Starting a long weekend

Today is Thursday and I have taken today and tomorrow off for some long weekend house projecting. This is what Andy sketched as a possible end result (the mud room fell off the page):

It's a good follow up to his exploratory digging mission because a lot of what might change the face of the house is my idea for a little nook/alcove type area where the deck off the master bedroom currently is - Andy sees some structural gains by making that area indoors but I will let him explain it. I just see that we could use the newer sliders downstairs where they would actually be walking through regularly and have a great, sunny little book reading/lounging area of the bedroom! 

Alright, off to a productive start...
