Yes, as others have said this used to be a Hounslow Council building, I recall spending a day or two there when I first started with the authority in 2001 for training of one kind or another. I wasn't aware of any plans at the time but in hindsight it was pretty obvious that the Council was looking to dispose of it/redevelop it.More information available, including the planning committee report to what was then the Isleworth & Brentford Area Forum, at the link below :https://democraticservices.hounslow.gov.uk/mgAi.aspx?ID=7736
