THE WORLD'S MOST EXPENSIVE APARTMENT
When completed, it is expected that The Sky Penthouse in Monaco will become the world's most expensive apartment, going on the market for just under $400 million USD (approx. £240 million).
At 35,500 square-foot, the penthouse will be spread across five storeys and will feature unbeatable views of the coastline from its floor-to-ceiling windows and large terrace with swimming pool.
Luckily for the developers, nearly 30% of Monaco's inhabitants are millionaires, so there shouldn't be a problem finding a buyer.
