When you decide to finish your basement, there are a lot of things you take into consideration. For starters, we have wall colors, flooring, lighting, and not to forget the overall decor. Generally, window treatments may be the last thing on your mind, until you stop and realize you have these tiny windows you need to somehow cover up.
The typical basement window is the same width as your regular window, but significantly shorter. This not only results in a minimal amount of light being let in, but generally the issue that anyone outside can peek down into your space quite easily. Therefore, you are left looking for a covering that will provide some privacy, but not block out a lot of light.
The go to treatment in basements is most typically a cellular or pleated shade when looking from a functional perspective. The main reason being that they have a small mounting head rail. The head rail for these shades can be mounted on pretty much any window, and close tight and compact with minimal stacking if you want to have the shade open. The other benefit to cellular or pleated shades is that they are available in light filtering materials and fabrics , which will give you privacy, but still let the light stream through. They come in a wide variety of colors and textures which will allow you to add a pop of color or design to the decor in the room. If anyone may be sleeping in the room, they are also available in a black out option as well.
From a decorative perspective, you can add drapes or curtains to make the windows appear a little larger than they are. Adding a curtain panel to each side of the window that falls below the sill, or even to the floor will give the window an illusion of being more open. It will give an impression that both the window and the wall are larger than they are, while giving you the chance to dress the room up a little more.
They key to basement decorating is always to remember that less is more. The space is generally small, the ceilings low, and the windows short. The simpler you decorate, the bigger the statement the room can make. And being that it is usually a more casual space, that works out perfectly!
