I am buying a house with a landing at the top of the stairs. There is a short half wall all the way around (about 3 feet tall). I would like to add a banister along the top of this half wall to keep kids from trying to climb but I don't want it to be too tall. I'm thinking the banister should be around two feet tall (for a total of 5 feet). I have absolutely no idea where I could buy something like this or how much it would cost. I can do the work myself but need to find somewhere to buy the materials. If I have to buy longer ones, I could but I would prefer to keep it short. Also, the half wall ends on both sides where the stairs come up onto the landing. Is it OK to attach a newel post on top of a half wall? I would need to do this on each side. Thanks for your help.
