回收五个建筑和一个花园。El Til-ler – 菩提树学校被小心翼翼地插入一个大型的、成熟的、废弃的私人花园中，位于巴塞罗那附近的贝拉特拉花园郊区。该建筑群沿着现有的主要通道衔接，成为一个 “兰布拉”–地中海地区对高街的称呼–在一个向景观开放的广场结束。

Recycling five buildings and a garden. The El Til•ler – Linden Tree- School is carefully inserted into a large, mature and abandoned private garden, in the garden suburb of Bellaterra, close to Barcelona. The complex is articulated along the existing main access path, which becomes a “rambla” -the Mediterranean name for high street- that ends at a square which opens to the landscape.

组成学校的六座建筑中，有五座是现有的木制和钢制的模块亭子，它们来自学校以前占用的另外两个场地。这些建筑被拆卸、运输，并在新址上精确地重新配置，以适应地形、现有植被、阳光照射和景观。这里介绍的第六座建筑，是幼儿园和公共空间的所在地。

Five of the six buildings that make up the school are existing modular pavilions of wood and steel which come from two other sites previously occupied by the school. These buildings are disassembled, transported and precisely reconfigured at the new site, adapting to the topography, existing vegetation, sun exposure and views. The sixth building, which is presented here, houses the kindergarten and the common spaces.

序列、地平线、光线。城市设计是教学法的一种表达。学校提出了一个适应地中海气候的华德福-斯坦纳教学法的现代空间表达。因此，没有内部走廊，进入教室的通道遵循一个渐进的外部空间顺序：兰布拉-庭院-门廊-接待大厅-教室。

Sequences, horizons, light. Urban design as an expression of pedagogy. The school proposes a contemporary spatial expression of the Waldorf-Steiner pedagogy adapted to a Mediterranean climate. Thus, there are no interior corridors, and access to the classroom follows a gradual exterior spatial sequence: rambla – courtyard – porch – receiving hall – classroom.

地平线–视野–随着孩子的成长而扩大，而教室在地形上的旋转使它们在强度和颜色上都有不同的光质。顺序、地平线和光线使每个教室个性化，强调并伴随着成长和学习的经验。

The horizons -the views- expand as the child grows, and the rotation of the classrooms on the topography gives them varying light qualities, both in intensity and color. Sequences, horizons and light personalize each classroom, emphasizing and accompanying the experience of growing up and learning.

凹槽和框架。建筑作为教育学的一种表达。这座容纳幼儿园和公共空间的新建筑将平面图从柱子中解放出来，并将柱子集中在外墙，形成厚厚的扶壁，使幼儿园的教室有可能被放置在一个必然没有柱子的多功能厅之上。墙垛之间的空间成为凹槽，根据每个空间的功能和教学需要来确定其形状。

Alcoves and frames. Architecture as an expression of pedagogy. The new building, which houses the kindergarten and common spaces, frees the plan from columns and concentrates them at the facades in the shape of thick buttresses, making it possible to place the kindergarten classrooms on top of a necessarily column-free multi-purpose hall. The spaces between the buttresses become alcoves, which are shaped according to the functional and pedagogical needs of each space.

在外面，这些凹槽被包含在框架内，使外墙有序，并在视觉上缩小了建筑的尺寸，使其更接近儿童。华德福教学法中最独特的空间元素–“季节性桌子 “组织了新的幼儿园教室。这个小的 “祭坛 “是解释自然周期的地方，它被集中放置在一个凹槽里，提供特定的自然光–侧向、反射和漫射。

On the outside, the alcoves are contained within frames which order the facade and visually reduce the size of the building, bringing it closer to that of children. The “seasonal table”, the most unique spatial element of the Waldorf pedagogy, organizes the new kindergarten classrooms. This small “altar”, where the cycles of nature are explained, is placed focally, within an alcove that provides a specific natural light -lateral, reflected and diffuse.

被动的气候舒适和预算优化。木纤维板的隔热性能和巨大的混凝土结构的惯性几乎完全消除了冬季的供暖需求。在一年的其他时间里，由于通风的外墙、外部的铝制商店百叶窗和自然交叉通风，实现了舒适。

Passive climatic comfort and budget optimization. The thermal insulation of wood-fiber panels and the inertia of the massive concrete structure almost completely eliminates the need for heating in winter. Comfort during the rest of the year is achieved thanks to the ventilated facades, the external aluminium store blinds and natural cross ventilation.

体积的紧凑性、混凝土结构和外墙的半预制化–完全是木制的–以及建筑材料的暴露，使得在非常紧凑的预算内为家长和教师合作社建造这所学校成为可能，这比公立学校的通常预算低。外墙从一个平面演变为一个居住的空间，教室变成了房子，学校变成了一个沿着兰布拉大道的小村庄。

The volumetric compactness, the semi-prefabrication of both the concrete structure and the facades -entirely wooden- and the exposure of the construction materials without claddings have made it possible to erect this school building for a cooperative of parents and teachers within a very tight budget, lower than the usual in the public school sector. The facade evolves from a flat surface into an inhabited space, the classroom turns into a house and the school becomes a small village along a rambla.
