Working closely with Network Rail, Galliford Try and Arcadis, we have proposed a comprehensive replacement of the roof covering with a singly ply ETFE glazing system. It is an approach which reduces the loads on the existing structural trusses so as to minimise any further sagging and which provides movement tolerance to allow the existing structure to ‘breathe’. Careful assessment and re-creation of the existing glazing bar modules provides a visual aesthetic which is fully in keeping with the original design intent, whilst using modern materials to overcome technical difficulty is completely in keeping with the design ethos of the original Victorian designers.
Listed Building Approval has been granted with construction work scheduled to start in summer 2016. Speed of erection of the ETFE system is offering significant reductions in the programmed construction period, minimising disruption to ongoing activities below.
