The project "ÍS - HOT!" is located in Iceland, reflecting the island's unique geological features and cultural heritage. The design serves as both a museum and an information center, exploring the themes of fire and ice that are integral to the Icelandic landscape. Its overall concept is influenced by volcanic forms, creating a deep connection to the surroundings while providing an underground experience for visitors.

Spatial Organization

A significant portion of the building is designed to be below ground, leading to an underground museum that mimics the experience of exploring natural caves. As visitors move through the space, they encounter a variety of narrow and wide areas that enhance engagement with the exhibitions. The journey concludes in a café where expansive views of the landscape create a strong connection between the inside and outside.

Thematic Elements

At the core of the design are two focal points known as "hearts," representing the themes of fire and ice. These elements not only reflect the cultural significance of these natural features but also help establish a cohesive architectural identity. The design allows light to play through the spaces, creating a range of moods and experiences as visitors navigate through the building.

Sustainability Features

The building incorporates renewable energy strategies, such as an aerodynamic shape that captures wind energy and the use of geothermal power. This focus on sustainability is crucial in addressing the challenges posed by Iceland's climate. By prioritizing eco-friendly practices, the architecture aligns with contemporary approaches aimed at reducing environmental impact.

Design Details

Throughout the project, attention to the surrounding landscape is evident. The café design is inspired by the northern lights, offering a colorful interior that contrasts with the natural tones outside. This detail enriches the sensory experience for visitors and reinforces the connection between the architecture and the remarkable Icelandic scenery.

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.
