Lotte World Tower in Seoul is a supertall skyscraper that has reshaped the city’s skyline with its slender, tapered profile and a mixed-use stack of offices, residences, hotel rooms and public spaces. Completed in 2016 and opened in 2017, the tower reaches an architectural height of around 555 m (1,821 ft), making it the tallest building in South Korea and among the very highest structures worldwide designed for daily use.
A vertical city in Songpa-gu
Lotte World Tower stands in the Songpa District on Olympic-ro, close to the Han River and the extensive Lotte World entertainment and retail complex. The project was designed by Kohn Pedersen Fox Associates (KPF) in collaboration with local partners, creating a 123-storey tower above ground with additional basement levels that integrate the building into the wider urban fabric.Kohn Pedersen Fox Associates The sleek exterior tapers as it rises, giving the building a distinctive silhouette against the low-rise neighbourhood and the distant mountains.
The tower’s mixed-use programme is stacked vertically, with retail and entertainment facilities in podium levels, offices occupying sections of the middle floors, and a high-end hotel and serviced apartments higher up.Floors above ground Above the private uses, the upper storeys are set aside for public attractions, culminating in the Seoul Sky observatory close to the very top of the structure.
Seoul Sky: an observatory in the clouds
The Seoul Sky observatory occupies the uppermost floors of Lotte World Tower, from level 117 up to level 123, and is one of the highest observation facilities built inside a skyscraper. The main enclosed deck sits at an elevation of around 499 m (1,637 ft), with glass-lined spaces that wrap around the core to give continuous views over the city and the Han River basin.main observatory level On clear days, the sightlines extend across central Seoul and towards the mountains that frame the metropolitan area.
Within the observatory complex, different levels offer varied vantage points, including indoor viewing halls, areas with glass floors that reveal the drop towards the streets far below, and terraces where the city’s lights and river bridges form a broad panorama.SEOUL SKY observatory The ascent from the base to these upper levels is made by a high-speed elevator system housed within the tower’s core, turning the vertical journey itself into a distinct part of a visit.
Structure, design and the skyline
Lotte World Tower was completed in December 2016 after a multi-year construction process and opened to the public in April 2017, joining the ranks of the world’s tallest buildings certified by international tall-building organisations.Completed December 2016 The building’s structural system, designed to withstand wind loads and seismic forces, supports the slender form and the mix of uses that occupy more than 120 occupied floors above ground.
The tower’s exterior cladding and lighting schemes emphasise its vertical lines, making the building a prominent feature in views from many parts of Seoul and from aircraft approaching the city. As a single project combining offices, residences, hotel accommodation, retail areas and a large observatory near the summit, it serves as a concentrated example of high-density development within a relatively compact footprint.mixed-use building
