Personally I think those floor plans are bizarre at best. They have taken over-sized balconies, thrown a fireplace outside and made available a sliding curtain that is open to the elements and are trying to pass it off as living space.
For one it's going to be way to cold 8 months out of 12 and if you want to fully utilize it, you gas bills are going to go through the roof as you heating the great outdoors. Very strange.
