What does a future-proofed home look like? By Christine Ro Colin Heal's house is prepared for an uncertain future. The three-storey house in the village of Wheathampstead, about an hour's drive north of London, has 35 solar panels that produce more energy than Mr Heal and his wife can use, so they can sell surplus electricity. The house is fully electric. The couple plan to buy solar battery storage so that even more of their energy is useable. While flooding is a concern in the surrounding area, they don't worry about it - and not just because their house is on an elevation.
