A new entrant is set to grace the list of the world's top 10 tallest structures this year. Situated in Seoul and presently under construction, the Lotte World Tower, standing at an impressive 555 meters, aims to set new standards for skyscraper heights in South Korea. If the architectural visualization of the project is an accurate representation, Kohn Pedersen Fox's stylish and refined 'bullet-like' design will soon be a part of Seoul's skyline. As is the case with numerous modern multibillion dollar ventures, the inception of the Lotte World Tower was filled with controversy, requiring long years to become a reality.
As expected, the design team at Kohn Pedersen Fox went for a modern aesthetic, being inspired by a rich history of Korean artistry in ceramics, porcelain and calligraphy. The tower's tapering curvature is sleek and imposing - even egotistical; and is testament to a culture that holds perfection as one of its defining principles. At 123 stories, the building is set to bring together a retail, office and 7-star hotel program. The building's top ten floors have been set aside for extensive public use and entertainment facilities and will feature a roof-top café and an observation deck.
The curtain walling system shines amongst all of the design team's manoeuvres. Like two elongated shells, the building's skin separates ever so slightly from the tower's shoot extending way after the last floorplan. At its zenith, the now bisected crown is transformed into an apex of two seams that run alongside each other - paying tribute to the old centre of the city. The architectural edifice stands structurally sound thanks to a concrete core that is surrounded by 8 concrete super-columns all resting on a concrete mat that is tied back to the core with steel outrigger trusses. Lateral loading is taken into account by belt trusses that are placed at every point of major programmatic transition. The pinnacle melts into the primary elements of the steel frame and gains a much appreciated transparency.
The Lotte World Tower has ambitions to achieve LEED Gold Certification and echoes the Lotte Group's tenet for environmental sustainability. Several sustainable design strategies were employed including photo-voltaic panels, wind turbines, external sun-shading devices and rainwater harvesting systems. It is easy for super-skyscrapers to be imposing to their immediate context; but Kohn Pedersen Fox has managed to come up with a design that is subtle enough to fit in a melee of an architecturally busy landscape. Inasmuch as the tower might not be the most stellar in the list of the world's tallest buildings, it sets an important local precedent for South Korea to follow.
