Amid much controversy, the 2022 World Cup has begun and the action has now moved onto the football pitches inside the many newly built stadiums in Qatar. But how are these stadiums turned from architectural sketches into real buildings?
For this week's episode we delve back far into our archive to hear from Paul Shepherd from the University of Bath, an expert in building football stadiums such as the famous Emirates stadium in London. In this interview, first recorded back in 2007, he tells us about what kind of things are important in building a stadium, how maths is an integral part of the design process, and why his work required him to listen to Belgian techno.
