Ceiling planks + a big, mystery hole in the wall

Ken took a vaca day and worked with Shawn to finish the prep work and began cutting and installing the ceiling planks today. In addition, the long-standing plan for the foyer/living room divider wall started to emerge today. Ken cut a large "window" hole in it. "WHY DID YOU DO THAT?!" you might be asking.... You'll just have to stay tuned and find out!
