At the foot of Hverfjall volcano in the Myvatn region of Iceland, a new building blends into its dramatic landscape. It serves as a coffee shop and visitor center, welcoming individuals who wish to explore the natural beauty around them. The design reflects the essence of volcanic activity, resulting in a form that is both organic and engaging.

Architectural Form

The structure features flowing curves and wavy surfaces inspired by the movement of lava. It is divided into three sections, each echoing different aspects of volcanic behavior. The first section showcases soft curves similar to the shape of lava rivers, which not only connects visually with the landscape but also allows the building to integrate harmoniously with its setting.

The design continues with a second section that rises with angular forms, capturing the unpredictable nature of flowing lava. This section conveys a sense of energy and change. The final part of the building is defined by strips that mimic the patterns created by cooling ropy lava, enhancing the connection with the geological context.

Material Integration and Sustainability

Large windows provide ample natural light and unobstructed views of the surrounding environment. The layout includes practical features such as a designated pedestrian path and parking spaces to accommodate visitors easily. To address the climate, the design employs mineral wool insulation for better thermal performance, and waterproof layers help protect the structure from harsh weather.

Interior Design and Furnishings

The interior spaces are thoughtfully designed, including areas for exhibitions that inform visitors about Hverfjall's geology. Customized furniture like the Melt Chair and Void Chair draws inspiration from the textures created by volcanic activity. Each piece not only serves a purpose but also enhances the overall connection to the natural environment.

The building's design creates a relationship between the inside and the extraordinary views outside, allowing visitors to feel surrounded by nature while enjoying a comfortable 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.
