"When a job is handed to me I tuck it away in my memory, not allowing myself to make any sketches for months on end. That’s the way the human head is made; it has a certain independence. It is a box into which you can toss the elements of a problem any way, and then leave it to ‘float’, to ‘simmer’, to ‘ferment’. Then one fine day there comes a spontaneous movement from within, a catch is sprung; you take a pencil, a charcoal, some coloured crayons … . . and you give birth on the sheet of paper. The idea comes out… . it is born."
— Le Corbusier
