not sure I like that much white.but the architectural notion of using one color to unify the room.it also allows the use of a day bed look without jarring the living space too much. almost creates a reading nook in a small space!
I like the way they did this harth and the color painted behind the stove. I also like the wood beams framing the stove in. Maybe have similar framing and the make a gate around the stove out of the same wood.
