Wilton’s Music Hall is the only mid-Victorian Music Hall that survives, anywhere. It is listed at Grade II*. For everyone who has been there the atmosphere of the Hall hidden behind dilapidated houses is unforgettable. By 2006, the Hall and row of houses were extremely fragile and in a state of considerable disrepair. Our strategy was to “do no more than essential.” The design team worked closely with Frances Mayhew, Wilton’s inspirational director and her team to design the necessary interventions in a way that ensured they did not compromise the building's existing character. It took nine years to raise the funds and complete the project, but these words pretty much describe what we have done. Wilton's now supports a wide range of activities, from new work in the creative arts to school workshops and family weekends with the local community. The building project has ensured the continuity and extension of that programme by making the building safer and bringing previously inaccessible areas into use for everyone. The project has preserved Wilton’s as “London's hidden gem.”
