Digital Media City Landmark Tower is located in the north of Han River on the west bank of Seoul Digital Media City Landmark tower rises as a gateway to the city. Design of the tower is shaped through the curved forms of soft and smooth transition between the main facade of the east-west and north-south. Mega-column expressions reinforce the perimeter of the mass change and provide a natural break for the series of solar louvers. On the east and west facades both horizontal and vertical patterns shield from the sun’s rays at the beginning and end of the day, while in the south horizontal shades the face shield of the high afternoon sun. Along with a towering crown which collect and channel the light and help power the building through the architectural expression of a wind turbine towers strengthen the core sustainability strategy of this design.
