Rob Hodgson and Kay Ralph plan to build an architectural monument high on a cliff top. They want to build a sleek glass-fronted house inspired by the cliff-top villas of California.
Their plot overlooks a beautiful National Trust beach in North Wales, but to have their jaw-dropping panoramic views will mean taking the biggest gamble of their lives.
Access will be incredibly difficult and expensive because of a low bridge over the narrow track to the site.
Erosion specialists predict their stunning new home could one day fall into the sea. Prohibited by the local council from reinforcing the cliff face, they decide to build anyway, believing at least the house will outlive them.
Grand Designs is a Channel 4 TV series covering unusual architectural house-building projects, presented by Kevin McCloud.
The properties featured in the series vary wildly from homes underground to converted water towers, with the only common factor being that they're all rather unusual or extravagant in some way.
