The origins of renovations – from railway stations to museums. From a typological point of view, the spaces of the transport building and the exhibition building have a natural commonality. The high waiting room and platform space of the station are suitable for transformation into an exhibition space. The conversion of abandoned train stations to other functions has long been an international precedent. The most successful example is the Musée d’Orsay in Paris.
After the Huang (Bo) Sea Migratory Bird Habitat was officially inscribed on the “World Heritage List”, Yancheng urgently needed a window to show wetland culture to the outside world. The train station is next to the new wetland park. Transformed into a wetland museum, it will become a new reference point for showcasing the Yancheng wetland culture.
Renovation Strategies – Talk about the heritage of old and new buildings. The original railway station is spatially trussed and the partial floors are high and low, making it difficult to meet exhibition requirements. The upgraded design retained the lower concrete structure, removed the existing mesh, and added a steel roof to meet user needs. The mesh structure of the shell is reinforced with large-span trusses, and the shape of the roof can be realized without moving the original structure and foundation.
In terms of spatial relationship, the design continues the architectural scale and spatial relationship of the original railway station, clarifies the original architectural language and creates a new and modern architectural image. The Museum’s Public Hall uses the building’s existing structure to create an open and transparent urban public living room.
Technical implementation – The design system guarantees a high degree of completion. In order to maximize the permeability of the building facade, the curtain wall design uses a top and bottom steel frame load-bearing system. The precision steel profiles are only connected to the main structure from above and to the ground, and no other structural support point is needed in the middle. Exposed steel columns up to 24m high express the visual effect and structure of the curtain wall in a unified manner.
When modeling a roof, the corner of the original building is used as the starting point, and the tangent to the arc is used as the direction to create the contour line, and the rhythmic and uniform shape of the roof is formed using the gradient method. The silver-white line elements also reflect the intention of the Yancheng Wetlands to protect the feathers of the red-crowned crane.
During the circuit design phase, the structural engineer intervenes in advance to collaborate with the architect’s modeling project. From the original folded plate scheme to the mesh scheme, the hexagonal truss + contact truss scheme has finally been adopted. The disciplines work closely together to ensure consistency in roof form and structure.
During the reconstruction of the railway station building, the original station square and the waiting platform were also preserved and used. The square in front of the station and the entrance ramp have been transformed into a city square, while the waiting platform has been transformed into an outdoor exhibition area. At the same time, the original railroad tracks serve as the city’s axis, connecting the museum site with the new urban high-speed rail area, becoming an essential part of the entire urban design.
With the advent of the era of high-speed rail, the old stations in the city gradually lost their original transport functions. How to transform train stations to play a new role is a problem that many cities face. The example of Yancheng Railway Station is a new model for the renovation of existing buildings.
