Huaian, a historical and cultural city in China, was once the capital of canal transport. The city pattern is dumbbell-shaped. The main city in Northwest and the ancient city in Southeast are connected by Xiangyu Avenue. In 2008, the government decided to build a new eco-business district in the middle of the“ dumbbell”. In the same year, the “Four Pavilions” took the lead in locating on the northeast side of Xiangyu Avenue in the new district, along the millennium Li-canal , with a land area of 5.44ha and a total building area of 86500㎡. The main functions are urban plan exhibition halls, libraries, cultural galleries, art galleries and their supporting rooms. The site is a rectangle parallel to Xiangyu Avenue, 350 meters long and 160 meters wide. It is divided into two relatively independent parts: the northwest Urban Museum land and the southeast Cultural Museum land. The plan calls for a unified retreat of the four pavilions to form a 60-metre display of the main features of Xiangyu Avenue. As the first large sized project there, how can we lead the style and features of the new district, echo the context of the old city and form local affinity?
设计难点 | Difficulties
The integration of generality and individuality: As a multi-pavillions joint building, it should not only highlight the overall atmospheric simplicity, but also take into account the diverse needs of individuals.
The integration of history and modernity: it is necessary to conform to the new town fashion, inherit the ancient city context, and echo traditional architecture with modern architectural language.
The integration of practicality and symbolism: giving consideration to functions and images, responding to different functions of libraries by means of multiple symbols, and increasing local affinity.
The integration of architecture and environment: not only to form landmarks, but also to set aside landscape green veins and visual corridors for adjacent blank plots.
空间形态 | Morphological manipulation
To combine real images with virtual ones: The functions of each hall have different requirements for natural lighting and ventilation, such as the foyer, art salon, creative room, reading room, concert hall, exhibition hall, etc. The facade is corresponding to glass curtain wall, stone blinds, large-area solid wall and so on, in order to seek the combination of virtual and reality, and different from each other.

Context inheritance: With modern technologies such as large span, large cantilever, wide and narrow staggered joints and dry-hanging honeycomb stone, it echoes the quadrangular courtyard on the sloping roof, eaves gray space, hook joints of clear water wall, eaves rafter closure and so on which are existed in the historic buildings of the old city.

Local symbol：Huaian is the capital of canal transport. The inspiration of the overall shape of the “Four Pavilions” comes from Huaian’s Most Characteristic Caofang. The inspiration of the Urban Plan Museum comes from the heavy ancient Gate Tower. The shape of the concert hall is composed of 12 “petals”, which symbolizes the blooming of Huaian’s roses.

Landscape infiltration: By lowering the central part of the building, the pavilions are separated into courtyards, supplemented by various grey spaces, to achieve indoor and outdoor integration, and to infiltrate into the open space of the surrounding cities, leaving a landscape green vein and a vision corridor for the adjacent areas to be developed.

Cantilever outdoor space: In order to obtain more outdoor landscape space and increase the infiltration of indoor and outdoor space, the building combines with outward inclined wall, layers of balconies, roof gardens and gray space are set up, 80 meters long reinforced concrete structure, cantilever up to 12 meters.

Organic integration of equipment and devices: Concert hall for example, the plane is nearly rectangular, about 10 meters high, large-scale heating and ventilation equipment is needed on both sides, so the plane is integrated into a circle, combined with equipment ventilation, part of the outer wall is covered with louvers, and then generated 12 inclined walls, as if blooming rose petals.

The Fifth Facade: Using those parts of inclined roof higher than flat roof, the roof shaft and machine room are skillfully designed, and then the roof equipment and pipelines are shielded by light shading frame to ensure the beauty of the fifth facade.

细部设计 | Detail design
Wide and narrow staggered seams: Exhibition hall, concert hall, library and other external walls are mainly solid walls. Inspired by the wide and narrow joints of the clear-water brick wall of Zhou Enlai’s former residence in Chuzhou, the stone is 1350 to 1800 in length, dry-hanged with 150/300/600 three widths and staggered by one third. In order to ensure the simplicity of large solid walls, especially the safety of extroverted walls, dry-hanging honeycomb stones with light self-weight and large block surface are used.

Stone louvers: Reading rooms and studios adopt the combination of “stone louvers” and glass curtain wall, taking into account the functions, vision, image and energy saving. The honeycomb stone slab is spliced into 300 wide *450 deep through-long column members, and then arranged transversely according to 1050 center distance, with the width of the window about 750.

Under the eaves: The bottom of the “stone louver” is vertically closed to the glass curtain wall, just like the effect of the bottom of the eaves of the traditional sloping building, which makes the space under the eaves of this modern cultural building have some inheritance of Context.

结语 | Epilogue
From the design to the completion of the project, we hope that the “Four Pavilions” will be like a “cultural carrier” sailing into the cultural life of millions of households and leading a new future of Huaian.
