T8 - Urban underground development & innovative uses of underground spaces

Urban underground development is increasingly seen as a solution to growing cities facing limited surface space. By utilising the underground environment, cities can create multi-functional spaces that support urban growth, enhance sustainability, provide secure storage, and improve quality of life, while reducing congestion and minimising the impact on the natural landscape.
