05
Community involvement enhances long-term viability and resource efficiency.

Located in southern Burkina Faso, The Core addresses housing challenges faced by marginalized communities by providing a sustainable living environment. The design focuses on delivering essential services such as electricity, clean water, and sanitation, aiming to offer self-sufficient microhomes that respond to climate change, urban displacement, and inadequate housing conditions.

Spatial strategy
The microhome features a compact layout that efficiently accommodates key living functions including sleeping, cooking, working, and sanitation within an open-plan interior. Large windows and carefully positioned doors facilitate natural light and cross-ventilation, enhancing thermal comfort in the region’s hot climate while reducing dependence on mechanical cooling. The spatial organization encourages family interaction and supports flexible use of space.

Material selection and sustainability
Local materials are prioritized to support sustainability and cultural relevance. Compressed Stabilized Earth Blocks (CSEB) are employed for their thermal properties, complemented by a 3D-printed roof that functions as a rainwater collector. Eucalyptus wood is used for interior ceilings, adding durability and aesthetic warmth. Solar panels provide renewable energy, while rainwater harvesting and filtration systems ensure water availability. An incinerating toilet system addresses sanitation without relying on conventional sewage infrastructure. Community engagement in the design and construction process promotes ownership and adaptability, supporting long-term viability and resource efficiency.

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.
