進景觀新的兩面性 | Contribute to a new polarity in landscape
項目場地位於法國濱海藝術中心（Esplanade de France）聖埃蒂安車站（St-Etienne station）對面，是聖埃蒂安地形較低的區域。作為ZAC Châteaucreux的中心區域，該場地連接了附近社區與城市的橫向軸線，並引導著通向市中心的線路。項目獨特的地理位置結合其規模與象徵意義，使其在城市建設中擁有了特殊的地位。

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.

該項目遵循了當代城市建設理念，即在城市中構建有節奏的多用途空間，以此減少線性空間，提升空間的可發展性及可變化性。項目的目標是將社區的大型商業體嵌入到複雜的城市動態環境中，成為有活力的大型城市不可或缺的一部分。因此，該項目一層採用了開放性佈局，旨在提升空間的連續性與融入性，使其兼顧對比與統一，並在山丘與平原及上下城鎮之間建立起聯繫。
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.

拓撲結構| Topographic composition
經過對聖埃蒂安土地用途的初步研究，設計師團隊最初推演的建築體塊由場地與城市框架之間的關係確定。隨後，體塊變形為三個聚集體，一個複雜的多面體及兩條軸線。體塊遵循特殊的規則變化，從而形成新的地形。最終，設計團隊創造出了便於遊覽且生機勃勃的開放式空間，空間的組織充分滿足項目的多功能需求，因順應城市發展而日益充滿活力。

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.

項目著重考慮了空間密度，質量，空隙及體量之間的關係。設計團隊最初根據嚴格的限制確立了精確的體塊，從而獲得高密度的公共空間，避免空間的浪費。根據建築體塊的推演，街區的中心形成了第五個橫向立面，創建了開放性走廊，使建築獲得能夠欣賞到周邊景色的視野。

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.
