Appreciation towards Dominique Coulon & associés for providing the following description:
项目基地位于伊斯贝格小镇和城际公园的交界处，因此设计团队需要从建筑体量、建筑在基地上的位置以及内部空间布局等方面来强调这一战略性的地理位置。
The site offers an interface between the town and an inter-municipal park. The project extrapolates this situation in terms of volume, positioning on the plot of land, and internal organisation.

在最终的方案中，项目相对于靠近公园一侧的基地边界后退，预留出一个宽敞的庭院，而另一侧则与小镇的街道平齐。建筑体量被包裹在当地生产的不锈钢表皮之下，缎面、镜面和哑光等三种不同质感的表皮在阳光下营造出一种极具动感的视觉效果。更为重要的是，随着日光的变化，各个建筑体量会依次借助光反射将自身完全融入灰色的天空中，制造出一种“暂时消失”的错觉。

The project creates a broad courtyard in front of the park on one side and an alignment with the town on the other. Its volumes slide over each other; they are covered with a locally produced stainless steel skin, in three different finishes – satin, mirror and matte – creating a kinetic effect reflecting the sunlight. This covering allows the building by turns to disappear into the grey of the sky and to reflect light intensely.

外表皮的丰富性和复杂性已经足以吸引人们的眼球，与此同时通透的入口空间也进一步邀请人们入内一探究竟。
The eye is drawn by the apparent complexity of the chaos, while broad transparent areas serve as catalysts directing visitors towards the entrances to the building.

建筑内部的空间组织十分明确。公园与小镇之间轴线贯穿建筑，在东南和西北两侧创造出两个入口。整个室内的功能区都由这条轴线来界定：剧院位于轴线的一侧，图书馆则位于另一侧。可以说，这条轴线既是空间的分隔线，也是空间的交汇处。动态的建筑体量和对比鲜明的光环境赋予了这两个功能区极强的可识别性。

The internal organisation of the building is clear. One axis between the park and the town crosses the project, thereby offering two entrances. The entire programme is grafted onto this axis, with the theatre on one side and the media library on the other. This axis serves as a federating interface. A dynamic arrangement of volumes and contrasting lights guide the visitor from this area towards either the media library or the theatre.

内部空间丰富多样。剧院的墙体由石锤修琢混凝土打造而成，从而改善了声学效果。而图书馆的各个区域在设计时都考虑到了人体工程学，在轮廓各异的空间中布置了一系列不同形式的阅读座椅。值得一提的是，故事区是由连续的褶皱限定的，从而让孩子们在一种具有安全感的环境下倾听世界。

The interior spaces are rich and varied. The theatre walls are in bush-hammered concrete, which improves the acoustic. The different areas in the media library have been designed with ergonomics in mind, and a number of different reading postures are proposed, using a platform with a richly varied profile. The storytelling area is formed by continuous folds which envelop the children in a confined space.

此外，得益于建筑凹凸折叠的造型，设计团队沿着外墙设置了一系列形状各异的室内观景平台，玻璃界面将室外的自然景观引入室内，在小镇与自然（城际公园）之间创造出一个过渡区。
▼景观面，visual framing
All along the proposed promenades, folding creates frames for a series of views out over the contrasting landscapes. This new arrangement is designed as an intermediary between the town and nature.
