Please post a photo for good advice that relates to your space. In general, I would recommend that you install some sort of window covering that will give you enough privacy at night while not cutting out all the light through the glass. Motorized blinds (with a wall switch) might be a solution. Or you would do a custom glass panel that is all or partially opaque.

The best way to get advice on Houzz is to post a photo with your own thoughts. What do you like? What is the style you have in the home?
