"Haven on Earth" is an architectural design situated near the Serra de Estrela mountain range, specifically close to the Vale de Moses Yoga Retreat. The aim is to create a refuge that merges with the forest environment, highlighting the importance of sustainability and the comfort of its users. The overall design concept revolves around an elevated living space that reduces its impact on nature while fostering a strong connection between residents and the outdoors.

Elevation and Form

The Pod is built above ground, which minimizes disruption to the surrounding ecosystem. This elevation not only lessens the ecological footprint but also provides residents with distinct views of the landscape. Large windows are a key feature, offering expansive vistas and allowing natural light to flood the interior, enhancing the feeling of being surrounded by nature.

Interior Layout and Spatial Organization

Inside, the layout consists of two distinct areas: a bedroom equipped with a custom table-bed and a bathroom divided into three separate zones. Skylights add to the overall brightness of the space and create a sense of openness. This thoughtful organization promotes both comfort and practicality, ensuring that the living space feels cozy while maintaining a strong relationship with the environment.

Sustainable Features and Materiality

Timber is the primary material used in the Pod, reflecting a choice for renewable resources and enhancing the health benefits for its occupants. The natural qualities of timber support a smooth integration with the surroundings, which aligns with the project's focus on ecological responsibility. Additionally, features like a composting toilet and a gray water recycling system demonstrate an awareness of sustainable practices.

Architectural Performance

The design emphasizes effective solar panel orientation to maximize sunlight exposure and improve energy efficiency. Natural ventilation is facilitated through the use of sandwich panels, contributing to a comfortable indoor climate. The lightweight steel structure allows for quick assembly, minimizing the need for extensive site work, which aligns with the project’s respect for its natural setting.

The interior environment focuses on sensory experiences that enhance well-being. The design protects against external noise and temperature issues while welcoming natural sounds and light into the living space. This creates a balanced atmosphere where residents can feel connected to the natural world outside.

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.
