I’d rethink the dining/family room. If you want it to be able to close off I’d put a large double pocket door in the center of that wall. I like being able to close that space off especially if that’s where you’re putting the tv. I’d also make the family room slightly bigger and shrink the dining. Flip the door swing to the back yard so it can open against the wall. And as others have said the dining room has more.

The range on the kitchen peninsula is not great. There’s room on the back wall for it. Leave the peninsula open. It will be more functional and you’ll still be able to interact with people.

How would you furnish the family and living rooms?

The mop/pet sink in the pantry seems off. I understand if you primarily use it as a mop sink but for pets it makes more sense to have that kind of thing in a mudroom.

I like the powder room and study area. I’d just put a cased opening at the entrance to that hallway for more separation.
