The state of chaos at what is now called The Prince of Wales's School of Architecture and the Building Arts (POWSOABA! ) reached new depths last week when Hugh Petter, head of the foundation course and a stalwart of the whole place, handed in his resignation. This was his response to the abrupt departure of Richard Hodges as director of the school, allegedly by mutual consent. At the same time, former director Richard John was to ld that from now on he should sign the visitor's book whenever he attends. The official statement about Hodges implied that he had volunteered to leave after just 18 months' 'secondment'. In fact he considered his work far from finished, but felt obliged to go, Astragal understands, because of internal documents he discovered, telling lies about him. Wednesday morning staff meetings - or 'Listen with Mother', as new head of school Adrian Gale likes to call them - are in danger of turning into weekly wakes.
