Employing aluminum cladding and sheep wool insulation, the center integrates with the unique landscape of Iceland's black lava fields while serving as a multifunctional space for visitors.
5 key facts about this project
01
Aluminum cladding provides lightweight protection against harsh weather.
02
Sheep wool insulation enhances thermal efficiency while being locally sourced.
03
Prefabricated cross-laminated timber panels reduce construction time on site.
04
The design includes an avalanche barrier integrated into the structure.
05
The local black stone foundation visually connects the building to its landscape.

The Visitor Center in Iceland's black lava fields serves as a facility designed to enhance visitor experiences while respecting the surrounding landscape. It is a reinterpretation of traditional turf houses, reflecting local culture and history. The building's layout emphasizes accessibility and interaction, creating a space that encourages exploration of the unique geological features of the area.

Design Concept

The layout of the center is arranged to provide clear functional spaces that cater to visitors’ needs. Features such as restrooms, showers, offices, and storage areas are designed to support the operational necessities of the center. Additionally, the inclusion of an exhibition space, playground, and café encourages social engagement and learning. Pathways lead to viewpoints and trails, allowing visitors to naturally flow from indoor spaces to the outdoor environment.

Material Selection

The exterior of the center is clad in aluminum panels. This choice is practical, as the panels are lightweight and resist harsh weather conditions. Sourcing materials locally decreases environmental impact and aligns with sustainability goals. Within the building, sheep wool insulation provides effective thermal performance, ensuring a comfortable atmosphere for users.

Structural Elements

Prefabricated cross laminated timber (CLT) panels comprise the structural framework of the center. These panels are delivered by helicopter, which makes it easier to construct in remote locations. The glue laminated timber structure not only supports the building’s form, but it also functions as protection against avalanches, adding a layer of safety. The design remains practical while also fitting into the rugged landscape.

Foundation and Landscaping

The foundation features a mix of metal grating flooring and local stone sourced from the immediate area. This approach not only supports the building but also ties it visually to its surroundings. By using black stone, the design reflects the volcanic landscape, integrating natural elements into the built environment. The careful choice of materials and the attention to site context highlight a commitment to creating a functional and meaningful space within the unique Icelandic terrain.

`
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.
