Lotte World Tower

The 123 floors of the Lotte World Tower, designed by Kohn Pedersen Fox Associates, were Korea's first 100-story structure. As the steel structure rises, it curls inward, and the glass utilized was intended to serve as a nod to Korean ceramic tradition. The skyscraper is filled with a combination of retail, office, hotel, home, and event space.

The Lotte World Tower is a Seoul landmark and Korea's first 100-story structure. It was the fourth-highest tower in the world when it was built, and the highest in the OECD countries. A thin cone with convex, slightly curved sides is the conceptual design. The pale-colored glass exterior is inspired by Korean ceramics and incorporates metal filigree details.

The 117th to 123rd floors are home to Seoul Sky. The entry and view floors are on the 117th floor, while the Sky Friendly Cafe and Sky Terrace are on the 118th floor. The Photozone is on the 119th level, the Seoul Sky Cafe is on the 122nd, and the 123 lounge, a luxury lounge bar, is on the 123rd. On the 117th and 118th levels, there are four media stands. The view level features a glass floor and a telescope, as well as spectacular views of the city. As of the tower's completion, the skylight of Seoul Sky was the highest glass floor observatory. An operating and technical service agreement has been reached between Lotte Tower and One World Trade Center.
