Les Préalpes旅舍位于瑞士Gruyère山谷著名疗养院le Rosaire不远处。这里最开始是寄宿处和乳品厂，后来被改造成旅舍，变成社交聚会的场所。因而该建筑具有重要的社会意义，其位置、朝向、比例和设计也在村庄中脱颖而出：退后于受到树木保护的道路；以玻璃条窗、木板和阳台面向阿尔卑斯山。

The former guesthouse «  Les Préalpes » is situated in a short distance from the famous sanatorium le Rosaire, in the Gruyère valley in Switzerland. It was originally a boarding house and a dairy factory. It became a place of social gathering when it was transformed into a guesthouse. Thus its social importance, the building with its location, orientation, proportions and design stands out within the village fabric : set back from the road protected nowadays with trees, facing the alps with crafted ribbons of glazed openings, wooden paneling and balconies.

随着时间推移，旅舍发生了翻天覆地的变化。建筑两侧进行了不同扩建，失去了原有平面和立面的对称布局，取而代之的是一间大餐厅。在这里关闭数年后，人们在2018年对这里的翻修事宜进行了讨论；2019至2021年，旅舍被改建为3套公寓和1个保健中心。改造后，外墙内的公共和私人空间保持了建筑物的原始特点。

Along the years, the guesthouse was transformed. Different extensions were added on both sides of the original building losing the initial symmetrical layout in plan and elevation in favor of a large dining hall. After several years being closed, the discussions about its renovation begun in 2018. The guesthouse was transformed from 2019 to 2021 into 3 apartments and a health-care center. The public and private programs within the realms of the walls seek to maintain the building’s initial social identity.

该项目通过大量干预措施来恢复建筑的整体感和完整性，以这里在1925的规则变化和精致细节为基础改造窗洞口、保护层和大型标识。为了扩大面积，内部楼梯被移至建筑后侧，即使如此，室内依然保持原始布局：一条中央走廊穿过两侧房间，走廊尽头是主要的生活空间，面朝阿尔卑斯山脉景色。阁楼上新设置了天窗，起到外部对称和内部采光的作用。古铜色屋顶上的太阳能电池板经过修整，为建筑提供可再生能源。在拆除先前墙体并使结构承重后，保温层符合了实际标准。此外，前入口和主立面上的石阶被保留下来，作为过去留下的历史物件。
