In designing office space in current era, human beings, that is office users seem to be taken into account more than any time in history. Office space is becoming not just administrative space, but a place of communications and creative decoration. It is not a place for the system of just coordinating production operations and work, but a place for a variety of dynamic job performances based on space users’ initiative actions. The focus of office space design is more on providing human beings with emotional support to adopt and tackle changes better and encourage them to work more creatively rather than on functional aspect. Conventional way of office design was often repetitive work. However, now it is to be transformed into more creative space. This project requires creative inspirations and a diverse and high level of work capacity. It also designs the space as a living place for people to think, rest and work with multiple functions. Especially, in planning lobby area natural and environment-friendly materials will be used instead of artificial materials to accommodate rest area, event area and information communicating area. Conference area is also designed to be flexible to meet changing needs of space use instead of restricted in conventional one function of its use.
