Yesterday's post about Willesden Green Library Centre reminds me that I meant to do something on its relation to Brent Civic Centre. An aspect that hasn't come into the debate is that the two are related for emergency planning purposes.
Were there to be some kind of freak accident making the usual parts of the Civic Centre unusable, there would need to be a Council office from which the Council could still operate its emergency roles. This would have to be physically separate from the Civic Centre, in case the accident was something like a plane crashing on the Centre. Willesden Library Centre (in the Council offices bit) can fulfil this role.
