An Indian businessman has built the world’s most expensive home—valued at $1 billion, with three helipads, its own air traffic control, a six-floor car park, a staff of 600, a four-storey hanging garden and a cinema. The 173-metre tall mansion is called Antilia, after a mythical island in the Atlantic Ocean, and has just been completed after seven years of construction.
