This 3,400-acre offgrid campus in Rwanda 🇷🇼 was built by 2,500 people from the earth beneath it. Most people think building with earth means small, temporary, or weak. This is a 2-storey, 69-building campus. Built with rammed earth and earth blocks made from soil dug on site, strengthened to last and resist earthquakes. Here is what that looks like: • No artificial lighting during the day • Thick walls that regulate temperature • Mostly naturally ventilated spaces • Runs entirely on solar, producing 1.5MW of power • Wastewater is treated and reused for irrigation But the architecture goes beyond performance. • 90% of the workforce was local • 96% of materials were sourced within Rwanda • 90% of the budget stayed within 500 miles of the site • Stone from local quarries reduced concrete use. • Roofs were built with timber and terracotta tiles fired using agricultural waste. This is not just sustainable design. It is economic design. It is design that works with nature. It is design shaped by people and place. Architecture that builds with people, not just for them. Local materials are not a limitation. They scale. They perform. They work. Project: Rwanda Institute for Conservation Agriculture (RICA) 📍 Bugesera District, Rwanda Architects: MASS Design Group
