Look around your home and find opportunities for Feature Walls and they can transform a space. In this image the space through the arch (?) has been painted black. Make sure you have plenty of natural light coming in to the room if you are going for a darker tone and make sure the artificial light is good too. That then forms the perfect backdrop for a great painting or in this case some gold angel wings from Marina ( I bought them in Silver too).
The effect gives length and depth to a space as well as adding to the flow through the house.
