A spiraling green skin crafted from bamboo envelops a multifunctional community space, fostering engagement and sustainability in a unique architectural expression.
5 key facts about this project
01
Spiraling "live" green skin enhances biodiversity and thermal performance.
02
Flexibility allows the pavilion to shift between insulated and open environments.
03
Community involvement is integral, with workshops for skill-sharing during construction.
04
Bamboo, a locally abundant material, serves as the primary structural element.
05
The design incorporates natural light through extensive skylights in the roof.

The "Living Spirals" project stands as a notable example of sustainable design, situated in the diverse landscape of Portugal. It focuses on creating spaces that foster community interaction while applying principles from circular economies and cradle-to-cradle philosophy. At its core, the Spirala Community Home features a circular layout, allowing flexibility in its use. This design is meant to support a variety of social activities, encouraging a sense of belonging among its users.

Design Approach

The approach taken emphasizes community participation at every stage. Local residents are invited to engage not only in the planning stages but also in the building process itself. Workshops are designed to help people learn skills that will enable them to contribute to construction and future upkeep. This involvement creates strong connections between the community and the space, fostering a collective responsibility toward the home.

Spatial Configuration

The main space within the Spirala Community Home is unique for its ability to transition between different forms. It can shift from a closed, insulated environment to an open, interactive pavilion. This change is made possible through sliding shutters, which adjust according to the climate and the needs of the people using the space. This versatility means the area can comfortably host various events, from workshops to casual meetings.

Green Integration

A significant feature of the design is the spiraling "live" green skin that wraps around the community space. This element not only improves insulation but also accommodates recreation and exhibition activities. Incorporating local plants reinforces a connection to the surrounding environment, promoting biodiversity. In addition, the green skin enhances the visual appeal, making the building a dynamic part of its setting.

Material Considerations

Sustainability plays an important role in material selection. Bamboo, known for its rapid growth and abundance in Portugal, is used in the construction. This choice not only reflects environmental responsibility but also supports local economies. Key elements like a light-weight roof with skylights allow for ample natural light, ensuring an energy-efficient design that aligns with the project's principles.

The "Living Spirals" project exemplifies a harmonious blend of nature, community, and thoughtful design. The spiraling green skin acts as a living feature, symbolizing the important relationship between built spaces and the natural world. This approach to architecture creates an inviting atmosphere that encourages interaction while remaining attuned to its environmental context.

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.
