A conical structure crafted from Moso bamboo and straw bales seamlessly integrates renewable materials to foster a communal living environment focused on sustainability and interaction.
5 key facts about this project
01
Utilizes a spiral design to enhance airflow and natural light.
02
Constructed primarily with locally sourced Moso bamboo for structural integrity.
03
Incorporates straw bales for superior insulation and energy efficiency.
04
Features a solar parabolic trough for renewable energy generation.
05
Designed to facilitate community interaction through a central gathering space.

The Spirala Community Home is a thoughtfully designed architectural project that embodies principles of sustainability and communal engagement. This structure utilizes spiral geometry as its guiding motif, which not only enhances aesthetic appeal but also optimizes functionality and environmental performance. The project aims to create a welcoming environment that fosters social interaction while maintaining a minimal ecological footprint.

The design integrates five conical segments in a circular arrangement, allowing for effective space utilization. This configuration promotes airflow, maximizes natural light, and enhances thermal comfort, crucial for communal living environments. The central Community Room serves as the nexus for gatherings and activities, emphasizing the project's focus on community well-being.

Sustainable Materiality and Construction Techniques

The architectural choices exhibited in the Spirala Community Home highlight an intentional focus on eco-friendly materials. Key materials such as Moso bamboo, straw bales, cement lime mortar, mud plaster, and natural building elements have been selected based on their availability, thermal properties, and sustainability. Moso bamboo serves as a strong structural component, while straw bales provide excellent insulation, contributing to energy efficiency.

The use of cement lime mortar mixed with volcanic ash and local soil demonstrates a commitment to minimizing environmental impact. Mud plaster, applied both internally and externally, enhances climate resilience. These material choices not only enhance the building's performance but also establish a direct connection to the local ecosystem.

Innovative Design Approaches to Community Living

The design of the Spirala Community Home incorporates innovative features that enhance both functionality and social interaction. The layout promotes natural ventilation and cooling through architectural elements such as strategically positioned louvers. Additionally, a solar parabolic trough system is integrated into the building design, providing a significant portion of the energy needs through renewable sources.

The project emphasizes inclusivity through accessible design elements, including ramps that ensure all community members, regardless of mobility challenges, can access the various spaces within the home. The site plan encourages community agriculture and eco-recreation, further enhancing the connection between residents and their environment.

The architectural framework not only serves to shelter but also to engage with its surroundings, positioning the Spirala Community Home as a model for sustainable living that prioritizes both individual and collective needs.

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.
