Seeing the Whitby Abbey scheme by Stanton Williams in the AJ reminds me of a unique double. Paul Williams, who trained in interiors, has recently qualified as an architect in that most difficult of ways:
portfolio presentation and a gruelling interview. He is already an honorary fellow of the RIBA; the point about 'hons' is that they are only awarded to people ineligible to join the institutes in theory he could now style himself Paul Williams RIBA Hon FRIBA. What is the precedent here? Perhaps the College of Heralds could help.
