Twentieth Century Society
The Twentieth Century Society, founded in 1979 as The Thirties Society, is a British charity that campaigns for the preservation of architectural heritage from 1914 onwards. It is formally recognised as one of the National Amenity Societies, and as such is a statutory consultee on alterations to listed buildings within its period of interest.
History
The catalyst to form the society was the proposal to replace Lloyd's of London's Classical-style 1920s headquarters with a new modernist Richard Rogers building. Marcus Binney, John Harris and Simon Jenkins felt that the existing building "represented a whole body of important architecture of the period that deserved more sympathetic assessment". Ultimately the façade of the 1920s building was retained and received a Grade II listing in 1977. It was incorporated into Rogers' 1986 design.Established in December 1979, the Thirties Society, as it was initially called, had offices at 21 Cambridge Street, London. Its organisation was modelled on the Georgian Group and the Victorian Society, and its initial intention was to preserve architecture from the 1930s,
by calling for "statutory protection from the Department of the Environment for the protection of important buildings and interiors". Speaking of the need for the society, Jenkins, the vice-chairman, said "It's easier to find examples of architecture from the 1890s than the 1930s, and although there are buildings which I find absolutely hideous, there are architectural reasons why they should be preserved." In 1992, a spokesperson for English Heritage said, "We have found the Thirties Society proposals are usually well supported. It has been very influential in saving some of the best twentieth-century buildings."

Name
There was a debate over the society's name. The Inter-War Society was considered too martial and it was joked that The Twenties and Thirties Society sounded too much like a dating service. The name The Thirties Society was eventually settled on. The name was changed to The Twentieth Century Society in 1992, about which Stamp said, "Much as I like the very English anomaly of a body called The Thirties Society defending buildings of the 1950s, the fact is that our name obscures our aims. We defend buildings put up as late as the 1970s."Manchester branch
In 1982, a Manchester branch of the society was formed, with a focus on the Grosvenor Picture Palace on All Saints Street, which was under threat of demolition.Other activities
The society held its first conference, on the seventies, in 1999.The society published a journal between 1981 and 2018; initially entitled The Thirties Society Journal it became Twentieth Century Architecture from 1994.
In 2019, to mark the society's 40th anniversary, they curated a list of 40 Buildings Saved, a collection of 40 "buildings which would not have survived without our intervention" including Jubilee Pool in Penzance, Plymouth's Civic Centre and St. Augustine in Manchester.
The Risk List
In 1998, the society released a Buildings at Risk report, which included Pimlico School, Romney House and Simpson's Building. Of the report, Bronwen Edwards, a C20 caseworker, said, "What is indisputable is these buildings are a unique record of social, economic and architectural history – a vivid reminder of the way people lived, worked and played through the century."Starting in 2015, the society has published The Risk List every two years, which highlights ten buildings that the society believes are "in danger of either substantial alteration or demolition".
