Speirs + Major were invited to join architects Allies and Morrison to relight this important performance venue, the only post-war building to be listed Grade I.

The scheme required extensive research into the original 1951 lighting philosophy and a clear understanding of how the client wanted to use the building in the future – a careful balance between the desire to respect the original listed building and the need for optimum flexibility.

The new lighting concept builds on the precedent of the existing scheme to ensure authenticity and a respect for the architecture. At the same time, it exploits the opportunities presented by the alterations around the stage area and the use of new technologies to create a more flexible, exciting and sustainable solution.

The illumination of external areas extends the presence of the building and underscores the cultural values of the South Bank. It also provides a safe and secure environment without overlighting the local area.

The interior public space is treated as a lit landscape. Particular attention was paid to how light could reveal the diagram of the building, the so-called ‘egg in a box’, and also assist with wayfinding. The external image of the building is derived from the internal lighting. To heighten the contrast with the warm interior lighting, all external built elements are treated with a cool white light. Wallwashing to the auditorium and cores also gives greater clarity to the space when viewed from the outside.

Improved lighting control now balances levels of illumination by day and night, and also allows more variability for multifunctional needs. More efficient fittings and high efficacy sources help to reduce running costs and create a more sustainable solution.
