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.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
