Thanks for your input. I thought about doing that, but want the house to be one area. The design for the 14x14 house would have a wall in the middle if I built two, or I would have to rework the design. That shouldn't be too hard, just extend it.
I have been playing with floorplans trying to figure out how tight I can pack it all in while still being functional and not have an unhappy wife for the next few years. I don't think I have to have twice the space, but just one 14x14 building will not work. I think I will look at just extending it, 14x20 or so.
