### Overview

Located at the end of a garden within a suburban residential area, the Art Hut is a one-room art gallery designed for solitary use. With a footprint of approximately 14 square meters, it serves as both a space for artistic expression and a platform for celestial exploration. The strategic positioning of the structure allows for views of the Atlantic Ocean to the west and mountains to the east, creating an enriching context for reflection and interaction with nature and art.

### Spatial Configuration and Materiality

The architectural form of the Art Hut features a pitched roof that culminates in a peak, reminiscent of traditional structures while maintaining a contemporary aesthetic. Its exterior is clad in black timber, which offers a striking contrast to the surrounding greenery. This choice of material not only ensures structural integrity but also fosters a harmonious relationship with the natural environment. Full-height windows on the southern facade allow natural light to penetrate the space, creating a dynamic interplay of illumination that enhances the viewer's experience of both the artworks and the surrounding landscape.

The interior layout is designed for flexibility, accommodating varied art installations while promoting fluid movement throughout the space. This adaptability is crucial for user engagement, as the design encourages interaction with both the displayed art and the celestial environment beyond. High-level windows serve as observation points, immersing visitors in an atmosphere that emphasizes the relationship between art and the night sky.

### Sustainability and Environmental Integration

The Art Hut incorporates sustainably sourced materials, primarily timber, aligning with eco-friendly architectural practices. Its minimal footprint reduces land disturbance while maximizing the potential of the site’s natural features. By integrating the structure with its surroundings, the design reflects a commitment to ecological stewardship, reinforcing the connection between artistic endeavors and the natural world. The careful arrangement of windows not only enhances natural light but also facilitates a dialogue with the external environment, blending the experiences of art appreciation and stargazing.

`
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.
