### Project Overview
Located in [insert geographical location], the design reflects the region's natural landscape and cultural context. The intent is to create architecture that maintains a dialogue with its environment while meeting the functional requirements of its users.

### Spatial Strategy
The design prioritizes open spaces and fluid circulation, facilitating community interaction. Rooms are arranged to encourage collaboration and accessibility, with consideration given to multi-functional spaces that adapt to various activities. This layout promotes a sense of community while ensuring efficient use of the available area.

### Materiality and Sustainability
Material selection is fundamental to the project's character and environmental impact. The structural framework predominantly utilizes reinforced concrete for its durability, while extensive glass panels enhance natural light infiltration and visual connections to the exterior. Wood finishes add warmth, contrasting with the coolness of steel, which provides structural support. Additionally, local stone is employed in façade treatments, reinforcing the connection to the site’s geology.

Sustainability is a core theme, illustrated through features such as green roofs, rainwater harvesting systems, and the use of reclaimed materials. These strategies reflect a commitment to ecological responsibility, promoting biodiversity and energy efficiency while honoring traditional craftsmanship and local materials.

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.
