Open House Festival is a London-wide festival that opens up and celebrates the city’s architecture, special sites and neighbourhoods, with open days and events taking place across all 33 London boroughs.

Open House Festival 2025 will take place between 13 - 21 September when you can explore Bromley’s architectural gems and fascinating spaces.

Originally introduced as a weekend long opportunity for visitors to enjoy places of architectural interest not usually open to the public, Open House Festival has now expanded to a week-long celebration of architecture and open spaces across London. Each day, participating venues throw open their doors and welcome everyone free of charge to curious visitors keen to explore and appreciate places of interest often hidden from the public.

Open House Festival 2024 saw an expanded Bromley showcase, with a former rockstar changing room, a theatre converted from a stable, and a history tour of Petts Wood joining the venue list.

Bromley’s 2025 Festival programme will be announced this summer.
