Who is the design for? family? no kids, it appears.

Arre those basement stairs passing through a wall, at the garage?

Nice work getting this far — it's a thoughtful plan, and I agree with the others about the laundry. Coming in from the garage with an armful of groceries, you'd really want a straight shot to the kitchen and a mudroom that actually catches the daily clutter, rather than a long walk through the house.

One thing I'd look at from a resale standpoint: at close to 4,000 square feet, most buyers are going to expect a fourth bedroom or a true flex room they can use as one, especially with Bed 3 being on the smaller side. You've got a lot of formal and informal eating space — dining room, breakfast area, kitchen island, plus outdoor dining — so I'd see if one of those eating areas could be simplified to free up space for that extra bedroom or a bigger, more usable family room.

Also, walk the plan as if you lived there for a week: where do guests' bags go, where does the dog get cleaned up, where do you put a vacuum? If those everyday spots feel awkward on paper, they'll feel ten times worse once you're moved in. Good luck with it — you're asking the right questions before you build, which is exactly when changes are cheap.
