The architectural design project "Buy-Build-Adapt" aims to address housing shortages in underserved communities by providing a framework for self-construction. This project employs a modular design approach that allows individuals and families to build, modify, and expand living spaces as needed. The architecture represents sustainability, accessibility, and community empowerment, reflecting the pressing need for affordable housing solutions.

The project emphasizes the importance of local materials and labor. Its modular structure consists of a skeletal galvanized steel frame, which supports walls made from recycled wood and plastic blocks. This combination not only enhances durability but also incorporates sustainable practices, minimizing waste. The corrugated iron roofing allows for effective rainwater runoff and houses photovoltaic panels, promoting energy efficiency. Large windows facilitate natural ventilation and lighting, contributing to a comfortable living environment.

Design features include a grid system that allows for easy adjustment and expansion of living spaces. This adaptability is critical, as it permits families to grow their homes in response to changing needs. The project also integrates basic resources such as water storage tanks for rainwater collection, further supporting sustainability and self-sufficiency.

The modular design aspect distinguishes "Buy-Build-Adapt" from typical housing projects. While many designs consist of fixed layouts, this project offers flexibility, allowing users to customize their environments. The emphasis on engaging users in the construction process fosters a sense of ownership and promotes community interaction. This participatory approach not only builds houses but also encourages community development and resilience.

Additionally, the design incorporates innovative techniques that streamline the assembly process. The use of a standardized grid layout ensures that individual components can be easily connected, making the construction of homes straightforward and manageable, even for those with limited experience in building. This technical simplicity is a significant step forward in making housing more accessible to various demographics.

To gain a deeper understanding of the architectural plans, sections, and innovative design ideas that shape this project, readers are encouraged to explore the full project presentation. This resource provides insights into the construction methodology and highlights the potential impact of the "Buy-Build-Adapt" initiative in addressing housing challenges within vulnerable communities.

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.
