DescriptionFollowing the Jubilee line extension works there was a requirement to develop the existing Palace subway network. This included the formation of an enlarged tunnel running underneath Big Ben to Portcullis House. The original 150 year old access tunnel, running approximately 1m beneath the main road, rendered unsafe from the effects of high volumes of traffic.
Stonewest utilised surplus materials previously used on other aspects of the Palace and which had been in long term outdoor storage. These salvaged Ketton stones were cleaned, re-worked and then assembled, like pieces from a large jigsaw, to form the basis of the new vaulted ceiling. A delicate operational process followed.
