Subscribers only
Utilizing screw foundations and an aluminum facade, the design achieves a compact, self-sufficient living environment that effectively captures solar energy and manages water resources.
5 key facts about this project
01
Utilizes screw foundations for enhanced air circulation and ground permeability.
02
Incorporates a dual-purpose facade that serves as both insulation and exterior cladding.
03
Employs a photovoltaic system angled for optimal solar energy capture regardless of orientation.
04
Features a rainwater management system that separates collection and usage for improved efficiency.
05
Integrates a serving function shaft housing solar storage and water filtration for centralized utility access.

The design emphasizes self-sufficient living within a small footprint. It is located in a context that values sustainability and environmental responsibility. The structure integrates renewable energy and efficient water management systems, providing a practical solution for modern housing needs aimed at reducing ecological impact.

Solar Energy Integration

The roof includes a photovoltaic system angled at less than 10 degrees. This setup allows the building to capture solar energy effectively, no matter its orientation. The design also promotes air movement, which aids in energy production. By incorporating renewable energy sources in such a straightforward way, the architecture supports eco-friendly living.

Water Management Strategies

The water management system seeks to make the most of rainwater. It captures this resource and allows it to be filtered and used for different purposes, including heating and repurposing as wastewater. By separating the water systems during collection, the design enhances overall efficiency. This approach highlights a commitment to responsible resource use.

Structural Considerations

The structure is raised on screw foundations that keep the floor plate elevated above the ground. This allows air to circulate freely and prevents the sealing of the surface beneath. By doing so, the design promotes better interaction with the environment. The use of space within the support framework is optimized, creating usable areas without expanding the overall size of the building.

Facade and Thermal Performance

The facade is both a protective outer layer and an insulation component. It is designed to maximize thermal efficiency and reduce energy loss. Included materials such as aluminum slating and clay construction boards are chosen for their beneficial properties. By maintaining low thermal transmittance, the design fits well within energy-saving goals.

Additionally, a serving function shaft incorporates solar storage and water filtration. This part of the structure serves as a central location for utilities, simplifying their use. With careful attention to design details, the building promotes a practical and sustainable living experience.

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.
