### Overview

Wadi House is situated in the Arabian Peninsula, an area characterized by extreme climatic conditions that demand innovative architectural solutions. The design integrates modern principles with local environmental and cultural contexts, promoting both comfort and sustainability in residential living. The name "Wadi," which translates to riverbed in Arabic, reflects the intent to create a sense of movement and connection within the arid landscape.

### Spatial Strategy and Community Focus

Central to the Wadi House design are natural courtyards that serve as communal spaces, facilitating family interactions and a sense of community. The layout is modular, allowing for future flexibility and growth, thus meeting the evolving needs of its residents. Traditional elements, such as a Majlis, are incorporated to honor local heritage while embracing contemporary design, creating spaces that support social cohesion.

### Materiality and Environmental Integration

Wadi House employs a range of sustainable materials, including 3D-printed earth-based components that offer thermal mass and eco-friendliness. Solar panels are integrated into the structure for renewable energy generation, while local timber contributes to the authenticity of the design and minimizes transportation emissions. Porous concrete used in the walls enhances airflow, creating a more conducive indoor climate.

The design features a double façade inspired by mashrabiya, which provides shade and privacy while maintaining aesthetic harmony with the surrounding environment. Advanced water management systems, including an integrated qanat, help collect and utilize rainwater efficiently. The thoughtful positioning of the building maximizes natural ventilation, reducing reliance on mechanical cooling and ensuring a comfortable indoor climate year-round.

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.
