Appreciation towards CAB Architectes for providing the following description:


When we discovered the immense sky and the plateau devoid of physical constraints we sought to capture the landscape by a simple form and by an abstract architectural language.

▼建筑外观,exterior view

▼简洁、抽象、轻盈的体量,a simple form with an abstract architectural language

▼立面近景,a close view of the facade

▼建筑框架由一系列H型钢梁交织而成,the project is defined by a steel exoskeleton made of H-beams


The proximity of the site to the edge of the woodland led us intuitively to the primary material as it seemed necessary in this country-side site to place the building lightly on the ground. To achieve this we chose to define the project by a steel exoskeleton.

▼建筑呈现出开放、友好和具有城市特征的氛围, the building is both open, welcoming and urban

▼室外公共空间,outdoor public area

▼充满自然气息的回廊和庭院,the corridor and courtyard are full of natural breath


Inscribed within a 80 x 80 metre square, the building is both open, welcoming and urban, yet borrows from the language of a cloister to create an intimacy of an interior landscape. The grid of 3.05m x 2.10m sections made of 24×24 cm H-Beams weave together the entire project and outline the architecture.

▼设计借鉴了修道院回廊的建筑语汇,打造出亲切宜人的内部景观,the design borrows from the language of a cloister to create an intimacy of an interior landscape

▼室外露台,outdoor terrace


▼教学楼内部,internal space

▼图书室及自习空间,library and studying area

▼钢结构在室内清晰可见,inside the building the structure remains visible

▼阶梯教室,lecture hall


▼洗手间,wash room

▼室内局部,detail of the interior




With no intermediate support points, steel structure beams with a span of 15 metres link one facade to the other. They are connected to the exostructure by steel connectors of 15x15cm, reduced in size to limit their impact. The structural grid is mounted like a giant Meccano set. Inside the building the structure remains visible, recalling, if needed, that the expression of the construction sets both the rule and the meaning.
