Brunel Museum, Rotherhithe, London

The conversion of the entrance caisson to Brune's Thames Tunnel, the first tunnel under a navigable river, into an underground performance venue. The London Overground line runs through the tunnel and beneath a concrete slab at the base of the caisson. Transport for London required detailed justification of Brunel's construction for the new staircase, the entrance that was cut through the four-foot thick brick walls, and that the reduction in levels externally for the entrance ramp would not affect the stability of the brick shaft. 

Completed 2016.
