Jan and Juliette have little color in their interior. Variation in color is in the ceilings and the walls they left raw ; they are only chemically cleaned . Apart from a wall in the bedroom which has been painted grey. Variation is in the pipes, which are left in sight, giving the room an industrial look. ‘The idea that the bathroom is part of our bedroom has to do with the loft idea that we had at this immense building. We did not want to make separate rooms. Everything nice and open. “
