London Open House Festival

Throughout London

A behind-the-scenes look at London’s most remarkable buildings

From 6th to 17th September 2024

London’s annual Open House Festival is a unique opportunity to explore some of the capital city’s most fascinating buildings.

With open days and special tours across two weekends in September, it unlocks the doors to a diverse range of remarkable homes, iconic buildings, and hidden gems visitors wouldn’t usually get to see.

From grand government buildings to a Passivhaus primary school, modernist apartment blocks to a striking Sikh temple, it’s a rare chance to get a glimpse behind the scenes of some of London’s most intriguing architecture.

Spanning London’s 33 boroughs, you can explore cutting-edge carbon-neutral homes, industrial grandeur, and elegant gardens, all of which are usually hidden behind closed doors. It’s a fantastic opportunity to learn about the capital’s unique neighbourhoods from the inside.

Visitors can join dozens of walking tours or workshops to learn more about London’s built environment too; you could discover hidden green spaces, waterways, and underground secrets, uncover London’s lost architecture, or marvel at handsome new developments.

If you’re inquisitive about architecture or just curious to see behind closed doors, the Open House Festival promises a delightful day out. But book ahead—access to some of the most popular buildings is by ballot.
