• Open House London returns for 2026.

  • The event runs from 12 to 20 September.

  • Tickets are available from 19 August.

Open House Festival spans theatres, museums and studios. 


London is home to iconic buildings, including 10 Downing Street, BBC Broadcasting House and the BT Tower. If you’ve ever been curious about what’s behind those doors, Open House Festival 2026 is here to help. Running from 12 to 20 September, the event unlocks the capital in a unique way.

Many buildings in London are usually closed to the public. The charity Open City aims to make these spaces accessible and encourages people to explore their city. Visitors can join walking tours, workshops and drop-in sessions taking place across the capital.

Open House Festival’s most popular sites – such as the Prime Minister’s residence – operate via a ballot system. This year, the locations include the return of 10 Downing Street, BBC Broadcasting House and BT Tower. Plus, tours include Barbican Conservatory, Leadenhall Market, The Lloyd’s Building, and Zaha Hadid Foundation archive.

Open House 2026

London Open House Festival Director, Celia Mead, said: “We’re delighted that our 35th edition of London Open House is going stronger than ever. There is a real need for access to places and spaces of all types – wherever you can’t normally get inside – and the result is shared experience, a sense of belonging and even joy. In fact, many visitors tell us that Open House is the highlight of their year and they look forward to finding out what is in the programme as if it were Christmas!”

Previous highlights include 8a Belsize Court Garages, The Round House in Romford, and Tin House in Shepherd’s Bush. Plus, British rapper Stormzy’s #Merky FC HQ in Croydon.

The full Open House Festival 2026 programme opens for bookings on 19 August.
