“It reminds us, each year, that people genuinely like what we do. We particularly enjoy the diversity of the people who come each year.”

— Open House Festival 2023 contributor

Open House Festival is a London-wide festival that opens up and celebrates the city’s architecture and neighbourhoods, with open days and events taking place across all 33 London boroughs. The festival is a chance to explore the remarkable buildings and landscapes of the capital, and an opportunity for individuals, communities and organisations to tell their stories.

As a festival contributor you can run an open day at a building or outdoor space, put on a walking or cycling tour, or organise an event such as a film night, children’s activity workshop or exhibition.

You can find all the information you need to become a festival contributor here.
