Floor Plan-- I love that there is a door from the master suite to the back porch. I would have a walk through to the laundry from the master and a door to bedroom 4 from the outside to make it into an office/parent suite.
I'd lose the guest room & dining room. Do like the idea of going from garage to laundry room & then to master suite. However, I'd have the door open into the bathroom not the closet. First Floor Plan of Craftsman European House Plan 82163
Stand up freezer in the pantry, access to laundry room thru the master closet. Would remove the game room, one bedroom, and change up hearth room and make a bigger master and dinning, no wall between kitchen and living room.
Hard to find floorplans with no formal dining room. Id kill the screen porch behindbthe master, shift the master back and expand the front porch. Also, open up the mudroom/office/utility to a big mudroom with islands.
