Searching for identity: finding the expression of place under ground

Cities are increasingly looking for green solutions to urban development, such as green roofs and vertical green infrastructure, as a response to globalisation and climate change. However, while engineered topsoils are being used to support green infrastructure initiatives, the hidden layers of mineral soil and rock that give landscapes their unique shape are often ignored. This research looks at the potential of subterranean soil conditions to express regional differences and challenge global trends in soil use by engaging with the underground in Aotearoa New Zealand. It finds that the uniqueness and richness of the layers of hidden soil can lead to new ways of understanding place through texture, colour, and structure, which in turn can inform aesthetic decisions and develop authentic regional aesthetics.
