The reflective steel structure, harmonizing with the surrounding landscape and harnessing geothermal energy through an innovative design, serves as a visitor center near Karlagjá cave, inviting exploration of the area's geological features.
5 key facts about this project
01
Reflective outer skin minimizes visual impact in the natural landscape.
02
Observation platform extends into the air, offering expansive mountain views.
03
Kinetic pavement tiles generate electricity from visitor foot traffic.
04
Central skylight refracts the aurora light into the interior space.
05
Built using a steel structure that integrates with local geothermal energy.

"The Gap Flower" is a structure located near the entrance of Karlagjá cave. It serves as a visitor center and embodies the relationship between the natural landscape and built forms. Designed to represent a flower rising from an icy environment, the building reflects the contrasting elements of fire and ice that characterize the region. The project enhances public interaction with the area's unique geological features.

Design Concept

The design integrates thoughtfully with the surrounding landscape. The outer surface is reflective, allowing it to blend in with the environment and minimize visual disturbance. A central skylight plays a vital role in the design by bringing natural light into the building, creating a lively interaction of light and shadow that enriches the experience for visitors.

Program and Functionality

The facility includes essential amenities for visitors. Features such as a waiting area, an information stand, storage rooms, toilets, a café, an office, and an observation platform make the space functional. The observation platform is particularly notable, extending outward to offer expansive views of the nearby geological fissures and mountains, encouraging visitors to engage with the surrounding natural beauty.

Sustainability Features

Sustainability is a key aspect of the design. Kinetic pavement tiles are used to generate electricity based on foot traffic, demonstrating an efficient way to harness energy within the building. The design also incorporates a ground source heat pump, making use of local geothermal resources to provide sustainable heating.

Material Selection

Materials used in the project include mirror stainless steel and a sturdy steel structure. These choices not only support the structural needs but also enhance the overall appearance of the building. The reflective quality of the stainless steel strengthens the connection between the structure and its natural setting, aligning with the concept of integration into the landscape.

The upper levels provide visitors with a chance to experience the interaction of light and form, creating an inviting space that encourages exploration of the area's distinctive qualities.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
