Question: are any buildings a mile high?
Answer: The current high-flying record holder is the Burj Khalifa in Dubai, at 2,717 feet, or about half a mile. Its successor, the Kingdom Tower in Jeddah, Saudi Arabia, will be the first building to surpass 1,000 meters or 3,281 feet when construction is completed in 2020. ... The same thing goes for the mile-high skyscraper.
