OK, this is two rooms, but I couldn't choose one since they are both amazing! These are from French interior designer Isabelle Heureux, who believes in mixing materials and in designing according to Feng Shui principles. Look at the reuse of materials in the kitchen cabinets and island. The raw floors, walls and ceilings are amazing (not to mention cost-efficient) and lighting and furniture is kept simple. And I love the way the sofas are placed for great conversation.
