Open House London 2023

Open House is a festival celebrating London's architecture and neighbourhoods. For two weekends (September 9-10 and 16-17) buildings open to the public so you can get inside and explore some of London's most impressive buildings, as well as some of its best kept secrets. 

It's a festival that celebrates our curiosity for what happens inside the buildings that we walk past every day; a festival that works to give all Londoners the chance to learn from this city’s architecture and the people behind its architecture.

A community of people who live, work, volunteer or care for these buildings contribute to the festival by opening up their building to the public for a period during the two weeks.

You can visit areas of London you’ve never been to before or explore the parts you know really well so that you can finally get inside the buildings you’ve seen from the outside so often.
