Mr Orozco used to lead a nomadic life, but now that his six-year-old son has started school, he's settled into working on the lower ground floor of his New York home, a red brick Greenwich Village townhouse built in 1845. Mr Orozco prefers to see the space as a modest "operating center". With contemporary art, mind invariably wins over matter. "For me, it has always been important not to have a studio, not to have a permanent assistant, not to have secretaries," he explains as he leans back, relaxing into his chair.
