"Walk Between, Walk Within" is set in a landscape defined by the geological rift between North America and Eurasia. It functions as a visitor center, inviting people to explore and connect with the natural surroundings. The design features a split form, highlighted by two gabled towers that represent the rift. These towers create a recognizable entrance and establish a strong visual identity for the building.

Form and Structure

The building's form includes a valley that rises towards the entrance. This upward motion creates a strong interaction between the structure and the site, capturing attention and framing views of the landscape. A pathway bridge connects the two towers, allowing for movement while also acting as a viewing platform. Visitors can step onto this bridge to take in the natural features around them, including the Grjótagjá caves and the Hverfjall volcano.

Interior Layout and Circulation

The layout inside has been carefully designed to guide visitors through the space. A straightforward circulation path leads from the south wing up to a café lounge on the second floor. This space encourages social interaction. After enjoying the café, visitors flow down to the exhibition area before exiting through the north wing. The arrangement fosters a connection with the surroundings while providing an organized experience.

Materials and Finish

Local materials play an important role in connecting the design to its environment. The inner roofing is made of Alta stone slate, which presents a textured surface. The exterior is covered in matte black metal sheets. Glue laminated timber forms the structure, emphasizing sustainability and enhancing the visual qualities of wood.

Spatial Experience

Inside, a tall wooden ceiling slopes inward, merging the two roof forms. This design detail mimics the experience of walking through a cave, creating an engaging atmosphere. Two spiral staircases provide access to a rooftop observation platform. From here, visitors can enjoy panoramic views of the landscape, strengthening the relationship between the building and the natural world.

`
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.
