# USINA: Collective Construction as a Political Practice in Brazil How participatory design transforms social housing and empowers communities. - **Source:** [ArchDaily Global](https://brifing.si/source/b856ce4a-b51b-4705-954b-40620e034caa) - **Published:** 2026-09-12 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/7ea4d8a1-c679-4051-b41c-759f6fcec783 ## The Renaissance Divide in Construction The separation between design and construction began with the Renaissance, exemplified by Brunelleschi's dome in Florence. This divide grew with industrialization, fragmenting roles among designers, builders, and financiers. While efficient for large-scale projects, it centralized knowledge and decision-making, distancing residents from the creation of their own spaces. ## USINA's Emergence in Redemocratization Founded in São Paulo during Brazil's 1990s redemocratization, USINA united architects, engineers, and social scientists. They aimed to integrate technical assistance with social movements, focusing on housing production. This period saw a resurgence of collective action, with USINA pioneering participatory models that challenged traditional construction hierarchies. ## Mutirões: Beyond Labor Participation USINA's mutirões (collective self-builds) transform construction sites into spaces of learning and decision-making. Families contribute on weekends, handling everything from bricklaying to childcare. Crucially, participation isn't just labor—residents collectively discuss materials, costs, and designs, democratizing technical knowledge typically reserved for specialists. ## Architect as Facilitator, Not Authority USINA redefines architectural practice, shifting from finalized designs to ongoing negotiation. Technical teams translate complex information into accessible discussions, ensuring knowledge circulates beyond experts. This approach challenges professional boundaries while maintaining construction quality—over 5,000 housing units built prove its viability. ## COPROMO: Scaling Collective Construction The COPROMO project in Osasco defies assumptions about self-build scale—1,000 apartments across 50 buildings, constructed over eight years. Using self-supporting ceramic blocks eliminated need for structural frames, enabling inexperienced participants to build safely. This demonstrates mutirões can deliver urban-scale housing without corporate developers. ## Paulo Freire's Technological Hybridity At Mutirão Paulo Freire, USINA paired multi-level steel structures with basic techniques, challenging prejudices about self-build sophistication. Appropriating high-cost technologies for social housing serves symbolic and practical goals: improving quality, accelerating completion, and reclaiming tools typically reserved for elite projects. ## Financial and Logistical Innovation USINA's projects navigate complex financing and infrastructure challenges comparable to conventional developments. Their model proves self-managed sites can handle scale while maintaining technical rigor. The eight-year COPROMO timeline shows how incremental progress accommodates participants' limited construction time without compromising outcomes. ## Beyond Housing: Community Infrastructure USINA's impact extends beyond dwellings—they've built schools, daycare centers, and community spaces. These facilities emerge from the same participatory process, ensuring they meet actual needs. The amphitheater construction photo captures how cultural spaces become sites of collective identity formation through shared labor. ## A Blueprint for Housing Justice USINA's three-decade legacy demonstrates how construction can be both technically sound and politically transformative. By making building sites spaces of learning and decision-making, they challenge global housing inequities. Their work offers actionable models for democratizing urban development worldwide. ## Sources covering this story - https://www.archdaily.com/1184105/building-as-political-practice-usina-and-the-legacy-of-collective-construction-in-brazil — --- _Summary written by Brifing from the original reporting.
