The Hverfjall Coffee Shop is located in Iceland, designed to serve both a space for enjoying coffee and a welcoming spot for visitors. The design reflects the unique landscape surrounding it, aiming to create a connection between the building and its environment. By considering how people will move through the space, the design fosters a friendly and engaging atmosphere for users.

Spatial Organization

The ground floor layout includes several distinct areas that contribute to a positive visitor experience. These include an office, storage room, buffer zones, a visitor centre, a kitchen, a coffee shop, a bar, and an exhibition hall. This arrangement supports clear movement while allowing various activities to take place in designated areas. Buffer zones enhance privacy and comfort, making the environment suitable for different groups of people.

Structural Efficiency

The design features two primary sections, both scaled at 1:100, giving a precise understanding of how spaces relate to one another. This precise layout allows the coffee shop to become a central hub for community interaction. The nearby visitor centre offers essential information and enhances the experience for those arriving.

Material Considerations

Material choices balance functionality with context. The flooring system includes wood, combined with underfloor heating to ensure comfort in colder weather. The structural elements consist of sand and cement screed, along with a reinforced concrete precast floor slab, providing strength and durability. External walls use plasterboard and gypsum wall board, enhanced by a 50mm metal structure with 40mm stone wool insulation that ensures good thermal performance and sound control.

Connection to Place

A key aspect of the design is its respect for the landscape and culture of Iceland. This approach helps to create a relationship between the inside and outside of the building, reinforcing its role as a place for social gathering. The selected materials not only perform well but also relate to the volcanic nature of the area, creating a story that connects the building to its surroundings.

Above the main entrance, a broad overhang offers shelter from the elements. This feature invites visitors in while highlighting the building's simple, clear lines.

`
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.
