Incorporating geothermal heating and sunlight-responsive paneling, the facility harmonizes with the volcanic landscape while providing a versatile space for visitors to relax and learn.
5 key facts about this project
01
Integrates geothermal energy for heating through radiant floor systems.
02
Facade panels represent monthly sunlight variations, enhancing visual interest.
03
Panelized construction allows for efficient offsite fabrication and assembly.
04
Large operable skylights promote natural ventilation and daylight.
05
Designed as a multifunctional space for relaxation and education for visitors.

The Iceland Volcano Coffee Shop is located in a landscape shaped by volcanic features. Designed to be a gathering place, it serves visitors before and after their adventures to the nearby volcano. The overall design concept focuses on sustainability and energy efficiency, creating a warm and inviting atmosphere that encourages relaxation and social interaction.

Panelization and Layout

The building employs a panelization system, allowing for offsite fabrication of walls and roofs. This strategy improves construction efficiency and enables quick assembly on location. The layout includes exhibition spaces, lecture areas, and a coffee shop, making it a multifunctional environment. Large restrooms and sufficient office spaces contribute to the building’s usability and enhance the visitor experience.

Sustainable Energy Strategies

Sustainability is a key focus of the design. Geothermal energy is used for heating through radiant floor systems, showcasing a commitment to local energy sources while reducing the impact on the environment. This choice aligns well with the building’s ecological context, ensuring efficient operation and comfort for all occupants.

Light and Facade Design

Natural light enhances the indoor environment, as large skylights and extensive glazing allow sunlight to fill the space. This reduces the need for artificial lighting, creating a brighter, more welcoming atmosphere. The facade reflects changes in sunlight throughout the year. Each panel corresponds to the monthly variations in solar exposure, with narrow glass openings providing visual interest and connection to the outside.

Materials and Context

The exterior incorporates high-performance precast concrete, selected for its strength and durability. This choice of material connects the building to the surrounding landscape, as it utilizes resources found locally. The thoughtful use of concrete reinforces the relationship between the structure and its environment, merging the natural characteristics of the site with practical building needs.

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.
