Why it is worth attending
Open House Festival is London's citywide architecture and neighbourhood-access festival, opening buildings, civic spaces and guided routes that are normally private or easy to overlook. It is especially valuable for serious city-guide readers because it turns London into a live classroom for housing, faith buildings, livery halls, modern towers, libraries and hidden infrastructure.
What to expect
The 2026 festival is scheduled for 12-20 September. Many visits are free but require advance booking, and popular buildings can sell out quickly. Muslim families should build routes by neighbourhood, keep prayer and meal stops nearby, and avoid trying to cross the whole city between timed entries.
