Sejong Media Plaza is a multipurpose building. The design was developed based on 'Media Office Cube' and 'Commercial Community Cube' themes. A pleasant space plan was established by separating functions and planning the traffic. By placing the building core to the northwest and the workspace to the south, we tried to provide an optimal work environment. In addition, the lower part of the building was made accessible from anywhere along the street to contribute to revitalizing the streets. The biggest feature of the design is that we planned the Sky Lobby and Biz Center that can be connected to the rooftop landscaping by placing the office lobby above the shopping mall on the lower level. Also, on the fourth floor, we placed a multipurpose hall that can accommodate about 300 people to hold events such as performances and conventions. In addition, we reduced the window area to reduce the cooling load during summer and formed an elevation that gave depth to the skylight. As for the shape of the elevation, we created a solid image through simple forms and expressed the depth of the volume of the elevation to suit the building of a press company.
