Oh no, no, no bad all divisable by 2.
not good.
We could probably change the 16 to either 15 or 17. The 8 for height is a rough guess, as we have 9 foot ceilings in the basement unfinished but will lose some when we finish. If we put the room where we think we will at the moment, the 10 across is about as wide as we can go due to the steps to the basement being in the middle of the basement.
The link is to a layout of what I'm working with, but the picture is really small. You should be able to zoom and make it bigger, but blurrier too....hopefully it helps a little.
