hey, there are some ways that you can make a small room bigger. First, allow space in the middle area and make sure no any furniture is on the pathways. Then choose the color of you paint. Try combination of cream color and ice blue. And lastly, the lighting is also important. Make sure there's a natural light coming inside the room. You can also put up a decorative lamp on the side. And another tip, is placing big mirrors on the wall that can create illusion of depth.
hope this helps
