Cantilevered forms of Corten steel extend gracefully over Iceland's unique geological landscape, creating a Visitor Center that both educates and connects visitors with the striking natural environment.
5 key facts about this project
01
Cantilevered design allows for unobstructed views of the surrounding geology.
02
Corten steel develops a protective rust layer, ensuring durability against harsh weather.
03
Shou sugi ban cladding enhances interior warmth while improving material resistance.
04
Rainwater harvesting system provides treated water for visitor use and promotes sustainability.
05
Photovoltaic panels combined with battery storage support energy needs year-round.

The Visitor Center at Grjótagjá is located in a unique geological area of Iceland, combining architectural design with the natural environment. It serves as a space for visitors to explore and learn about the remarkable rock formations in the region. The overall design concept emphasizes educational experiences and promotes interaction with the landscape, while the building itself extends out toward the ravine, creating a balance between built form and nature.

Materials and Form

Corten steel is a primary material used in the construction, known for its strength and durability in harsh weather. This material develops a protective layer of rust that not only increases its lifespan but also allows it to blend in with the rugged surroundings. The design features sharp edges and clean lines, which guide visitors toward important geological sites like Karlagjá and Kvennagjá. The cantilevered design gives the center a lightweight appearance, ensuring it complements rather than overshadows the landscape.

Spatial Organization

The center consists of two distinct levels: the lower level includes a ramp with an interior space and a lower platform, while the upper level functions as a viewing platform. This layout supports smooth movement throughout the building and offers various viewpoints of the surrounding geological features. By positioning the center between the viewing caves, it effectively separates the different areas, creating a clear distinction between those meant for viewing and those meant for bathing.

Sustainability Measures

Sustainability is an important focus of the design. Photovoltaic panels installed on the roof provide electricity to the center, with battery storage to ensure energy is available even in less favorable weather. The design also incorporates a system for rainwater collection, allowing rain to be captured and treated for drinking. These sustainable features reflect a commitment to minimizing the ecological impact of the building while educating visitors about the local environment.

Interior Detail

Inside the Visitor Center, shou sugi ban cladding is used, providing a warm and textured contrast to the exterior Corten steel. This technique not only enhances the aesthetic appeal but also improves the wood's resilience against the elements. Natural light entering through carefully positioned openings interacts with the textures, creating a welcoming atmosphere for visitors. The thoughtful use of materials and light enhances the overall experience within this carefully designed space.

`
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.
