening communities. 

• Bio-based materials face barriers: perceived risks, compliance challenges (e.g., PAS 2035), and slow adoption — but persistence is key. 

• Communication and trust are critical — from installation to long-term success. 

• Health impacts: improved asthma symptoms, better school behaviour, lower stress levels. 

• No two homes (or families) are the same — scalability requires data, flexibility and expertise, not cookie-cutter solutions.
