Sunflower Co., Ltd is located in the central area of Zhongguancun. The company consists two parts: capital investment and network. Thus, for the designing it is divided into three main areas. The middle area includes front desk, conference room, tea room, VIP room, etc. The southern area is the working area for the investment company, and the northern area is the working area for the network company. We use the straight line for the aisle of the whole floor and make the space transparent. We also ensure the natural lighting via the windows. Cork board is used for the walls and pillars. The white glass facilitates the communication between the employees. By using the plant boxes and the placing of the boxed, the indoor environment becomes more of the nature. We use the colors--- golden yellow, blue and green as the main color tones, which bring the theme concept to every employee and the customer here.
