NOCTURNAL explores the connection between light and nature. It integrates the idea of bioluminescence into its design, creating a building that illuminates at night. Located in an area focused on sustainable innovation, the building serves public and private functions. The overall design concept draws directly from plants that naturally glow, influencing both the form of the building and how people experience it.

Bioluminescent Inspiration

The design draws lessons from engineered tobacco plants that emit light through a biological process. These plants convert caffeic acid into luciferin, resulting in a natural luminescence. In the project, this concept is translated into a structure that can glow in the dark. This unique feature not only enhances the visual appeal but also creates an environment that shifts with time, engaging those who use it.

Sliding Petals and Spatial Dynamics

A striking feature is the sliding petals, which react to sunlight and shadow throughout the day. They provide shade when needed and enhance brightness at night. The configuration includes both public gathering spaces and private retreats, allowing users to connect with one another or find solitude as they prefer. Outdoor areas blend with greenery, creating a balance between community and personal space.

Light-Mitigating Structures

Sun tunnels and solar tubes enhance the building by maximizing natural light. Skylights are placed to increase brightness inside and offer views of the sky. These elements are not just functional; they add interest to the architecture. The design emphasizes light as an integral part of the structure, making the building a vibrant space to inhabit.

Material Choices and Architectural Elements

The roof, made primarily of glass, is a crucial feature, allowing for transparency and light flow. This choice reflects an intention toward sustainability, enabling the structure to use natural light effectively. The glass creates a special atmosphere, making the interior feel connected to the outside. At night, the glowing structure stands out against the dark sky, presenting a bold interaction between architecture and nature.

The incorporation of bioluminescence into the building design offers a fresh perspective on how light and space can work together. The project emphasizes the relationship between the natural environment and human habitation, creating a unique place that evolves throughout the day and night. With each moment, the spaces within come alive through light, inviting exploration and connection.

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.
