A deep understanding of the existing rail and heritage infrastructure was required for the upgrade. It retained and conserved significant heritage elements, while meeting accepted sustainability and visitor safety requirements. The new facilities were composed with recyclable and former era materials, including metal cladding, in situ and precast concrete, glass and steelwork. An innovative under-floor hydronic heating and cooling installation supports ventilation throughout, and a 100,000 litre rainwater tank supplies water to the museum.
