James meets Maggie, who is determined to decorate her 1930s house using eco-paints, whilst restoring and reusing the original features. In Northampton, we meet Julie and her Dad, who with Dick's help, install a solar panel on the roof. We return to the Keenans on the Wirral. The guest wing of their big eco-build is nearing completion. They get stuck in and learn how to use environmentally friendly lime plaster.
