The design in Grjótagjá, Iceland, focuses on enhancing visitor engagement with the geothermal landscape while respecting its natural features. The overall concept aims to create a harmonious relationship between architecture and nature. Structures are intended to guide and support tourists without distracting from the authentic experience the landscape provides. This careful balance allows for a deeper connection with the site.

Main House

The Main House serves multiple functions, including a reception area, waiting room, toilets, a café, a kitchen with a common space, storage, and a garden with a fireplace. Each area is designed to encourage interaction among visitors and local communities. The garden acts as a peaceful space where guests can enjoy the outdoors. Plans for cooking events, including the preparation of local fish, highlight traditional Icelandic cuisine and foster connections between people and culture.

Tower

The Tower functions as both an observation point and an access route to the fissure, which is important to the site's geological significance. It features two staircases, allowing visitors to move smoothly between levels, connecting the landmasses symbolically. The vertical structure enhances views of the landscape, giving guests a unique perspective. The design includes flexibility, with provisions for potential future add-ons like additional rooms or energy systems utilizing wind power.

Materiality

The project integrates stone, wood, turf, and old corrugated iron, carefully selected to resonate with the natural landscape. These materials aim to complement the existing geological elements rather than overshadow them. The choice reflects an appreciation for the rugged character of Grjótagjá. The use of local materials brings continuity to the environment, reinforcing a sense of place that honors traditional architectural practices.

Circulation and Experience

The pathways are designed to guide visitors throughout the site, promoting exploration that begins with Karlagjá and leads to the Tower for expansive views. From there, visitors can enjoy a meal in the Main House. This arrangement offers a mix of experiences, emphasizing interaction with the stunning Icelandic scenery. In the garden, guests can gather, relax, and reflect on their journey through a setting that thoughtfully aligns architecture and nature.

`
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.
