In 1992, we were one of five practices commissioned to compile reports on the stations in the LUL network. Most were not listed, but all had significant historic value, and our reports and proposals for conservation policies were intended to inform any future work on them. We identified their architects, builders, history, any changes made to them and features to be conserved.
These records have been published as individual booklets for each station and are now part of the Underground's archive. Margo Sagov, Christophe Egret and Anthony Wise shared the task.
