With its half-circular modules built from locally sourced tuff and peat, the design creates a cohesive community space that integrates food production and sustainable living while serving as a welcoming residence for visitors.
5 key facts about this project
01
Half-circular module design maximizes usable space while minimizing height.
02
Tuff and peat are used for thermal efficiency, providing natural insulation.
03
Integrated greenhouse supports local agriculture and community engagement.
04
Communal kitchen fosters social interaction among guests and residents.
05
Protected courtyards enhance comfort and encourage vegetation growth.

The project in Mývatn, Iceland, focuses on creating a community that blends with the natural landscape. Set in a region known for its unique geology and ecology, the design aims to establish a series of small modular units that promote social interaction and a sense of belonging among residents and visitors. Central to the concept is the idea that homes should be warm and inviting, encouraging connections between people and their environment.

Community Engagement

At the center of the design is a communal kitchen, which is intended to be a gathering space for guests. This area is designed to facilitate shared cooking experiences, allowing residents and visitors to prepare meals together. By doing so, it helps to foster interaction and break down cultural barriers. Surrounding the kitchen are additional spaces for resting and community activities, all integrated within landscaped green areas that enhance the overall welcoming atmosphere.

Sustainable Practices

The greenhouse stands out as a key feature of the design. Its purpose is to support local food production and encourage residents to grow their own crops. This not only reinforces the connection to the land but also promotes sustainable living practices. The design also includes shaded spots for growing mushrooms and sprouts, which highlights a commitment to environmental awareness and biodiversity in the community.

Design Adaptation

The layout of the modules is carefully structured to respond to local climate challenges. It creates protected courtyards that offer comfortable outdoor spaces for relaxation and plant growth during colder months. The half-circular shape of each module maximizes usable interior space while keeping elevation low, which helps to retain warmth and enhance energy efficiency.

Materiality and Thermal Efficiency

Material choices include tuff and peat, which are used for constructing the solid walls. These materials have natural thermal properties allowing them to absorb heat during the day and release it at night. This approach not only makes the living spaces comfortable but also connects the design with its surrounding environment.

In addition to these elements, outdoor stairs lead to roof terraces, inviting residents to engage with the landscape. The inclusion of blueberry and cranberry bushes along the pathways reinforces the connection between nature and the built environment, creating a cohesive and inviting setting.

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.
