Disappearance into Mývatn Hills explores the relationship between architecture and the natural environment in Mývatn, Iceland. It emphasizes continuity by merging the structure with the landscape while providing a space for community interaction and agricultural research. The design favors simplicity and clarity, allowing the building to integrate well with its rural context.

Design Concept

The vision for this building relies on connecting with the surrounding landscape. The structure adapts to the terrain, creating visual links with the open vistas. Long sightlines invite occupants to engage with the extensive natural scenery. Sustainability plays a key role in this vision, focusing on ecological balance and addressing the community's needs.

Efficiency in Planning

The design prioritizes efficiency in its planning process. It considers environmental impacts relating to soil, energy sources, air quality, and waste management. The spatial organization across multiple levels enhances access to essential public services. A centralized hangar structure serves to strengthen social and economic connections in the area, creating a functional environment for the community.

Functional Areas

A notable feature is the greenhouse located on the top floor. This area serves as a research center and supports local agriculture, reflecting the commitment to sustainable practices. Various functional spaces accommodate community activities, including an operating sector, visitor and study areas, offices, a cafe, and a multipurpose community room. This design promotes interaction among residents and visitors, fostering a sense of community.

Architectural Characteristics

The building's appearance features clean lines and contemporary forms that relate to its natural surroundings. Large windows provide ample views while enhancing thermal performance and creating a pleasant interior climate. The glazing allows natural light to fill the main areas, reducing the need for artificial lighting and supporting energy efficiency.

The roof merges with the slope of the hill, echoing its shape and welcoming the surrounding environment. This detail allows nature to play a role in the architecture, reinforcing the overall concept of sustainability and connection to the landscape.

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.
