 Yeah, first of all, color is key. Painting your walls white, cream, pastel, or even a cool color, something that's just kind of tinged with a blue or a green tint, that's going to create the illusion of having more space because it reflects the light around. White or lighter colors on the walls does lift up the ceiling and it brings your eyes up, and that can make you feel like you're in a larger room to begin with.
