I covered up our half-wall/railing that goes around our staircase leading down to the basement. We rebuilt this when we tore out the full floor-to-ceiling walls around the staircase when the new stairs went in earlier. It won't be finished of course until we mud and tape it (which we are planning to hire someone to do once the whole basement has drywall)... but it is nice to have it covered and more finished looking (meaning there aren't just 2x4's framed together and open to stairs where a small child could fall through).
A couple pictures to prove I did it!
