Is your house boosting your health? Sophie and Kate tour the home of Oliver Heath, the expert in sustainable architecture and biophilic design. They find walls that make you live longer, a bed to help you sleep better, plants to cleanse your air... and a floorplan which harbours the secret of human happiness. No, really.

Useful links and images are supplied on each of Kate and Sophie's blogs, and do join The Great Indoors Podcast Facebook group.
