On April 2, the Lotte World Tower opened in Seoul, South Korea. Designed by New York–based firm Kohn Pederson Fox, the tower stands at 1,820-feet-tall and is now the tallest tower in South Korea and the fifth tallest building in the world. The tower features a double-decker elevator—the Sky Shuttle—which can take visitors from the basement to the 121st floor at 33 feet per second. Manufactured by Farmington, Conn.–based Otis Elevator Company, the elevator can hold up to 52-people per cabin with virtual tours of Seoul displaying on 15 OLED screens during the 1-minute ride up the skyscraper. "A double-deck elevator was used because the observatory would be crowded at certain times of day," manager of Lotte Corporation Wonixuk Choi said. Construction for the tower took six years to include a parking lot, podium, office spaces, residential space, the Lotte Hotel, private offices, and an observation deck.
