Many of the spaces we share with you are beautifully decorated — choices of chairs, rugs, lighting and accessories have an obvious impact on how a room looks. Certainly, decorating makes an incredible difference on the feeling of a space, but this time we’d like to highlight those spaces that have achieved a high level of interior architecture, going beyond just the basic four walls, floor and ceiling. These five examples, from past pages of Rue, have used the same amount of creativity in the structural elements as the decor that complete their look.
