You will also want to keep a close eye on the color palette of the room. A common feature of open floor plans is that they tend to stay on the bright, neutral side of the spectrum of the design. A small open space is no exception. In fact, in small spaces, it is even more important to keep the space clear and neutral. Lighter colors help keep spaces open and free.
In addition, keeping the area well lit will help it feel more open because the dark spaces usually feel automatically closed. You might consider items like large windows or skylights. These will keep the natural light flowing in the space. If it’s not an option, other lighting features such as recessed lighting, pendant lighting and even casual chandelier designs can keep the space well lit.
