CPC Group, headed by Christian Candy, and the developer Qatari Diar said in a joint statement that they had settled their dispute over the £3bn project.
Details were not made clear, but CPC will have no more involvement in the 5.2ha site. The original project, featuring hi-tech homes designed by Lord Rogers, had annoyed the prince. CPC sued the Qataris after the latter pulled the project and replaced it with plans for a more traditional design landscaped by Kim Wilkie (HW, 4 June).
In the statement, Candy apologised to the Qataris for any offence caused by taking court action. He also "apologised unreservedly" to Prince Charles.
Last month, the High Court ruled that the intervention of Prince Charles was "unexpected and unwelcome".
Early conceptual sketches of the new masterplan show buildings arranged in Georgian-like squares surrounding landscaped areas, overlooked by tree-lined roads.
