Big Branzino 水上桑拿浴室 / Sandellsandberg

水上漂浮的独特体验与沉浸式自然观赏：Big Branzino 作为一座漂浮于水上的桑拿浴室，其核心价值在于提供一种独一无二的休闲体验。通过创新的结构设计，它将建筑主体置于斯德哥尔摩群岛的环绕之中，实现了人与自然环境的深度融合。无框玻璃设计和360度全景视野，模糊了室内外的界限，让使用者在享受桑拿的温暖时，能够沉浸式地欣赏周围的水域美景和星空夜色。这种将建筑功能性与极致景观体验完美结合的手法，是其作为现代休闲建筑的精髓所在。

精湛的工艺传承与材料的叙事性运用：该项目体现了对传统手工艺的尊重与现代设计的结合。由木工大师亲手打造的木结构，不仅是一次制造过程的展示，更是经验与技艺在细节中的体现，尤其体现在室内外家具和木饰面的处理上。材料的选择极具叙事性：内部的雪松营造温馨氛围，而外部粗糙的松木则呼应海岸线环境。此外，定制的黄铜元素（如舵和灯光开关）不仅提升了设计的精致度，也以独特方式回应了船体造型，彰显了对高品质细节的极致追求。

创新的结构布局与功能区域的巧妙划分：从工程角度看，项目成功解决了漂浮建筑的稳定性和空间效率问题。双体船式的钢制外壳不仅提供了必要的抗风荷载能力，其巨大的下方空间被有效用作储藏，从而使上层甲板保持了简洁的内部形象。功能布局上，桑拿主体被策略性地放置在船体中央，连接了前方的休息区和后方的淋浴房。屋顶露台的设计更是巧妙，它不仅提供了第二层观景平台，定制的雪松家具和高处的宁静感，还使得使用者在享受私密休憩的同时，获得了屏蔽水面噪音的独特声学体验。

The external form is vividly inspired by the very act of taking a sauna, questioning how one can best enjoy this activity amidst the beautiful nature of the Stockholm archipelago. The curve of the roof creates an intimate relationship between man and fire at its lowest point, then extends upwards on both sides, guiding the gaze towards the starry night sky," described architect Thomas Sandell about the design concept. The building was handcrafted by the 80-year-old master carpenter Leif Persson at the Kungsör shipyard, making the entire manufacturing process a feast of craftsmanship. The master's life experience also played a crucial role in the design of the interior and exterior furniture and wood cladding.
“外部形象的灵感来源于对蒸桑拿本身的场景想象，即如何才能在斯德哥尔摩群岛美丽的大自然中更好地享受桑拿？屋顶的弧线在其最低点处创造人与火的亲密关系，然后在两边向上延伸，把人的视线引导向夜晚的星空。”建筑师 Thomas Sandell 如此描述其设计概念。该建筑是由一位 80 岁的木工大师 Leif Persson 在 Kungsör 船厂亲手打造的，整个制造过程本身就是一场手工艺的盛宴。而大师一生的经验也对室内外家具和木饰面的设计产生了举足轻重的影响。

To maximize the closeness between people and nature for an immersive experience, the main glass sections are designed frameless. "We used brass for the helm to respond to the overall shape, and then concealed all navigation equipment within rotatable brass casings to avoid disrupting the general aesthetic," explained architect Johan Strandlund.
为了最大限度拉近人与自然的距离以创造一种沉浸式的体验，主体玻璃采用无框设计。“我们用黄铜做舵来回应整体造型，然后把所有的导航设备用可旋转的黄铜外壳隐藏起来，以免破坏总体气质。”建筑师 Johan Strandlund 解释道。

The catamaran hull is made of steel, which effectively resists wind loads, ensuring the stability of the hull. The large volume of the hull creates ample storage space beneath the deck, freeing up the space above the deck to foster a minimalist interior image. The entire wooden cabin was built separately in the shipyard and then hoisted onto the site using pre-installed hooks in the walls.
双体船的外壳由钢铁制成，这样就能有效抵抗风荷载，从而保证船体的稳定性。外壳巨大的体量在甲板下方形成了大容量储藏空间，并将甲板上方的空间解放出来，营造出简约的内部形象。整个木屋是在船厂内单独建造然后通过墙内预置的钩子吊装到场地上的。

Manufacturing a four-sided glass sauna stove from scratch was a huge challenge. We achieved success through continuous refinement with blacksmith Jan Karlsson using hand-drawn sketches and extensive testing. The interior space is entirely clad in cedar, a material also used for the external control cabinet. The exterior features a rougher pine wood texture, aiming to harmonize the façade with the surrounding coastline. Custom light switches are also made of brass and engraved with the icon of the overall shape.
从零开始制造一个四面都有玻璃的桑拿炉是巨大的挑战。我们通过手绘草图与铁匠 Jan Karlsson 不断磨合，并进行了大量测试才得以成功。内部空间完全用雪松装饰，这种材料还被用在了外部的控制柜中。外部则选择了质感更为粗糙的松木，目的是让立面与周围的海岸线和谐共生。定制的灯光开关也采用了黄铜材料，上面还印有整体造型的图标。

The sauna is centrally located in the hull, sandwiched between the lounge area at the bow and the shower room at the stern. An internal ladder leads visitors up to the roof terrace, which features custom cedar furniture where one can comfortably sit and overlook the surrounding scenery. The elevated terrace also shields against most of the noise from the water surface, creating a unique experience that is both tranquil and dramatic.
桑拿浴室夹在船头的休息区和船尾的淋浴房之间，刚好处于整个船体的正中央。内部有一个梯子把人引导向屋顶露台，那里有定制的雪松家具，游客可以舒适地坐在上面俯瞰周边景色。位于高处的露台还能够屏蔽大部分水面的噪声，由此创造出一种静谧而又富于戏剧性的独特体验。
