Wild Site explores the ephemeral by-products of an ever changing city: gaps between buildings, brownfields, intermediate and residual spaces, “wild sites”. Five conversations with researchers from the fields of biology, geology, climatology, botany, landscape architecture, urbanism, and architecture are accompanied by a photo series by Zara Pfeifer. Edited by das BAU: Eva Herunter, Katharina Hummer and Julia Obleitner
