The Spirala Community Centre is an architectural project designed to serve as a multifunctional facility for the local community in Coimbra, Portugal. The design integrates sustainability and community engagement into its core, utilizing eco-friendly materials and innovative structural systems. The spiraled architectural form is not only visually compelling but also functional, allowing for various activities within its adaptable spaces.

The community centre represents a response to contemporary social needs, providing a venue for educational workshops, recreation, and communal gatherings. The organic shape of the building fosters a sense of inclusivity, drawing people into its central spaces while promoting interaction among users. The project’s vision is rooted in enhancing community identity and resilience, making it a vital part of urban life in Coimbra.

Sustainable Material Use and Innovative Structural System

One of the key differentiators of the Spirala Community Centre is its emphasis on sustainable material use. Bamboo is employed as the primary structural element due to its remarkable strength-to-weight ratio and rapid replenishment cycle. This choice reflects a commitment to reducing the ecological footprint of the project. The incorporation of natural fiber panels and recycled materials enhances thermal insulation while supporting the project's overall sustainability goals.

The structural system features composite arches and reciprocal spars that provide stability and allow for expansive internal spaces without compromising safety. The use of fenestration is also noteworthy, as strategically placed windows enhance natural light penetration, contributing to energy efficiency and creating a pleasant atmosphere for users.

Functional Layout and Versatility

The layout of the Spirala Community Centre is designed for versatility, facilitating a range of activities under one roof. The open-plan design allows for fluid movement between spaces, encouraging spontaneous interactions among visitors. The central dome acts as the heart of the facility, designated for larger gatherings and workshops, while smaller breakout areas are designed for focused activities.

In addition to supporting communal functions, the building is designed with disaster resilience in mind, equipped to serve as a refuge during emergencies. This aspect enhances the facility's value to the community, ensuring that it meets not only daily needs but also provides security in times of crisis.

In summary, the Spirala Community Centre stands out for its integration of sustainable materials, innovative structural approaches, and versatile functional spaces. Its design reflects a commitment to community engagement and resilience, making it a significant addition to the fabric of Coimbra. For a comprehensive exploration of the architectural plans, sections, and design ideas, readers are encouraged to examine the full project 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.
