The cross-section is slightly more than a semi-circle so that the bottom of the hut curves inwards slightly. The exterior is formed from curved corrugated steel sheets 10 feet 6 inches (320 cm) by 2 feet 2 inches (66 cm), laid with a two-corrugation lap at the side and a 6-inch (15 cm) overlap at the ends. Three sheets cover the arc of the hut.
