If you have ever walked past a building in Richmond upon Thames and wondered what lies behind the door, Open House Festival is your chance to find out. Running from Friday, 12 September to Saturday, 20 September, the annual London-wide celebration offers free access to some of the borough's most fascinating landmarks, historic buildings and creative spaces.
More than 20 venues across Richmond upon Thames are taking part this year, covering everything from architectural gems and heritage sites to spaces that explore the borough's natural environment and creative life. No tickets are required for most events — it is the kind of cultural weekend that costs nothing but rewards curiosity.
The festival is a good opportunity for residents who have lived in the area for years to see familiar streets and institutions with fresh eyes, as well as for newer arrivals still getting to know the neighbourhood. Events vary in format — some are simple open doors, others include guided tours or talks.
Full details of participating venues and any booking requirements are listed on the Richmond Council Open House Festival page. The programme is worth checking early, as some popular spots fill up quickly.
