This is pretty much the latest picture of the house. The room in the bottom of the picture is the shop, next is the downstairs master, next is the great room, and the room on the far side of the house is the grandkid's room. The rooms on the left side of the picture (starting from the bottom) are the downstairs master closet, the bathroom and then the media room.
This is the great room. There are two french doors leading out to the back yard and four windows across.
This area will be closet, bathroom and a media room of sorts.
Here's a good overall view of the progress. This basement is approximately 2200 square feet.
