This symposium addresses the potential and challenges of stone re-use in London, focusing on two projects that re-use large granite stones from the historic Bazalgette Thames river wall, made available as part of the Thames Tideway Tunnel works. 

The two projects have been recently completed. One is a permanent re-use of the stones in the Becontree Estate by Nimtim Architects and the other, From the Thames to Eternity, is a temporary re-use at sites across the City of London, by Matthew Barnett Howland (CSK Architects and The Bartlett School of Architecture) and Oliver Wilton (The Bartlett School of Architecture) and featured in the London Design Festival.

The symposium discusses and contextualises the work, considering the history and geology of the stones, their removal from the Thames river wall as part of the Thames Tideway Tunnel project, and the broader challenges and opportunities of stone re-use today.

This symposium is organised by Clarisse Tavin, Matthew Barnet and Oliver Wilton. This event is organised in partnership with the City of London Corporation.
