Lotte World Tower (Korean: 롯데월드 타워) is a 123-floor, 556-metre (1,824 ft) supertall skyscraper currently under construction[1] in the second-generation Lotte World complex in Seoul, South Korea. [1] Once completed, it will be the tallest building on the Korean peninsula, a title currently held by North Korea's Ryugyong Hotel.[2]

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 was observed at the construction site on March 2011.[4]

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.[5] Located near the Han River, the tower will contain retail outlets (floors 1-6), offices (7-60), residences (61-85), a luxury hotel (86-119), and public access floors (120-123) with an observation deck.

The tower is located next to the existing first-generation Lotte World complex which opened back in 1989, accessible via Seoul Subway Line 2 and Seoul Subway Line 8 on Jamsil Station.

Starting in June 2014, residents in surrounding neighborhoods began to notice small sinkholes forming and a nearby lake had been shrinking. The cause of this is unknown but authorities have said they are unrelated to the construction of the tower. However, an advisory team of lawyers, engineers, architects, environmentalists and university professors were asked to submit their opinions on the construction site, if there are any dangers to the tower, and to see if indeed the sinkholes are caused by the tower's construction.[2]

As of July 2014, nearly 70 floors have been completed.[2]
