So far, half of these have been sold, for a total value of £750m. The scheme's development manager Nick Candy said that these sales had already covered the construction costs. No expense has been spared on the scheme, which is due for completion in September 2010.

Architect Richard Rogers said: “We seldom get a chance to build something of this quality. The last time was probably the Lloyds Building. Tony Douglas, chief executive of contractor Laing O'Rourke, said: “This project stands for the highest pinnacle of quality.”
