This is beautiful. From the look of the kitchen island and the bar stools, the kitchen is likely to be nicely done as well. I like the loft for a guest room. I would also consider sliding barn doors as a separation for the bedroom.
This would be a dreamy area and perfect for cats and humans alike (and dogs who have allergies to random outdoor things). I would set up my garden and studio in there, and put together a few little sitting areas too!
