The VALE DE MOSES meditation cabins sit in a peaceful forested mountain valley, designed to create quiet spaces for meditation and contemplation. The overall design focuses on sustainability and a close relationship with nature. The cabins have a simple rectangular shape and a pitched roof, reflecting the style of local buildings while minimizing their impact on the environment.

Design Concept

The cabins are designed to be energy-efficient and self-sufficient. Large full-height windows on the southern side allow plenty of natural light into the interior spaces and provide views of the surrounding woods. This orientation benefits from the area's continental climate, where winters are cool and summers are warm. Natural ventilation is a key feature, reducing the need for artificial cooling and creating a comfortable atmosphere inside.

Materials and Insulation

Sustainability is further reflected in the materials used for insulation. Treated animal wool, straw, and cork are chosen for their thermal properties, keeping the cabins warm during colder months. These materials are more environmentally friendly than traditional options. By utilizing these natural insulators, the design can maintain a comfortable indoor climate without excessive energy use.

Water and Energy Management

The cabins utilize an innovative approach to water management. A fillable and transportable water tank accommodates the low rainfall in the area, simplifying the need for complex plumbing. Greywater is collected and used for watering plants, which aligns with the goal of conserving resources. Solar panels on the roofs generate electricity, making the cabins less dependent on external energy sources.

Indoor and Outdoor Flow

The interior spaces are adaptable, inspired by traditional Japanese ryokan inns that focus on simplicity and tranquility. Full-height cabinetry organizes therapeutic items while keeping the areas tidy and calm. A large timber deck provides a transition from inside to outside, allowing residents to enjoy nature and participate in small group activities. Natural wood finishes throughout add warmth to the cabins, creating inviting and comfortable environments for relaxation and meditation.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
