Developer Irvine Sellar gave a “cast iron” guarantee that his £350m plan for the skyscraper that would eventually be known as The Shard would not be altered or “dumbed down”.

Sellar also insisted he would not sell the site for the tower on winning planning permission or on completion and said the building could achieve rents of £50/sq ft.

Sellar completed The Shard in July 2012 with the original design intact and it remains the tallest building in both the UK and mainland Europe.
