Open House Festival 12th - 20th 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.
