I’ve applied cob (or clay or adobe) walls in my own hotel. Their advantage is that they excellently go together with wall heating. From that stems my interest in cob as a building material. 2/3 of the world population lives in cob. I started this series long ago with this post. I’ve now found a luxury cob vacation home in the UK, Bolton Percy Gatehouse, managed by the Vivat Trust. Worthwhile a visit so to see.
