A registered charity, the Twentieth Century Society is the national amenity Society responsible for the study and protection of 20th and 21st century architecture and design. The Society was founded in 1979, as a direct response to growing interest in C20th architecture and has a formal role in the UK planning process.


Our focus is on preservation and education.  We campaign to protect the buildings and design that characterise C20th Britain. Today, we are involved in a number of important campaigns, all of which involve our experts, members, volunteers and supporters. In addition, we undertake casework related to specific buildings facing demolition or major change, navigating the opportunities and risks from retrofit and adapting to climate change and applying for buildings to be listed.


The C20 Society raises over £300,000 annually to support the Society’s mission through a range of activities including: individual and corporate membership, donations, a programme of events including guided tours, international trips and lectures, and the publication and sale of books. The income from these activities is used to fund our campaigns, casework and running costs.
