## Project Overview
Located in a sun-drenched region, the House of the Future prioritizes sustainability, adaptability, and advanced technology in its design. The project integrates ecological design principles with contemporary needs, creating a residence that addresses both environmental factors and the changing dynamics of modern living.

## Spatial Strategy and Layout
The design employs a dual-layer architectural approach, distinguishing between a solid, permanent base and a more flexible upper volume. This configuration facilitates an evolving interaction between indoor and outdoor spaces while promoting accessibility across various house levels. The basement contains utility areas, including mechanical systems and storage, and is soundproofed for privacy. The ground level features communal spaces such as the living room, kitchen, and dining areas that connect seamlessly to outdoor elements, enhancing natural ventilation. Upper levels are dedicated to private rooms with adjoining bathrooms, ensuring personal comfort and expansive views.

## Materiality and Sustainability
The careful selection of materials contributes to both the aesthetic and ecological aspects of the house. Reinforced concrete serves as the main structural component, ensuring durability, while aluminum frames and glass panels maximize energy efficiency and natural illumination. Natural stone accents reflect local geological characteristics, and extruded polystyrene is utilized for effective insulation. Key sustainable features include hybrid solar panels for energy production, geothermal systems that leverage stable underground temperatures, and dedicated water management systems designed for efficient recycling and irrigation. Landscaping incorporates local plant species to reduce water consumption and improve air quality, further supporting the residence's commitment to sustainability.

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.
