Refusing to set foot in the colony, the eminent Gothic Revivalist architect William Butterfield resorted to sending extremely detailed architectural drawings and plans of St Paul's Cathedral to Australia.
He even produced life-size drawings of columns, window tracery and other features, to ensure the antipodeans could get nothing wrong.
In the end however, he was defeated by distance, and St Paul's was completed by the Australian firm Reed, Henderson and Smart, and later, in the 1930s, the towers he designed (but were not built at the time) were shafted for a new design by Australian architect John Barr.
