In our suburban homes, we have been experimenting with the concepts of indoor/outdoor living and how to create a socially cohesive and flowing home. How does that apart to a large vertical urban home? A unifying white concrete staircase acts as the spine, connecting all levels, wrapped in glass. A tall thin lightwell blurs the line between inside and outside, bathing the stair in light. The building steps back and in as it rises, with floor-to-ceiling sliding doors systems giving way to generous terraces that act as outdoor rooms. A warm and relaxed palette brings a feeling of easy luxury to the whole home with silver travertine, wide oak floors, creamy leather wall panels and oiled oak cabinets.
