Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest point of the building, irrespective of material or function of the highest element (i.e., including antennae, flagpoles, signage and other functional-technical equipment).
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the architectural top of the building, including spires, but not including antennae, signage, flag poles or other functional-technical equipment. This measurement is the most widely utilized and is employed to define the Council on Tall Buildings and Urban Habitat (CTBUH) rankings of the "World's Tallest Buildings."
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest occupied floor within the building.
The number of floors above ground should include the ground floor level and be the number of main floors above ground, including any significant mezzanine floors and major mechanical plant floors. Mechanical mezzanines should not be included if they have a significantly smaller floor area than the major floors below. Similarly, mechanical penthouses or plant rooms protruding above the general roof area should not be counted. Note: CTBUH floor counts may differ from published accounts, as it is common in some regions of the world for certain floor levels not to be included (e.g., the level 4, 14, 24, etc. in Hong Kong).
The number of floors below ground should include all major floors located below the ground floor level.

The International Finance Centre, located at the center of Yeouido Island, serves as a major pedestrian link between the subway station, riverside, and Yeouido Plaza Park. The inspiration for the IFC Seoul came from Asian landscape drawings that often depict very steep, jagged mountains. The four vertical towers were designed to resemble monumental crystalline outcroppings, chiseled to create prismatic forms that accentuate the interplay of light and shadow on the glass façade.
Expansive floor-to-ceiling glass and nearly 10-foot ceilings immerse the office spaces in natural light and provide magnificent, uninterrupted views across Yeouido Park and the Han River to the mountains beyond. Bay depths of more than 42 feet (12.8 meters) from elevator core to the perimeter wall ensure efficient use of space. To improve the experience on subterranean levels, the design includes large skylights to admit natural light, articulating the glass entry pavilions leading into the IFC Seoul Mall.
