JCM住宅丨瑞士丨Ralph Germann architectes SA

原建筑为一座谷仓，上层用于储存干草，下层则在当时被农夫作为临时居所使用。原有屋顶坡度较陡，使积雪能够滑落，不会在屋面停留过久。深挑的檐口保护了立面免受风雨侵蚀。原有的三角形开口用于谷仓通风，以利于干草的保存；在改造过程中，这些开口被保留，并加装了玻璃。

The original building was a barn, with hay stored on the upper floor and the ground floor used as temporary accommodation by the farmer at the time. The rather steep pitch of the original roof allowed snow to slide off and not remain on the roof for too long. The very deep eaves protected the façade from the elements. The original triangular openings provided ventilation for the barn to preserve the hay; during the renovation they were retained and fitted with glazing.

主要改造要求由州级建筑管理部门提出，即在品质层面上必须严格尊重既有建筑及其周边环境的特性，因为该物业位于农业区范围内。

The principal requirements were set by the cantonal building authorities, namely that, in qualitative terms, the works had to strictly respect the identity of the existing building and its surroundings, as the property is located within an agricultural zone.

原谷仓的所有构件均被保留，包括屋顶——其被拆除后进行保温与防水处理，随后使用1913年铺设的原有瓦片重新组装。原有开口，如门与窗，保持了原有比例，并加装玻璃。上层沿立面设置了一处大型开口以引入自然光，同时整体采用水平木板覆面，以维持建筑的一致性。

All elements of the former barn were preserved, including the roof, which was dismantled, insulated and waterproofed, then reassembled using the tiles laid in 1913. The original openings, such as the doors and windows, retained their original proportions and were fitted with glass. On the upper floor, a large opening was created along the façade to bring in natural light, and the whole was clad with horizontal boarding to maintain architectural coherence.

改造的核心理念在于尽可能保留原始体量，使居住者能够体验置身于一座19世纪谷仓之中的空间感受。为此，在原有体量内部嵌入了一个由玻璃与木材构成的“大盒子”，用于容纳居住空间。

The main idea behind the renovation was to retain as much of the raw volume as possible, allowing occupants to experience living within a nineteenth-century barn. To achieve this, a large “box” of glass and timber was inserted within the volume to accommodate the living spaces.

在生态策略方面，项目再利用了谷仓内部的全部木材，用于制作厨房及底层的门。外立面与室内墙面均采用保温石灰抹灰。上层在天花与墙板之间填充喷吹式矿物棉保温材料。供暖与热水系统由空气源-水源热泵及辐射式钢制壁炉提供。

Among the various ecological considerations was the reuse of all the timber from inside the barn to craft the kitchen and the doors on the lower floor. Insulating lime render was used on both the external and internal façades. The upper floor was insulated between the ceiling and wall boards using blown mineral wool insulation. Heating and hot water are provided by an air-to-water heat pump and a radiant steel fireplace.
