The Hverfjall Café is located in a remarkable mountainous area of Iceland, designed to encourage visitors to connect with nature. It functions both as a café and an educational space where individuals can appreciate the region's natural features. The design revolves around creating a harmonious relationship between the indoor environment and the scenic views outside, enhancing the overall visitor experience.

Architectural Features

A prominent aspect of the Hverfjall Café is the all-around glass observatory, which invites natural light and fresh air into the area. The clear glass facade enables unobstructed views of the Hverfjall volcano, enhancing the connection to the landscape. This openness allows visitors to feel part of their surroundings, making the café not just a place to relax, but also a spot to enjoy the beauty of nature.



Layout and Circulation

Inside the café, the layout includes a central lounging area that provides a space for relaxation and observation. Above, the mezzanine level hosts the Hverfjall Volcano Exhibit. This area showcases informational brochures and interactive screens to educate visitors about the geological features of the locale. By integrating learning into the café experience, visitors gain a deeper understanding of the natural environment surrounding them.



Material Selection

Materials used in the design reflect an intent to maintain a close relationship with nature. Thermally treated lumber is chosen for the walls, offering both durability and a sustainable option. Exposed stone flooring adds a durable and textured surface that connects the café to the geological context of the region. Operable glass windows allow for controlled airflow and enhance views, providing flexibility in how the spaces can be experienced.



Interior Ambiance

The interior environment is crafted to stimulate the senses through careful design choices. Circulation paths are designed with dark wood elements and colorful finishes, creating an inviting atmosphere. LED lighting complements these materials, adding warmth and distinction to the space. The combination of these elements creates a lively setting that echoes the unique characteristics of the natural landscape, making visitors feel engaged and comfortable.

`
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.
