Open House Festival is a two week celebration of London’s housing, architecture and neighbourhoods. Open House is an annual festival celebrating the architecture and urban landscape of London. It is staged by the charity Open City which campaigns to make London a more accessible, equitable and open city. During the Open House festival, many buildings considered to be of architectural significance open their doors for free public tours.

The 2019 event featured over 800 buildings, neighbourhood walks, architects’ talks, cycle tours, and more. Well-known buildings not usually open to the public which were open on Open House weekend in 2005, for example, included Marlborough House, Lancaster House, Mansion House, the Foreign and Commonwealth Office, and Horse Guards. In a typical year, Open House Weekend attracts around 250,000 people.

Outside of the Open House festival, Open City organises other projects including year-round tours, lectures and educational events for children and young people. Expect to see Battersea Power Station and other Nine Elms buildings participating this year.
