Equipped with a bamboo cylinder for sunlight control and a rainwater-cooled ceramic air conditioning system, the cabin offers a focused, tranquil space designed specifically for meditation.
5 key facts about this project
01
Ceramic air conditioning system utilizes harvested rainwater for cooling.
02
Bamboo cylinder provides shade while allowing plants to grow.
03
Radial wall design optimizes natural light diffusion throughout the cabin.
04
Custom-made bricks reflect local traditional building techniques.
05
Flexible rolling window system maintains connectivity with the surrounding environment.

The Meditation Cabin is located in the calm landscapes of Vale de Moses, Portugal, designed for individuals seeking spaces to meditate and reflect. The design promotes a close connection to nature, allowing users to focus on their surroundings while reducing distractions. The overall concept centers on creating an environment that supports well-being and contemplation.

Key Spaces

The cabin is divided into several functional areas, including outer and inner meditation spaces, a hall, and a massage area. Each space has a specific purpose, whether for personal reflection or group activities. This thoughtful arrangement enhances the flow of movement within the cabin, encouraging users to enjoy a peaceful experience throughout the different areas.

Light and Environment

Natural light plays an important role in the cabin's design. The structure is influenced by circadian rhythms, which dictate how sunlight enters the space. A radial wall helps to disperse light evenly, providing comfort without overheating the interior. This focus on natural illumination contributes to a warm atmosphere, creating an inviting setting for meditation and mindfulness.

Sustainable Systems

An innovative ceramic air conditioning system marks a practical commitment to sustainability. Rainwater is collected from the roof and directed into a tank, where it cools the air through specially designed bricks. This system reduces energy use and showcases the project's reliance on local resources, providing an environmentally friendly approach to comfort.

Material Expression

The facade of the cabin features custom-made bricks that reflect traditional building techniques, creating a link to the cultural heritage of the region. A bamboo cylinder stands out as a key design element, offering shade to the meditation area while allowing for the growth of plants. This design detail not only enhances the cabin's connection to its environment but also maintains a natural feel.

The inclusion of a rolling window system enhances adaptability. A large circular sliding door allows users to regulate airflow and access while ensuring the interior remains connected to the outdoor surroundings. This flexibility contributes to the overall comfort and functionality of the space.

`
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.
