"The Appropriation of Bazalgette's Legacy" is an exploration of the borough of the City of London Corporation and the two lost rivers that intersect it in the form of sewers, whereby the disruptive potential of water to engage the everyday movement of people in the City is used to form an agenda on civic space. The intervention is based on an overarching language of the everyday developed out of a series of investigative walks and materializes in designs that reuse features of the City in combination with the flow of water to create new moments out of the disruption.
