I would agree with the others in terms of doing a LOT of reading BEFORE you start doing your building. Right off the bat, i would think that having a room measurement of 14' one way would not work well when another measurement is 21'. You would be better off going to either 20', 22', etc... One dimension should not be a multiple or divisible by any of the others. You might also want to think about building a taper into the walls so that they are NOT square or level. Sean
