The redevelopment of the Grade I-listed building involved the creation of new stages, improved acoustics, and new front-of-house facilities, as well as providing additional seating in a completely remodelled auditorium.

The project involved restoring the beautiful glass Floral Hall, raising its roof, and creating a number of spaces that improved the experience for visitors and performers using the Royal Opera House.

Work was undertaken in partnership with Arup, Schal International and Gardiner & Theobald.
