Grand Interview

Your innovative integration of the Quillayes forest into Among Quillayes Mountain Bathroom challenges traditional architectural boundaries - could you elaborate on how this harmonious relationship between built environment and nature shaped your design decisions?

The relationship with the quillayes and myrtle forest was the conceptual core of the project. From the beginning, I understood that the bathroom had to integrate into the environment without disturbing it, like a pause in the journey of the landscape. Preserving a myrtle tree in the center of the plot was not a restriction, but rather an opportunity to redefine the logic of the design. Each decision was made based on that founding gesture: instead of modifying the topography, I proposed staggered platforms that followed the natural slope. Materials such as local stone, wood and recycled sleepers were chosen for their durability and their ability to blend chromatically with the environment. The result is a space that does not seek to impose itself, but rather to partially disappear among the vegetation, inviting an experience of contemplation. It is an architecture that dialogues with nature instead of dominating it, which in itself represents a challenge to the traditional conventions of built design.

The use of reclaimed railway sleepers in Among Quillayes Mountain Bathroom presents an intriguing blend of sustainability and aesthetics - what inspired this specific material choice, and how does it contribute to the project's overall environmental narrative?

The choice of recycled railway sleepers arises from the intention to give the project a resilient and coherent materiality with the environment. This material, loaded with history and previous use, provides a visual texture and a character that dialogues with the landscape without artifice. Beyond its rustic aesthetics and great durability, its reuse represents a conscious gesture towards sustainability, avoiding the use of new wood and reducing the environmental footprint. Their presence in the project reinforces the low-impact narrative: building not from excess, but from intelligent reuse and respect for existing resources. Furthermore, the aged dark color of the sleepers allows them to visually integrate into the terrain, as if they had always been there. With this, a silent connection is established between past, present and landscape, in line with the spirit of the project.

The terraced platform design of Among Quillayes Mountain Bathroom follows the natural topography - could you walk us through the technical challenges of implementing this approach while maintaining structural integrity and minimizing environmental impact?

Implementing a terraced platform following the natural topography involved several technical challenges. Firstly, it was necessary to carry out a survey of the land to define levels without resorting to invasive cuts or filling. Each terrace had to resolve both the structural settlement and the fluid circulation, without compromising the existing vegetation or altering natural runoff. Specific and light foundations were chosen, avoiding continuous slabs, which made it possible to reduce contact with the ground and facilitate the aeration of the ground, leaving the building detached from the ground. The slope of the site also involved resolving the accessibility and stability of the construction elements, especially in an environment where rain and erosion are relevant factors. This strategy not only respected the landscape, but strengthened the idea that architecture can adapt to the terrain rather than transform it, maintaining its structural integrity with minimal impact.

Unique Properties
This design is a sustainable architectural proposal that seamlessly integrates into its natural surroundings, respecting and enhancing the existing ecosystem. What sets it apart is its focus on minimal environmental impact and the use of locally sourced, low-impact materials such as wood, natural stone, and reclaimed railway sleepers. The harmony between architecture and nature, combined with a rustic yet refined aesthetic, makes it a model of sustainability and respect for the landscape.
Dimensions & Packaging
The project measures 3.45 m in width, 2.00 m in depth, and covers approximately 7 m². The maximum facade height is 3.2 m, adapting to the roof slope and respecting the natural topography. The design harmoniously integrates with the environment, optimizing the relationship between structure, materials, and landscape.
Tags
Integration with the landscape, sustainable architecture, natural materials, adaptation to the terrain, bioclimatic design, respect for the environment, terraced platforms, vegetation preservation.
Production Technology
The design follows a contextual architecture approach, blending site analysis, digital modeling, and exploratory models. Durable materials like natural stone, concrete, recycled wooden sleepers, and wood were chosen for their environmental harmony. Terraced platforms follow the topography, optimizing views and circulation. Sustainability principles were prioritized to minimize environmental impact and enhance construction efficiency.
Design Challenge
The biggest challenge in this design was balancing integration with the natural environment while meeting local regulations and technical requirements. Adapting to the mountainous terrain and preserving a landmark tree required innovative solutions to protect the ecosystem. Additionally, selecting sustainable materials was complex due to the limited availability of local options that met durability and aesthetic needs. Overcoming these obstacles required a creative approach and thorough site analysis.
Research
The project explores how architecture can respectfully integrate with the natural landscape using sustainable materials. Data collected through site visits and analysis of locally available materials shows that natural materials strengthen the connection between the design and its environment. This approach fosters sustainable architecture by promoting environmentally respectful solutions and creating functional spaces.
Inspiration
This project integrates architecture with nature, prioritizing minimal intervention and preserving the majestic arrayán tree as the centerpiece. Guided by site-specific research, the design utilizes sustainable materials like natural stone, concrete, and wooden sleepers for durability and aesthetic harmony. The terraced platforms follow the natural terrain, ensuring a seamless connection between the built environment and the landscape.
Project Duration
The project started in March 2024 and finished in July 2024, located in the Arrayán mountain region in Lo Barnechea, Santiago Metropolitan Region, Chile.
Operation Flow
This space seamlessly blends with its surroundings, offering a welcoming and functional experience. The structure follows the land's shape, creating terraces that connect visually with the landscape. Wood and stone materials provide warmth and durability, while the layout optimizes light and ventilation. Every element is thoughtfully designed to ensure comfort and harmony with nature, enhancing the overall user experience.
