Do you remember the Arup Associates competition winner for the redevelopment of Paternoster Square, masterminded by Sir Philip Dowson and Peter Foggo? If so you will also remember the rival scheme, designed by John Simpson, illustrated with Carl Laubin choirboys, and presented as the Prince Charles alternative. Arup's was eventually ousted, leading to a long and complicated saga of ownership and redesign. In the various subsequent schemes, Simpson always managed to keep some presence; in the current scheme, masterplanned by Sir William Whitfield, his was attached to a replacement building opposite the north transept of St Paul's. There was just one little problem: finance group Charterhouse, owner of the existing building, had never agreed to any such scheme. The company is now reconciled to a new building - but not one produced by John Simpson. Instead the design will be undertaken by . . . Sir William Whitfield! Now Simpson will know what Dowson and Foggo felt like.
