Property Update: Green and affordable

HOME buyers who would like to be green often cannot afford the insulation and special materials. But a new estate in east London boasts low costs and ecological correctness. Buyers from Tower Hamlets' waiting list paid from pounds 39,600 for a one-bedroom flat to less than pounds 80,000 for three-bedroom houses in Bethnal Green - 30 per cent less than normal market values. The locally based Environment Trust has created homes which offer 70 per cent savings on heating and water bills, on land that had been derelict for 30 years.
