As a single person, you're the master of your own castle. When your castle consists of two rooms keeping the decor simple offers a more organized, clutter-free space. Good interior space planning can make a small space appear more open, spacious and airy. By choosing the right colors, textures, furniture and window treatments, you can create a comfortable space. Small rooms are hard enough, but add lots of angles to work around it might seem impossible. The paint color you choose and how you use it plays a major part in creating a relaxing and appealing space. A few other components, such as furniture, accessories and lighting help to make a small, choppy space feel spacious and relaxing.
