I've always found old floors painted white gives a fresh, clean look to a space. It's also a great to add rugs to white floors, they really pop off the white and can provide a burst of colour. I've always loved the spread in Elle Decor many years ago where American designer, Darryl Carter showed his summer place with painted white floors. Here are a few images from that. His book New Traditional, is still one of my favourites!
BEFORE & AFTER: LANDING & STAIRS
In my house I have a large landing between the second and third floors. I, of course, painted everything white. It's not how it looked before! Here it is in its original state with wallpaper and brown floors. The old plaster walls and ceilings were all in very rough shape (not to mention the layers of wallpaper in some areas), so new drywall throughout was in order. Also since all new electrical was being done in the house they had to put a lot of holes in the walls for wires and cables. These before shots are of the landing and looking into the bedroom.
Now here it is once we had new drywall painted and a coat of white paint on the floors.
And finally...with furniture, rugs and art on the walls!
