this cricket pavilion for a stadium in rwanda comprises three vaults, which have been produced on site using local materials and labor. the roofline of the vaults has been designed to mimic the parabolic geometry of a bouncing ball, while evoking the country’s undulating topography. the masonry vaults are completely in compression, allowing the use of a simply layered thin shell composite of low strength tiles.

the project has been undertaken by light earth designs for the rwanda cricket stadium foundation over a five-year period. the initiative explores how rwanda can transition from an agriculture-based economy to development using local home grown labor intensive construction techniques, thereby avoiding imports, lowering carbon, and building skills and economies.

produced on site by local workers, trained by an expert mason, the tiles are hydraulically pressed with a small addition of cement and do not require firing. they are placed on top of a temporary timber skeleton, with a geogrid — developed by research in architecture and engineering at cambridge university — added to give some seismic protection. the shells are waterproofed before being topped with locally sourced broken granite that adds both weight and stability.

concrete plinths are inserted into the vaults, providing space for the more enclosed functions: the service areas, the changing rooms, an office, and a restaurant. above, the open mezzanines — a bar and a clubhouse — enjoy panoramic views over the pitch and the wetland valley beyond. low carbon bricks are used to delineate space, while allowing light and air to circulate across the site.

ensuring that a maximum of waste material goes into primary production, the plywood rectangles used to press the tiles are reused as countertops, while timber and plywood from the vault guidework is made into joinery and doors. see designboom’s previous coverage of the project here, and take a look at our comprehensive archive of sports stadiums from around the world.
