The ambitious £27m restoration of Alexandra Palace’s east wing, which originally launched the world’s first regular TV service, will be carried out by construction firm Willmott Dixon.

Alexandra Palace chiefs hope to showcase the former BBC studios as an immersive birth-of-TV experience by 2018; the Victorian theatre will once again be a performance venue; and the east court entrance hall will recreate a sense of its original 1870s grandeur.

The construction firm will be tasked with the delicate task of removing asbestos, now banned, but once used for sound and fire-proofing.

The Heritage Lottery Fund is contributing nearly £19m, and Haringey Council nearly £7m.

“Almost half of Alexandra Palace is still inaccessible to the public. This project will help put that right,” said Louise Stewart, chief executive of Alexandra Park and Palace.

Alexandra Park and Palace Charitable Trust need to raise the final £1m to complete the project. To donate or find out how to get involved, visit memory.alexandrapalace.com
