This book is about the architecture and design of broadcasting in the 1920s and 1930s, examining the buildings which the BBC occupied in its founding decades, with a particular focus on Broadcasting House in London. It argues that these environments were as constitutive of the Corporation's identity as the programmes and people that they housed. Borrowing from the architectural writer Christopher Hussey's characterisation of Broadcasting House as a 'palace of the ether' Elizabeth Darling asks how the immaterial medium of the broadcast was given material and spatial form by the BBC, and the engineers, architects and designers whom they commissioned. The book traces the development of the BBC both technologically and organisationally, and the changing demands it had of the spaces which accommodated it. It shows how associational networks and personal affiliations affected who was commissioned to work on what became Broadcasting House and offers a detailed account of the work of Val Myer, who designed the exterior and shell of the new building, and the team of architects who designed the studio interiors (Serge Chermayeff, Wells Coates, Edward Maufe, Raymond McGrathand Dorothy Warren). In documenting the design of Broadcasting House, and the responses to it, The Palace of the Ether offers new insights into British architectural culture at a pivotal moment in the profession's history.
