Rob Hodgson and Kay Ralph plan to build an architectural monument high on a cliff top, a sleek glass-fronted house inspired by the 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 and worse still, the crumbling cliff on which they want to build is often exposed to tidal surges and winds of up to 100 mph. Erosion specialists predict their stunning new home should survive for between 60 and 120 years, but just as their modernist villa starts to take shape one of the biggest storms in recent history batters the coast.
