The Lotte Tower is situated in Sincheon-dong, Songpa-gu, Seoul, South Korea. It is also called Lotte World Premium Tower or Lotte Jamsil Super Tower.

After 13 years of preparation and obtaining permission in November 2010 to build the 5th tallest skyscraper in the world, construction began in 2011. After 6 years of hard work, the tower was prepared to open to the public. The tower was opened to the public on April 3, 2017.

The tower has 123 floors and is 555 meters tall, with a gross floor area of 805,872 square meters. The number is similar to the size of 115 football fields if compared. Astonishing, isn’t it?

The overall cost of the skyscraper was around 2.5 billion USD, but it was worth spending. In 2019, 13 million visitors came to visit the Lotte World Tower, making it one of the busiest areas in Korea.

The total cost of the tower accounted for about $2.5 billion. And by 2019, the tower has seen 13 million visitors a year.



The tower has also set numerous records:

  • It is the 5th tallest building in the world.
  • The 3rd tallest building in Asia.
  • The 1st tallest building in South Korea.

According to Guinness World Records in 2017, it holds records for:

  • The highest glass-floor observation deck.
  • The tallest double-deck elevator.

  •  The largest cinema screens.

Why is the lotte world tower important

Lotte Tower contributes significantly to the Korean economy. According to We Build Value, the Lotte World Tower has generated an economic return of $43 billion and created 10,000 jobs with a $2.5 billion investment. It’s not just a business project. It’s about boosting our country’s economy and giving back to our people.



The building’s design ensures that there are public facilities spread throughout, not just on the ground floor, to encourage people to explore higher levels. The top floors have restaurants, galleries, and an observation deck to attract more visitors.

The first ten floors have Lotte World Mall, with shops, entertainment, and cultural spaces. From floors 11 to 39, there are offices, conference halls, and event areas. Floors 40 to 75 are for office-tel (home offices), while floors 76 to 107 have a luxurious 7-star hotel.

The observatory, on the top floors, offers stunning city views. Also, the tower has the world’s highest swimming pool on the 85th floor and the world’s fastest elevator, taking you to the top in just 60 seconds.

The Lotte World Tower Design

The arechits of the tower is Khon Pedersoen Fox and Engineer is Syska Hennessy Group, and stractural engineer is L.E. Robertson Accociates.  The tower stands out in Seoul’s skyline because it’s not crowded by other tall buildings. Seoul is like a vertical city, different from cities spread out horizontally. The tower’s design, inspired by traditional Korean art like ceramics and calligraphy, brings a simple, elegant beauty to the city’s vertical landscape.

The tall building has a strong foundation, like a giant concrete slab, supporting its weight. It’s so hefty that just its concrete weighs seven times more than the Eiffel Tower.

Inside, there are important parts like the middle core, eight big columns, and special trusses. These columns, spread out around the edges, make the offices inside open and free of blocking views.

To handle strong winds and earthquakes, which are common in Korea, the building is built tough. It can handle winds as fast as 80 meters per second and big earthquakes, even bigger than what the Burj Khalifa can handle.

To make sure everything stays safe, there are over 400 sensors inside, checking for any movements or vibrations that could cause problems.


Despite the challenge of high carbon emissions from tall buildings, this tower prioritizes eco-friendly practices. It earned LEED Gold Certification in 2017, the first in Korea with over 100 floors to do so.

Renewable energy generated is equivalent to planting 8.5 million trees annually, reducing carbon emissions by up to 23,000 tons yearly. Innovative systems like displacement air and radiant floor cooling/heating save energy. A hydrothermal energy facility covers 10% of the tower’s needs, cutting energy use by 36% and carbon emissions by 38%.

An energy center on the sixth basement floor generates 12% of the tower’s energy through various methods like geothermal systems and wind turbines. Water-saving fixtures and greywater reuse save about 30% of resources.
