The building, which is understood to have been the work of shamed architect John Poulson, has become synonymous with the worst excesses of Sixties architecture in Newcastle.
But it is now beyond reprieve and has been scheduled for demolition within weeks.
Former RIBA president George Ferguson repeatedly highlighted the building during his tenure at Portland Place, as one of the structures that should be X-listed.
Ferguson said back in 2004: 'Westgate House is a brilliant example of one of those terrible buildings which sticks out like a sore thumb.
'As soon as you leave the central station you see it ruining a beautiful area,' he added.
Ferguson suggested that 'particularly bad buildings' should be qualified as X-listed; a rating that would positively encourage developers to apply to knock them down.
The idea was the inspiration for the Channel 4 show Demolition, which also featured Westgate House.
