You're no doubt right to complain if I have massacred your walls, of which I have always been a staunch admirer... But you do remember the origin of my undertaking. You said 'La Roche, when one has a fine collection as you have, you must have a house built which is worthy of it'. And my reply: 'Fine, Jeanneret, make this house for me'. Now, what happened? The completed house was so beautiful that, when I saw it, I exclaimed, 'It's almost a pity to put paintings in it'. Nevertheless, I said How could I do otherwise? Do I not have some obligations to my painters, of whom, indeed, you are one? I asked you for a 'frame for my collection' and you gave me a 'poem in walls'. Which of us was more to blame?Raoul La Roche to Le Courbusier, May 1926, Fondation Le Courbusier (Open University, 1984, p.35).
