A competition to design the new Istanbul control tower captured the hearts and minds of designers around the world - and construction is similarly interesting investors, who are buying swathes of land around the airport. Investors are well aware of the knock-on effect the airport will have: pushing prices up and attracting more and more tourists to the city which already hosts 13 million visitors a year, making it the fifth most visited city in the world. The airport will serve up to 200 million passengers a year, making it the biggest, busiest airport on the planet.
