In a modern bedroom, small spaces are often optimized by adding mirrors. There is less room for furniture in modern design, like in this space that replaced bulky night stands with stacks of books, so keep the lines clean by adding a reflective surface such as a floor length mirror which instantly helps to add dimension to the room.
Another trick in this room to make it look larger is the use of the color white. There is a lot of white in the bed linens and each art print placed above the bed has a stark white background. Instead of adding a bed that has a large platform or bulky dressers, this room focuses on the wide space and makes the most of it. A walk-in closet also helps the room keep from being cluttered.
