Open House Festival

Take part

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 would not be possible without our amazing community of volunteers, who help contributors to open up their buildings and run their events. It’s a rewarding experience filled with opportunities to learn about London’s architecture and heritage, and to meet like-minded people.

As an Open House Festival volunteer you will get to know one or more of the amazing sites in the festival programme, meet new people, develop skills in stewarding and enjoy a fun day or evening out in a stunning London location. You will also get priority entry to many buildings across the wider festival programme.

You can find out more about what being an Open House Festival volunteer involves here.

Here’s what some of our volunteers from 2023 thought:

“Volunteering provides a more immersive and satisfying way of experiencing the festival.”

“It’s great to be able to spend a bit more time looking closely and soaking up the atmosphere of a place.”

“Marvellous experience. I’d do it again in a heartbeat.”

“Great fun meeting people and sharing my love of London’s amazing history with them.”
