"JAVA MEETS LAVA" is a coffee shop situated at the base of the Hverfjall volcanic crater, designed to blend with its remarkable natural setting. The structure features an open cuboid tower that rises from two gentle slopes covered in turf, establishing a connection between the building and its volcanic environment. The design emphasizes harmony with the landscape and provides a welcoming space for visitors.

Form and Structure

The building's form is notable for its solid appearance, avoiding conventional entry points like doors or windows. This lack of clear signage encourages curiosity among passersby. As people approach, they see light streaming from the tower's openwork design. This not only creates an inviting atmosphere but also allows for dynamic changes in light throughout the day, enhancing the interior experience.

Materials and Sustainability

Reinforced concrete forms the main structural elements of the building, ensuring durability while maintaining thermal efficiency through thick insulation. The exterior is finished with charred timber, a material choice that reflects the volcanic context and protects against harsh weather conditions. The use of energy-efficient glass systems also minimizes heat loss, contributing to the building's sustainability.

Interior Organization and Visitor Experience

Most spaces are arranged on the first floor, including a coffee shop, visitor center, exhibition area, and retail spaces. This layout encourages social interaction among visitors, making it easier for people to move between different functions of the space. A staircase runs through the exhibition area, leading to a rooftop viewing platform that provides wide views of the adjacent volcanic landscape.

Connection to Landscape

The turf slopes surrounding the building contribute significantly to its design. These slopes provide vibrant greenery during warmer months, contrasting sharply with the stark volcanic background. They also serve as outdoor seating areas, fostering social gatherings and enhancing the overall visitor experience.

On the rooftop, the viewing platform allows guests to take in panoramic views of the area, linking them not only with the coffee shop but also with the vast beauty of the volcanic 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.
