About this programme

7/8. Kevin McCloud charts the progress of Helen Gould and Phil Reddy, who want to build an environmentally friendly dream house in Cumbria, which will be almost completely covered by earth and boast a south-facing frontage built entirely of glass. The couple have a budget of £220,000 and a 22-week deadline, but the presenter is unsure whether they can deal with the problems of waterproofing and light sources before the arrival of their first baby.
