This is what the basement looks like.
This is actually the main floor, but the basement is a carbon copy except that it is all one room, with no wall, and instead of three small windows, there is one big one on the right, and then the exact same sliding door on the left. I did not take a picture of the basement bacause all of the other guys boxes are on the ground...

Since the one wall is almost all window, I will have the piano facing the other wall. I don't imagine that water could back up and flood up into the basement, because the "basement is actually above ground...and the backyard falls away into a cliff in about 20 feet.
Also for consideration, the floors are exactly the same, but the walls in the basement are only 8' high. As for the lighting concern, we face south, so natural light is always pouring in.
Because of the nature all around, I would like any ideas you may have with natural decorations too. Slate, wood, rockwork, etc, although I guess that may be a little mature for most kinds
