Milan’s council noted that despite Mr Chipperfield’s outrage, he had been well paid for this work. “It cost €60m, of which €3.6m went to Chipperfield for his design and project management,” it said.

The architect David Chipperfield is at the centre of an extraordinary row over Milan’s new €60m (£44m) Museum of Culture, a building he has designed and now disowned after accusing officials of skimping on flooring materials.

The resulting “floor war” – as locals have dubbed the stand off – has led the British architect, famous for the Neues Museum in Berlin and China’s Liangzhu Culture Museum, to demand that his name be removed from the project.

Mr Chipperfield, whose firm has offices in Milan, Berlin and Shanghai as well as London, told a press conference that “the laying of stone of poor quality” had transformed the building into “a museum of horrors,” and that it amounted to “a pathetic end to 15 years of work”.
