烟台龙湖葡醍海岸西岸公园公共卫生间位于海边咖啡厅与儿童游乐区域之间，需要满足较大的公共使用需求。作为公园中必要的公共服务设施，设计尝试将这一功能性建筑转化为景观系统中的一部分，通过尺度、布局和材料与周围环境建立联系。

Located between the seaside café and the children’s playground in West Park at Longfor Puti Coast in Yantai, China, the West Park Public Restroom serves as a public facility within the park. Rather than functioning as an isolated utility building, the project seeks to integrate this necessary facility into the landscape system through its scale, spatial organization, and material choices.

为了融入周边树林并减少单一大体量建筑对周围环境的影响，设计在满足核心服务需求的前提下，采用分体式布局，将男卫生间、女卫生间和第三卫生间分别组织为三个独立体量。三个建筑单元错动布置于树林之间，并与室外儿童洗手洗脚池共同形成连续的空间体验。游客沿蜿蜒的小径穿过树木进入其中，拉长的进入路径与建筑之间形成的开放空间成为停留、等候的场所。

To integrate the building into the surrounding woodland while accommodating essential programmatic requirements, the design avoids a dominant building mass by organizing the restroom functions into three independent volumes—the men’s restroom, women’s restroom, and accessible restroom. Positioned among the trees with slight shifts in orientation, these volumes, together with an outdoor washing area for children, create a continuous sequence of spaces. Visitors approach the facility along a winding path through the trees, where the extended entrance sequence and the open spaces between the volumes provide areas for waiting and pause.

海洋生物元素是该区域空间主题的重要组成部分。项目从海洋形态中提取三种空间操作——旋转、叠合与开启，并将其转化为建筑语言。海螺的旋转特征为平面空间提供了组织方式：每个卫生间单体均由1–2片倾斜的现浇混凝土曲面墙体围合形成，墙体卷合后自然形成入口空间。

Marine-inspired elements are an important part of the design language of the park. The project translates three spatial operations derived from marine forms—rotation, layering, and opening—into architectural strategies.The spiral movement of a conch shell provides the organizational principle for the plan. Each restroom unit is formed by one or two inclined cast-in-place concrete curved walls, which wrap around the interior space. The natural opening created by the curved walls forms the entrance.

为回应树林环境中不断变化的光影关系并进一步消减建筑的体量，立面采用40厘米宽的木纹板单元构成类似鳞片的表皮。木纹板通过金属龙骨固定于混凝土墙体外侧约20厘米处，形成独立于主体墙面的外层表皮。每块板片均相对于墙体产生约2度的水平旋转，使相邻板片之间形成层层交叠的关系。同时，每隔一个板片在垂直方向进一步旋转约2度，在统一排列逻辑下产生细微错动。

To respond to the changing light and shadow conditions within the woodland and further reduce the perceived mass of each volume, each facade is articulated by a wood-grain panel system composed of repeated 40-centimeter-wide units, forming a scale-like outer layer. The panels are fixed to the exterior of the concrete walls with metal frames, approximately 20 centimeters away from the main structure, creating an independent secondary skin. Each panel is slightly rotated horizontally by approximately 2 degrees relative to the wall surface, creating overlapping layers between adjacent panels. In addition, every other panel is further rotated vertically by approximately 2 degrees, introducing subtle variations within a consistent ordering system.

人与环境的互动是设计的重点，考虑到公园环境中的使用场景，卫生间被设计为不完全封闭的空间。屋顶与墙体之间保留缝隙，形成类似贝壳微微开启的状态。自然风和外部景观由此进入室内，建筑得以时刻与周围环境保持联系。室内空间延续整体、自然的材料策略。浅色墙面涂料与水磨石地面形成统一背景，卫生间隔断及洗手台等功能构件采用金属材质便于清洁打理，木质边框镜面设置于洗手区域，为空间增加温暖的细部尺度。

Considering the relationship between the restroom and its natural surroundings, the building is designed as a partially enclosed space rather than a completely sealed structure. A continuous gap is maintained between the roof and the walls, evoking the opening of a shell. Natural ventilation and views of the surrounding trees enter the interior through this opening, allowing the building to remain connected with its surroundings. The interior continues the overall material strategy through a restrained and natural material palette. Light-colored wall finishes and terrazzo flooring create a unified backdrop, while metal partitions and washbasins provide durable functional surfaces. Wooden-framed mirrors are placed in the washing areas, adding warmth through smaller-scale details.
