Quote from Bit of Blur, the autobiography:

“I’d dealt with builders and architects before, in London. Architects are a discrete genus of the species of Homo sapiens. To be a successful architect requires a similar mesmeric charm that is the bread and butter of the film director, the television evangelist, the hypnotist and the Pied Piper of Hamelin. They arrive with their little satchels and their propelling pencils. Everything about them says calm; from the crisp white sheets of paper they use to cast their spells; to their supernatural patience. They retreat, taking your dreams with them in that little satchel, and return with goblins, pixies and demigods who turn your house into dust.”
