Within this ArchDaily tag page on rammed earth, a standout emerging project is Henning Larsen's design for El Cambio Academy in Masaka, Uganda, developed with Siimi Design Studio, exemplifying on-site rammed earth production for regenerative educational infrastructure. The 1,280 m² modular campus for 60 children aged 9-16 integrates academic and athletic facilities, starting with a boys' dormitory in phase one, slated for summer 2025 completion. Bricks are fabricated from locally excavated soil, compacted into forms that highlight rammed earth's potential in resource-scarce regions. Practical details include modular construction for rapid assembly, leveraging local labor and zero-transport emissions, ideal for resilience in developing contexts. The technique draws from 4,000-year-old precedents like Sudan's Western Deffufa mud brick tower, proving durability in harsh deserts. Key methods: soil excavation, sieving for optimal grain size, moistening to plastic consistency, and ramming in reusable formwork—scalable for earthship-like self-builds or passive house envelopes. Thermal mass benefits are implicit, stabilizing tropical climates against diurnal extremes, synergizing with passive solar orientation for natural ventilation and daylighting. Insights for practitioners: on-site production cuts costs by 40-50%, enhances community buy-in, and supports circular economy by reusing excavated material. Challenges addressed include bracing for tall walls (up to 20m historically) and rain protection via overhanging roofs. This case advances regenerative design by embedding football training pitches with eco-materials, fostering youth education in sustainability. Compared to UK rarity, Uganda's project shows cultural adaptability, with performance data potential post-2025 for thermal monitoring. Ties to broader trends: integrates with rocket mass heaters via mass walls for cooking heat retention, or greenhouse adjacencies for microclimate control. Actionable steps: soil testing kits for viability, pneumatic tools for efficiency, lime stabilization for wet areas. Durability rivals ancient structures, with low maintenance if detailed properly. This signal-rich example equips builders with specifics for climate-adaptive, low-tech solutions in global south resilience projects.
