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.
We used Behr Black Suede flat on all of our doors in our home. With the original glass knobs these doors are on fleek! The walls are Benjamin Moors Revere Pewter, which was used throughout the entire house!
