About this programme

7/12. Kevin McCloud meets Claire Farrow and husband Ian Hogarth, who are trying to build a home containing a sauna, spa, dance floor and DJ booth on a small patch of land in London. They have applied for planning permission to include a basement and started work on the construction, but setbacks, including their digger smashing into a neighbour's wall and the re-emergence of the old river under the building, threaten to prevent them completing the project.
