I have a mild obsession with white painted hardwood floors. (Mild meaning greater than my obsession with checking that the iron is shut off, but less than my obsession with washing my hands). Rooms with white painted floors are bright, clean, airy, and serene. I imagine the owners of these spaces drink herbal tea, and wear a lot of linen clothing.
With white floors, I think the rest of the decor has to be a bit worn, with a shabby-chic, cottagey vibe, and some colour or texture thrown in, otherwise it can feel a bit sterile, or like you’re living in a white padded cell. Which is not really that inviting. Whenever guests came over you’d have to hand them a straight-jacket and say: “Make yourself at home!” Straight-jackets put a real damper on an evening…although they don’t look bad with linen pants.
