5 key facts about this project
01
Potted coffee plants are integrated throughout the café, enhancing the overall experience.
02
The building features a multi-slope roof design that mimics local volcanic formations.
03
Cross-laminated timber construction promotes sustainability and reduces carbon footprint.
04
A fire pit at the entrance encourages outdoor gatherings and community interaction.
05
The museum area adopts a minimalist design to focus attention on volcanic exhibitions.

JLava is a coffee shop located at the foot of Hverfjall volcano in Iceland, combining coffee culture with the powerful character of its environment. The design focuses on the interplay between the building and its natural surroundings, creating a space that serves both coffee and educational displays about the local geology. Visitors experience a strong connection to the volcanic landscape while enjoying a casual atmosphere.

Architectural Concept

The design of JLava is inspired by the active volcanic landscape around it. Features include irregular shapes and a series of linked modules that resemble traditional Icelandic peat houses. This choice reflects a commitment to local architecture while presenting a modern twist. The roof has multiple slopes, echoing the natural lines of the terrain and enhancing the relationship between the structure and the landscape.



Materials and Sustainability

The building incorporates Cross-Laminated Timber (CLT) for its structural components, highlighting a focus on sustainability. This material choice supports an eco-friendly approach while creating a warm, inviting space. Additionally, the use of ecological cellulose insulation improves energy efficiency, contributing to a comfortable indoor environment without sacrificing environmental responsibility.



Interior Design Elements

Inside, the café area features many potted coffee plants, immersing guests in the coffee experience. This greenery not only beautifies the space but also encourages a climate of connection with nature. In contrast, the museum area adopts a minimalist appearance, guiding attention toward the volcanic exhibition and providing educational insights about the geological history of the region.



Design Features

A significant detail is the fire pit located at the entrance. It serves as a gathering spot for visitors, enhancing outdoor interaction and fostering a sense of community. The combination of dark wood on the exterior with the lively green of the plants creates a balanced visual appeal. The design effectively emphasizes the relationship between the structure and the natural volcanic landscape, inviting exploration and engagement.

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.
