促进景观新的两面性 | Contribute to a new polarity in landscape

项目场地位于法国滨海艺术中心(Esplanade de France)圣埃蒂安车站(St-Etienne station)对面,是圣埃蒂安地形较低的区域。作为ZAC Châteaucreux的中心区域,该场地连接了附近社区与城市的横向轴线,并引导着通向市中心的线路。项目独特的地理位置结合其规模与象征意义,使其在城市建设中拥有了特殊的地位。

Located across from the St-Etienne station on the Esplanade de France, the influence of the intervention at the heart of the ZAC Châteaucreux is a link between neighborhoods and horizon lines, a low point in the topography of St-Etienne in front of a preferred route to the city center. Combined with the scale of the project and the symbolic value of the program, this unique location gives the project a special status in the construction of the city.

to the contemporary idea of the construction of the city that leads to the creation of rhythms, of multipurpose spaces contributing to the realization of a less linear environment, able to evolve and mutate. The goal is to embed the large commercial component of the neighborhood in a more complex urban dynamic, made of interlocking assemblies essential to any large and vibrant city. Thus, the project offers an open floor plan, initiating continuity and affiliations, creating links between polarity and panoramas, hills and plains, lower and upper town.

In a preliminary study of the uses of land in St-Etienne, we began to articulate a sculpted volume, defined by its relationship to a city structured by the frames and cut outs on the horizon. The initial volume deforms, breaks into three compact masses, a multiplicity of plans and volumes and two mineral axes. The volume deteriorates in a specific manner leading to the establishment of a new topography. It is therefore a very open plan, traversable and animated, a space organized by the characteristics of the multi-purpose program, able to create discourse with the city to better develop and animate it.

Considerations of density, mass, voids and solids were central in the development of the project. The project is first extruded to form an exact podium to ensure alignment and management of tight limits in order to densify and animate public spaces without residual anecdote. The heart of the block forms a fifth unifying and transversable facade, which is fully engaged in the work of modeling the volume, creates an open promenade and provides a view of the surrounding landscape.
