Lotte World Tower (Korean: 롯데월드타워) is a 123-floor, 555-metre (1,821 ft) supertall skyscraper located in Seoul, South Korea. It opened to the public on April 3, 2017 and is currently the tallest building in South Korea, and is the 5th tallest building in the world.

History

After 13 years of planning and site preparation,[3] the tower gained final approval to start construction by the government in November 2010[3] and the first groundbreaking activities of piling and frame assembly were observed at the construction site in March 2011.

At New Year 2016 the LED-pixels of the facade showed "2016".[4]

On April 2, 2017, Lotte shot off fireworks to celebrate its official opening.[5] On Jan 1, 2018, Lotte shot off fireworks with LED laser show for 7 minutes to celebrate New Year's Day and the 2018 PyeongChang Winter Olympics.

Height

On March 17, 2016, prior to the final phase of external construction, the Diagrid lantern-shaped roof structure was completed. The roof structure was constructed with steel counterparts that are each 12 meters and weigh 20 tons. The counterparts were made up of bent metal panels that are 6 cm thick, and the structure itself is 120 meters high, and it covers floors 107–123. Approximately 3,000 tons of steel parts, a high-precision 64t tower crane, high-precision GPS alignment systems and highly skilled welding technicians were used in the construction of the roof itself. The roof structure is engineered to withstand its weight without reinforcing pillars, and endure earthquakes up to a magnitude of 9 under the Richter magnitude scale and winds up to 80 m/s.[6]

Floor plans

The conceptual design calls for a slender cone with convex, gently curved sides. An exterior of pale-coloured glass draws inspiration from Korean ceramics and features accents of metal filigree.[7] Located near the Han River, the tower is planned to contain retail outlets (floors 1–12), offices (14–38), residences (42–71), a luxury hotel (76–101), private office (105–114), and public access floors (117–123) with an observation deck.

Main facilities

Seoul Sky is located on the 117th ~ 123rd floors of Lotte World Tower in Sincheon-dong, Songpa-gu, Seoul, Korea. The 117th floor consists of the entrance floor, the view floor, the 118th floor is the entrance floor, Sky Friendly Cafe, Sky Terrace, Photozone on the 119th floor, Seoul Sky Cafe on the 122nd floor and 123 lounge, which is a premium lounge bar on the 123rd floor. It is the second highest in the world, followed by the Shanghai Tower (located 546 meters high and 118 stories) in Shanghai, China, and the highest in the OECD countries. There are four media stands on the 117th and 118th floors. People can see the scenery of Seoul city with a glass bottom and a telescope. The sky skylight of Seoul Sky is the highest glass floor observatory. Lotte Tower and One World Trade Center have concluded an operation and technical service agreement.[8][9]

Urban exploration

In 2016, two Russian and Ukrainian urban explorers, Vadim Makhorov and Vitaly Raskalov from Ontheroofs, illegally climbed the under-construction Lotte World Tower through stairs and Vitaly Raskalov then free-climbed up the crane on the tower's top.[10][11] The video was viewed over 3 million times as of September 2016 and received worldwide media attention.[12][13] Following the climb, Lotte World Tower released posters with the photos of Vitaly Raskalov and Vadim Makhorov and banned them from the building.[14][15]
