I wouldn't know anything about custom walls or floors. The existing floors are good enough for me, and when in doubt, there's always concretium.
The existing floors are too dark, and the room, even with many windows, is still dark, and the environment rate is reduced.
That's why I downloaded many floors with "light" color (white, pale yellow, pale green). I don't use anymore the red/dark blue/dark green, etc colors. The "light" colors lighten the room, but even with them, I have to turn on all the lights, in all rooms.
Besides, you are a man - and men are not obsessed with decorating...
