In carrying out the building work, a policy of ‘conservative repair' has been followed which means ‘retaining genuine historic fabric and avoiding misleading restoration, so that future generations can interpret the significance for themselves in their own way, based on the physical evidence’. The work has been carried out by Fullers (Phase 1 – the Auditorium) and William Anelay (Phase 2 – the Front of House) under the careful direction of Tim Ronalds Architects, EC Harris, Bristow Johnson, Cambridge Architectural Research, Max Fordham, All Clear Designs, Ramboll UK, Carr and Angier and Wilton's staff.
