施拉赫贝尔海姆新市政厅丨法国

施拉赫贝尔海姆新市政厅坐落于一座阿尔萨斯小村庄之中，其设计以水平延展与通透性为核心，力图融入这片壮丽的林地环境。木结构外部规则而清晰的框架强化了建筑的公共属性，同时确保了一种超越流行的、恒久的美学表达。松焦油形成的深色、丝绒般的防护涂层，以及比例精致而优雅的木柱尺度，既呼应了村庄传统的木构半木结构，也回应了场地中的树木意象。耐候钢拉伸网状立面赋予建筑立面近似织物般的质感，其色调则呼应了当地历史村落中大量存在的石材（孚日砂岩）的自然色泽。整体建筑既当代又扎根于地域，既严谨又温和，仿佛自始便存在于此。

The new town hall of Scharrachbergheim, a small alsatian village, seeks horizontality and transparency to integrate into this magnificent wooded site. The external regular framework of the wooden structure affirms the public dimension of the building, while ensuring a timeless aesthetic, out of fashion. The dark and velvety tint of the protective pine tar and the refined and elegant sizing of the wooden columns echo both the village’s colombages and the site’s trees. The corten steel expanded mesh cladding gives an almost woven appearance to the facade and the hue recalls the tones of local stone (Vosges sandstone) very present in the historic village. The ensemble is contemporary but rooted, rigorous but gentle. As if it had always been there.

建筑中央，一处拔地而起的体量为接待大厅提供了宽敞而充盈的室内空间，这里是新市政厅的核心。同时，这一体量更承担着面向整个村庄的标志性角色，象征着未来市政厅应当构建的全新公共中心性。体量顶部设置了一枚铜制风向标，融合了村庄的两枚纹章，在延续传统建筑语言的同时，也重新唤起人们对符号与象征所蕴含的、近乎童真的愉悦与惊奇。这一中央体量同时在建筑的自然过度通风中起着关键作用，为夏季热舒适性作出积极贡献。建筑采用生物基保温材料，具备显著的热相位延迟性能，并与混凝土楼板的热惰性相结合，使建筑在四季中都能保持舒适，仅需极少的供暖能耗（达到被动房标准），且无需任何主动制冷系统。室内隔墙采用夯土砖（adobe）砌筑，部分裸露，部分覆以白色土质饰面。这些砖块由距施工现场约20公里的兰特（Lanter）手工砖厂制作，使用黄土与稻草砂浆砌筑，工艺与阿尔萨斯传统的泥草填充建造技法（torchis）一脉相承。

At the center of the building, a built emergence offers a generous interior volume to the reception hall, the heart of this new Town Hall. But it acts above all as a village-wide signal for this new centrality that the future Town Hall must constitute. A copper weathervane incorporating the 2 blazons of the village is installed at the top and completes this connection to traditional architecture while reconnecting with the almost childish pleasure and wonder of signs and symbols. This emergence is also crucial for natural over-ventilation of the building, actively contributing to summer comfort. The insulation is bio-based and provide a strong thermal phase shift, coupled with the inertia of the concrete slab, for a comfortable building in all seasons, requiring very little heating (Passivhaus level) and zero active cooling. The interior partitions are made of raw-earth bricks (adobe), left exposed or covered with a white earth finishing. These bricks, made by the artisanal brickyard Lanter (20km from the construction site) are masonry with a loess and straw mortar, like the torchis technique of the Alsatian constructive tradition.

建筑整体结构完全由木材构成，包括主体结构、木框架墙体、窗框以及室内饰面。主要梁跨越建筑的整个宽度，使空间在无中间支撑结构的情况下获得高度的灵活性，便于未来功能调整与多样化使用，宛如一座木构皇冠大厅。本地木构架在整个建筑中保持外露状态。在议会与婚礼大厅内，结构通过优雅的形变塑造出一座木质拱顶，为这一象征性空间赋予庄重与充盈的仪式感。弧形梁由实木直接切割成型，延续了祖传的建造技艺，无需胶合、弯折或其他复杂工艺。数字化技术的介入，使梁的截面形式得以多样化，从而在双向上形成变化的结构惯性拱顶。

The entire structure is made of wood (framework, wooden frame walls, windows frames and interior finishings). The main beams span the entire width of the building allowing freedom of development and subsequent uses without intermediate structure. A kind of wooden Crown Hall ! The local wood framework is left exposed throughout the building. In the the council and weddings hall, the structure is elegantly deformed to create a wooden vault giving fullness and solemnity to this symbolic space. The curved beam are made of solid wood cut, thus resuming an ancestral savoir-faire, without needing any gluing, bending or other complex techniques. The digitization allows a variety of profiles creating a variable inertia vault in both directions.

议会与婚礼大厅通过两扇大型推拉门向室外敞开。这种室内外的连续性赋予空间多样化的使用方式，并将建筑与这一全新的公共交流与聚会场所直接连接，使其真正服务于所有人的日常生活。

The council and weddings hall opens generously towards the outside through two large sliding frames. This interior/exterior continuity allows a varied use, and a direct connection with this new space of meeting and conviviality, for the use of all.
