A large scale Convention and Exhibition Center is not only a single building, but a system of complexity. Based on a rational function logic, a convention and exhibition center is organized by the order of the venues. It takes exhibition spaces as the core, matching up with entrance, conference, meeting, catering and etc. In the design of the Changsha International Convention and Exhibition Center, we made many efforts to balance a function logic and an image of local landscape: the building contour echoes the rhythm of local mountains and rivers, the organization of volumes maintains a clear and efficient order, and the architecture form presents a posture of openness and publicity. The gigantic Convention and Exhibition Center has achieved a harmony with Liuyanghe riverside urban landscape.
The design of the Changsha International Convention and Exhibition Center integrates logics of three aspects, including function organization, building structure and urban relationship. Complicated functions are organized into a scattered building groups, large span structure gives the space a lightweight form, and stretched roof respond to natural landscape, sculpturing a city image of elegant and harmonious.

The Changsha International Convention and Exhibition Center is positioned as the core building of the Changsha HSR New City. It is a signs for enhanced Changsha city image, improved urban functions, and a brand new business name card of the city.

It is planned to be built on the east bank of the Liuyang River in the Huangli district. The site is adjacent to the Liuyang River and close to the WuGuang High-speed Railway (HSR) New City. Located on the southern comprehensive development belt, the Convention and Exhibition Center has an advantageous location. In the future, this district will become a composite function area, integrating exhibition, conference, business, shopping, entertainment, reception centers and etc., and it will be the future city sub center.

Changsha is rich in hydrological resources, with the Xiangjiang River crosses the north and the south. The entire city is built along the water and thriving with water, with a reputation as “Shan Shui Zhou Cheng”. The Changsha International Convention and Exhibition Center is adjacent to the Liuyang River, a tributary of the Xiangjiang River. The unique geographical location nurtures the design inspiration. The design captures the contour of the Yuelu Mountain. The exhibition hall has an anti-arc skyline along the river to reflect the Xiaoxiang river image of Changsha. Stretching along Liuyang River, it conveys an aesthetic of traditional Chinese landscape painting. Meanwhile, the continuous curving roof along the river has strengthened the distant visions from the high-speed railway station.

The diversity and complexity of the convention and exhibition activities have given the Convention and Exhibition Center different functions and spaces. Exhibition halls are with a strong sense of strength and beauty due to its building structure demand for large span. All this is coordinated and unified.
The Convention and Exhibition Center has been divided into four parts: north-south entrance hall, exhibition halls, corridor, and outdoor exhibition area. Two promenades connects the four parcels in a serial sequence. The two entrance halls locate at the northern and southern ends. Exhibition halls are grouped in twosome, and in total of 6 groups. The exhibition hall roof contour is like the water wave curve. Each exhibition hall has its own subsidiary conferences, catering and other supporting facility space, in order to provide convenient services for the exhibitors. Courtyards enclosed by entrance hall, corridors and exhibition halls are designed into outdoor exhibition area. Simple and effective arrangements organized various functions, and ensured them efficient connections.
