Hi all! I am having a really hard time figuring out how to decorate this wall so that it feels more cozy and lively. I can’t figure out if I should get a tall open bookcase to the left of the fireplace, paint it as an accent wall, add art on either or both sides, or have built in shelves put in. The left and right side are not symmetrical since the right side leads to stairs. The current paint colour is a cool blue grey. Thanks!
