The Gròtagjá caves in northern Iceland provide a dramatic setting for a visitor center that connects the built environment with unique geological features. Designed to serve as both a functional facility and an experience hub, this space highlights the region's geothermal springs and striking lava rock formations. The overall concept focuses on fostering a meaningful interaction between visitors and the surrounding landscape, reflecting Iceland's deep cultural ties to nature.

Spatial Organization

The visitor center's layout is carefully planned to enhance the experience for those who enter. Key areas include a reception area, changing rooms, staff quarters, and a café, providing essential services while allowing for easy movement throughout the building. As visitors explore, they are guided naturally through thoughtfully arranged spaces. An elevated viewing platform grants expansive vistas, connecting guests with the overall narrative of the Icelandic landscape.

Architectural Form

The building features an angular silhouette that mirrors the rugged geology of the area. This distinct shape is both a visual landmark and a source of shelter and comfort within the landscape. Skylights are strategically placed to bring in natural light, creating a welcoming atmosphere inside. The geometry of the structure serves to reinforce its connection to the environment while offering an engaging visual experience.

Material Selection

The choice of materials reflects a commitment to sustainability and harmony with the landscape. Features such as double-glazed skylights provide ample light while maintaining energy efficiency. Stone slate roofing blends the structure into its surroundings, creating a cohesive appearance. The interior is finished with cross-laminated timber, which adds warmth and comfort. Steel frames ensure durability, supporting the building's structure against the elements.

Design details include a private pathway leading to the changing rooms, designed to minimize environmental impact while providing privacy for visitors preparing to enjoy the geothermal springs. The careful play of light and shadow throughout the space enhances the connection between the architecture and the natural surroundings, creating a sensory experience that invites reflection and exploration.

`
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.
