Maison 24 is an innovative architectural project designed with a focus on sustainability and functionality. This residential structure embodies principles of eco-friendly design and efficient space utilization while promoting a close relationship with its natural surroundings. The architecture reflects a modern interpretation of living spaces that respond dynamically to environmental conditions.

The core of the design revolves around a circular form that facilitates optimal solar exposure throughout the day. This rotation capability allows the structure to adapt as the sun moves, enhancing energy efficiency and natural light intake. The modular layout efficiently organizes living areas, including a spacious living room, functional kitchen, comfortable bedrooms, and compact bathrooms, all while ensuring seamless flow between spaces. Each area is purposefully designed to foster interaction and promote a minimalist lifestyle that emphasizes tranquility.

Sustainable material selection plays a critical role in the project. Materials such as concrete, sustainably sourced wood, and recycled components create a responsible building envelope. The use of high-performance glazing not only enhances aesthetics but also contributes to thermal performance. Proper insulation further minimizes energy consumption, making Maison 24 a model for energy-efficient residential design.

Unique design approaches set this project apart from conventional residential architecture. The circular design not only allows for a versatile living arrangement but also promotes natural ventilation and organic lighting patterns. The self-sustaining water management system, incorporating greywater recycling, exemplifies thoughtful environmental consideration. This innovative integration of technology into the structure enhances the overall sustainability profile, allowing for low-impact living.

The attention to detail within the architectural plans and sections reflects a commitment to creating spaces that are both visually appealing and functionally sound. Thoughtful design choices elevate the living experience while respecting the surrounding ecosystem. The interplay of indoor and outdoor spaces encourages residents to engage meaningfully with nature, reinforcing the project's commitment to sustainable living.

For those interested in delving deeper into Maison 24, it is recommended to explore the architectural plans, sections, and design elements further. This examination will yield insights into the innovative architectural ideas that underpin this project, showcasing how modern design can harmonize with ecological principles.

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.
