This is a great plan. Great upstairs deck over garage. Kitchen & dining open onto deck. Course I'd arrange different as I want the kitchen to open onto livng. Dining by entry as usually your dining room is clean. Plumbing consolidated. Utility open to garage. I'd put some storage under stairs. HAve a garage door open onto deck from garage. Change the utility/bath area a bit to combine/add shower. Ugly facade though. Try Spring Green.
