A dual-slope roof captures rainwater for reuse while integrating sustainable timber to enhance the connection between the interior and the surrounding forest, serving as a multifunctional space for wellness and community activities.
5 key facts about this project
01
Dual-slope roof design directs rainwater into storage tanks for sustainable reuse.
02
Cross-laminated timber panels incorporate locally sourced materials for reduced environmental impact.
03
Ventilation strategies leverage natural airflow for climate control throughout the seasons.
04
Large rooflights optimize daylighting, enhancing user experience while minimizing energy use.
05
Flexible interior spaces accommodate various community and wellness activities within a singular footprint.

The architectural project at hand is a contemporary structure designed to serve as a multifunctional facility integrated into a lush natural environment defined by a pine and eucalyptus forest. This architectural endeavor focuses on creating spaces that facilitate interaction among users while harmonizing with the surrounding landscape. The layout consists of distinct areas designated for kitchens, social gatherings, and wellness activities, including dedicated locker and shower facilities alongside a yoga hall.

The project embodies an approach that prioritizes sustainability and user experience. It leverages its geographic location to enhance natural ventilation and lighting, integrating large windows and strategically placed openings. This fosters a connection to the environment while minimizing reliance on artificial resources. The overarching design philosophy emphasizes the importance of maintaining and preserving existing pathways and natural ecosystems, ensuring that users experience the beauty of nature throughout the site.

Sustainability and Functionality
One of the primary distinguishing features of this project is its commitment to sustainable practices. The roof design showcases an innovative sloped formation that not only channels rainwater into storage tanks for reuse but also allows for the incorporation of solar panels. This sustainable approach addresses energy efficiency, showcasing that modern architecture can coexist successfully with ecological preservation.

Moreover, the use of natural materials such as timber, plywood, concrete, aluminum, and glass highlights the intention of creating a warm, inviting atmosphere without compromising durability. Each material used contributes to the building’s overall energy efficiency, helping to maintain comfortable internal climates across different seasons.

Adaptation and Flexibility
The architectural configuration enables significant adaptability in how the spaces are utilized. This design feature allows for an array of activities, from personal reflection in the yoga hall to social gatherings in the kitchen and dining areas. The open-plan layout encourages fluid movement between zones while serving the functional requirements of the space. The architectural designs reflect a thorough understanding of user needs and lifestyle, aligning physical spaces with contemporary requirements.

Natural integration represents a significant theme in the architecture. The strategic positioning of the building and its form assures minimal disruption to the existing flora and pathways. This thoughtful design consideration permits the project to complement the natural landscape, reinforcing the notions of environmental awareness and community connection.

For a comprehensive understanding of this project's architectural plans, sections, and designs, readers are encouraged to explore the full project presentation. An in-depth review will provide valuable insights into the architectural ideas that shaped this undertaking.

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.
