Along the serene shores of Lake St. Moritz in Switzerland, a distinctive timber structure named Lacum Respira, conceived by .ket bureau, gently nestles within a landscape celebrated for its rich seasonal traditions and a long-standing appreciation for outdoor pursuits. This architectural creation sensitively acknowledges its breathtaking surroundings, where the expansive lake serves as both an immediate focal point and a distant vista. The tranquil setting is characterized by its open-air ambiance and majestic mountain backdrop, making every architectural gesture profoundly significant. This initiative strives for an organic integration with the environment through its selection of materials and its strategic placement along the waterfront.
In crafting this lakeside sanctuary, the designers at .ket bureau undertook an in-depth study of St. Moritz's indigenous wooden buildings, meticulously analyzing their proportions and roof designs. The outcome is a structure that reinterprets these traditional elements through a contemporary lens, presenting a long, low profile that delineates the boundary between solid ground and water. The pavilion gracefully adapts to the natural contours of the land, allowing the topography to dictate its shape and cross-section. This approach yields a form that harmonizes with the visual rhythm of the landscape, featuring sloping surfaces that echo nearby landforms and precisely positioned openings that offer sweeping views across the Engadin lake.
The pavilion's design facilitates a natural progression from more enclosed areas to open terraces and a pier, ensuring a fluid transition between interior and exterior spaces. Expansive glazing is critical in shaping the visual experience, allowing abundant natural light to penetrate deep into the structure and reflecting the lake’s dynamic surface onto interior walls throughout the day. The interplay of varying ceiling heights and enclosures further enhances spatial diversity, ranging from large communal areas to intimate zones dedicated to relaxation. The pier extends from the main structure, serving as a vital link between the urban edge and the lake, guiding visitors towards expansive views. Moreover, accessible roof areas provide elevated vantage points, reinforcing the pavilion's profound connection with the lake as a vibrant, living entity. The constant interplay of water, air, and light with the structure profoundly influences the architectural experience, adapting beautifully with the changing weather and seasons.
The essence of this project is deeply rooted in wood, which defines both its structural integrity and its aesthetic appeal. The primary structural framework is crafted from locally sourced ash, chosen for its exceptional strength and thermal properties, while larch, known for its resilience, is utilized in the pier and vertical supports, making it ideal for the lakeside environment. The use of natural oils and protective finishes, specifically chosen for alpine conditions, ensures the longevity of the materials, allowing them to age gracefully while maintaining subtle variations in character. Furthermore, the reliance on natural ventilation and daylight significantly reduces the need for mechanical systems, aligning the pavilion's environmental performance with its understated yet sophisticated design philosophy. This holistic approach ensures that the pavilion not only serves its functional purpose but also enhances the natural beauty of its surroundings, promoting a harmonious coexistence between human design and the natural world.
