The architectural design project titled "Spontaneous Home – The Community Home" is situated in the Spirala Ecological Village in northern Portugal. It is conceived as a response to contemporary societal needs, focusing on community living and ecological sustainability. The design integrates residential and communal spaces, promoting interaction while fostering a connection with the surrounding natural environment. The unique circular form of the structure represents unity and fluidity, while the use of local vegetation enhances the theme of cultural identity within the ecological framework.

Community-Centric Design

A central aspect of this project is its prioritization of communal living. The architectural layout features a central community area, functioning as a hub for social interaction. This space is complemented by flexible residential zones that maintain a balance between community engagement and personal privacy. The design allows for various activities, from workshops to gatherings, facilitating diverse functions.

The organically designed pathways enhance usability, guiding residents through the community seamlessly. These pathways encourage exploration while providing access to communal and private areas. The emphasis on connectivity within the project reflects a deep understanding of the role of social interaction in enhancing quality of life.

Material Selection and Environmental Integration

Careful consideration has been given to material choice, promoting sustainability and an ecological ethos. The use of hempcrete, known for its insulating properties, paired with a natural lime finish, contributes to the project's energy efficiency. These materials align with modern sustainable practices while providing a comfortable living environment.

Furthermore, the strategic incorporation of native flora, including fig trees and olive farms, both enhances the ecological footprint and anchors the project within its geographical context. The focus on natural materials and landscape integration underpins the design, allowing it to coexist harmoniously with the surrounding ecosystem.

In summary, "Spontaneous Home – The Community Home" exemplifies contemporary architectural practices that prioritize community interaction and environmental sustainability. The unique circular design, flexible communal spaces, and careful material selection distinguish this project from typical community housing developments. For additional insights into the architectural plans, designs, sections, and ideas that define this project, readers are encouraged to explore the full presentation.

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.
