### Overview

The project is situated in a climate-sensitive environment that benefits from abundant sunlight and opportunities for natural ventilation. Its design intent focuses on creating multifunctional living spaces that cater to the diverse needs of contemporary residents while prioritizing sustainability and adaptability. The approach integrates innovative modular forms that enable flexibility, allowing spaces to evolve with the occupants’ changing requirements.

#### Spatial Configuration

The architectural layout employs a modular design strategy that promotes flexibility in living arrangements. This configuration supports distinct areas for both public and private functions, creating a balance between openness and intimacy. Public spaces, such as living rooms and dining areas, are designed to encourage social interaction, while private areas, including bedrooms with attached bathrooms, provide serene personal retreats. The integration of a 360-degree façade fosters natural light and cross-ventilation, enhancing the indoor environment.

#### Material Choices and Sustainability

The project utilizes a range of sustainable materials, including hemp blocks, which provide excellent insulation and contribute to the building's ecological footprint reduction. The exterior is complemented by anti-cracking low-density plaster and reinforced with limestone and cement for structural integrity. Interior spaces feature warm, neutral tones with engineered wood and composite materials to ensure both aesthetic appeal and practicality. Energy efficiency is achieved through the incorporation of a solar panel system and passive climate control mechanisms, while rainwater harvesting systems further enhance water conservation efforts.

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.
