The programme kicks off on 12th September with a behind‑the‑scenes guided tour of the Civic Centre at Hillingdon Museum and Archives Service, Uxbridge, running from 11am to midday. Attendees will admire the building’s striking architecture and its art collection.

Manor Farm in Ruislip opens its Tudor Manor House and medieval Great Barn from 12th to 13th September, 10 am‑4 pm, with the Great Barn available for a special viewing between 1 pm and 4 pm on 13th September.

Throughout the nine‑day festival, families, history enthusiasts and local residents are encouraged to discover Hillingdon’s hidden treasures, supporting community engagement with the borough’s cultural heritage.

Cllr Wayne Bridges, Hillingdon Council’s Cabinet Member for Residents Services, said: “Hillingdon is home to a range of remarkable buildings. Some have impressive architecture, others have intriguing histories linked to the Second World War, with all providing an eye-opening glimpse of life in the borough in days gone by.

“For this year’s Open House Festival, residents will have a fantastic opportunity to explore some of our most distinctive heritage sites, including those areas that are rarely open to the public. It’s a chance to discover more about the borough’s rich history and see some of these fascinating buildings from a different perspective. 

“For fans of municipal architecture, we’ve even included a tour of our very own Civic Centre, a striking Grade II listed building of British ‘neo-vernacular’ design.”
