The perfect James Bond villain lair? An incredible house has been built into the interior of a coastal cliff. Called NCaved, the property is situated on a 6,000m2 site at a small secluded rocky cove on the Greek island of Serifos. NCaved was designed by Athens-based mold architects, who say their creation is "seemingly hovering just above sea level”. The designers have likened it to a "Three-dimensional ‘chessboard’ of solids and voids.” Iliana Kerestetzi, Mold Architects founder, says: “The house was created for a private client. We sold the land and then designed and built the house for him."
