The completion of this new - and totally unnecessary - BBC Wales headquarters building portends the demise of BBC Wales ( just as New Broadcasting House in London heralds the end of the BBC itself).
Probably no one in BBC Wales has ever read C Northcote Parkinson's brilliant book "Parkinson's Law or the Pursuit of Progress". If they had only done so they would have encountered this dictum
"When a company or other organization is finally able to plan and build the perfect building for itself, the building best suited to its needs, that organization is in the throes of petrification and death.
so you know for a fact (please show your working out) that it was totally unnecessary. Companies move all the time due to lots of reasons - tell us why you know best.
