The design integrates harmoniously with its surroundings, presenting a structure that embraces the interplay of light and shadows. Located within a landscape that highlights this duality, the building serves as a home while exploring the depths of human experience. The central concept revolves around two symmetrical voids known as "day" and "night," which are positioned against a long thermal rammed earth wall. This framework promotes a smooth flow between inside and outside spaces, encouraging a rich interaction with various light conditions.

Conceptual Framework

At the heart of the design is a balance between light and darkness, inviting users to appreciate both elements. The elongated thermal rammed earth wall acts as a focal point, establishing a visual connection between the voids. This setup encourages inhabitants to navigate through the house, reminding them of the cycles of life and how perception of light is enhanced through contrast with darkness.

Spatial Organization

Inside, the layout is thoughtfully arranged around a central courtyard, promoting movement and connection between different areas. The journey begins in the work space and living room, progresses through the kitchen and dining room, and intentionally sidesteps the bathroom, allowing for a more open flow. This sequence reflects everyday life and cultivates a sense of continuity throughout the spaces.

Light and Atmosphere

Vertical movement within the design reveals an engaging play of light and shadow. As occupants descend into the structure, the atmosphere changes, enriching their experience. The bedroom features a large opening to the night sky, which brings in soft moonlight and stars. This connection to the celestial adds a peaceful quality to the space, fostering relaxation and quiet reflection.

Materiality and Sustainability

Employing thermal rammed earth as a primary material supports both structural stability and energy efficiency. This choice aligns with sustainable practices, blending the building with its landscape while promoting indoor comfort. The material also assists in regulating temperature throughout the interior, underscoring a commitment to environmental considerations.

Over the central courtyard, a carefully designed skylight allows sunlight to filter down, creating a beautiful play of light patterns across the interior spaces throughout the day.

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.
