### Project Overview

Situated in a context that emphasizes sustainability and community involvement, this design initiative aims to address the need for affordable housing by engaging future residents in the decision-making process. The approach aligns with the United Nations’ Sustainable Development Agenda, supporting a framework that encourages residents to participate in the development and maintenance of their living spaces, thereby fostering social sustainability from the outset.

### Spatial and Community Dynamics

The design prioritizes a community-oriented residential layout, focusing on affordability, quality, and ecological balance. Central to this are modular housing concepts and prefabricated systems that facilitate self-management and shared living experiences. Initial community involvement was integral to shaping the design, reinforcing social bonds. The arrangement features distinct communal areas that promote interaction among residents, establishing a sense of belonging while preserving personal privacy through a thoughtful division of shared and private spaces.

### Material Selection and Construction Techniques

A commitment to sustainability guides the material choices, which include renewable resources such as wood that enhances carbon neutrality and provides natural insulation. The design integrates cellulose insulation to further improve energy efficiency and indoor climate control. Additionally, thin-film photovoltaic panels harness solar energy cost-effectively. The use of prefabrication techniques minimizes construction waste and ensures high-quality assembly, enabling rapid construction while reducing disruption to the surrounding community. These strategies collectively contribute to a sustainable living environment tailored to the needs of diverse family sizes and lifestyles.

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.
