Open House Festival 2026
12-20 September
Open House Festival is a London-wide festival that opens up and celebrates the city’s built environment. Every year, buildings and other sites across all 33 London boroughs open to the public, so that Londoners can explore them for free.
The 2026 festival will take place 12-20 September and will be the 35th edition. You can get involved by attending open days and events during the festival, opening a building or running an event yourself, or helping us to make the festival happen by volunteering your time.
“I always loved London. Open House just makes me discover new reasons to love it.”
