5 key facts about this project
01
Constructed primarily from local stone and soil, enhancing regional sustainability.
02
Circular layout promotes communal interaction and connectivity among residents.
03
Design incorporates natural ventilation strategies for energy efficiency.
04
Adaptation of ancient building techniques creates a modern interpretation of prehistoric shelters.
05
Integrated vegetation around the structure fosters biodiversity and ecological awareness.

### Overview
Located in a region rich in historical and natural significance, the project examines the interplay between human habitats and their environment, inspired by prehistoric dwelling techniques. The intent is to create spaces that foster emotional connections to nature while paying homage to ancestral living. By employing locally sourced materials and integrating natural elements, the design reflects a commitment to environmental stewardship and communal living.

### Spatial Configuration
The layout features a circular design that encourages inclusivity and interaction among users. Central gathering areas are surrounded by partitions that evoke the characteristics of primitive enclosures, facilitating a sense of community. Gentle elevations and depressions within the site mimic natural topography, allowing for a harmonious relationship with the landscape. Architectural strategies prioritize natural ventilation and light, enhancing energy efficiency while providing comfort. Vegetation surrounding the structure supports both aesthetic values and functional benefits, such as shade and air purification.

### Material Selection
The material palette is derived entirely from the surrounding environment, emphasizing sustainability and locality. Key materials include rock, pebbles, sand, soil, clay, and glass—each carefully selected for their durability and relevance to the local context. This approach not only strengthens the project's sustainability ethos but also underscores a commitment to integrating a circular economy into construction practices. Additionally, the use of glass sourced from local sand helps facilitate natural lighting and visual connections to the exterior environment, reinforcing the design's focus on blending indoor and outdoor spaces.

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.
