High Contrast: The question of the facade was a big one: How to unite the house, with its quaint old villa, and the squat, square, ugly minimart add-on built flush against it? Instead of trying to minimize the discrepancy, the architects emphasized it. They kept the old-fashioned facade intact and painted it graphite gray using RAL color 7024, made by Brillux, and then covered the "box" next door in plain, light-colored larch.
