It’s a great start. Is there a reason your interior walls are thicker than exterior?
Plumbing walls. When you’re talking about new construction, it’s cheaper when you have plumbing on common walls. So in places like your half bath, I would flip it to the other side so it can share stacks with that hall bath.
Closets. It seems really weird to have that closet off the wall facing north in the kitchen. If anything, I’d do built ins or else leave that wall blank. I would not have the two closets off the master. That one master closet is way too large. It looks to be larger than the bathroom itself or close in size to the size of your office. I would want my washer and dryer in the mud room and not use stacking ones. Usually stacking has a lower capacity. That pantry is a ways away from the kitchen for me.
Dining and living room. I would flip those spaces and shrink the size of the dining room. It seems really large and pretty old school having it have that much of a defined space. Move the entrance to the office off the hallway for noise and privacy.
Entrance. Personally I don’t care for the entrance facing the side. I don’t think the first thing people see should be the garage. “All glory to the car hole” just isn’t what I would like. Maybe, I’m alone in that though.
