5 key facts about this project

02
Features an innovative layout that fosters community interaction through an open square.
03

04

05

The design responds thoughtfully to a complex landscape marked by fractures, gorges, and creeks. Set near Lake Myvatn, it comprises five buildings that accommodate various functions while harmonizing with the natural surroundings. Inspired by the simple form of traditional houses, the layout reflects the intricate nature of the site, promoting community engagement and interaction.

Functionality and Layout
An info-point establishes the first point of contact, positioned parallel to the main road for easy visitor access. This location allows for clear views of Lake Myvatn, enhancing the experience from the start. Two additional buildings for office space are arranged to create an open square. This square encourages social interaction and connects the everyday urban experience of Reykjahlid with the heart of the design.

Exhibition Spaces
Central to the layout is an exhibition area on two levels that offers significant views of Hverfjall volcano. The careful placement allows visitors to engage with the space and installations while appreciating the natural scenery. The flow of movement directs attention to the landmark, creating a strong connection between the architecture and its environment.

Material Considerations
Material choices reflect both function and sustainability. Key elements include horizontal sondes for geothermal heating, lean concrete, and reinforced concrete slabs, which provide necessary strength. Local materials like volcanic stone and bricks help integrate the buildings into their setting. These choices highlight a commitment to using what is available, ensuring the design resonates with its context.

Structural and Aesthetic Features
The architecture features various structural components, including glass wool panels that enhance insulation and steel beams that form a solid framework. The use of polycarbonate panels allows natural light to brighten the interiors, promoting an inviting atmosphere. These design decisions result in a cohesive environment that honors the landscape while being mindful of practical requirements.

In this design, a blend of contemporary elements and traditional forms creates an interesting architectural expression. The exhibition area, with its large windows, frames stunning views of Hverfjall volcano, encouraging visitors to connect with the beauty around them.

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.
