Some years ago I designed some houses for the first phase of what was then Prince Charles’s new architectural experiment at Poundbury on the edge of Dorchester. There were about six different architects involved each being allocated a few houses of known shape and size within Leon Krier’s master-plan. Following a design code we all came up with sketches which were then pinned up as street scenes for discussion and criticism. The individual flights of design bravado were then gently brought to earth to avoid an over rich mix dominated by architectural egos. This thinking was later reflected in the arguments put forward by Allies and Morrison stressing that we should value good, ordinary architecture rather than letting ourselves become obsessed with iconic showpieces.
