I wouldn't want to eliminate the front closet altogether, but perhaps scootch it up away from the front door.

How low is the window in the front corner of the kitchen? Hoping it has room for a counter below. Are you able to open up the wall at the top of the kitchen?

I'm not a pro, but I'm thinking along these lines:

I don't love the fridge placement in your plan, because it isolates that window and cuts off the light from that window from the rest of the room. My idea is to recess the ref in the spot where the front closet is now. Between ref and lower wall is a pullout so your ref doors don't hit the nearby cabinets. Cooktop on lower wall. (Hopefully that will work between the window and corner; more measurements would help.) Peninsula between kitchen and back hall; no room for stools there, but it would open up the kitchen a bit more to your dining space.

re: the stacked washer and dryer, I think in one of the closets in the sunroom is the best spot. That wall already has plumbing because of the bathroom, and the spot is between the two bedrooms where most laundry is generated.

I love the idea of having the fridge on that wall to keep the light through the window. I will talk to my contractor about that! You don’t think it is possible to do seating at that peninsula? Is it because it butts up against the door? I originally was putting the laundry stack by the 1/2 bath because plumbing is already there w/ gas due to water heater. Thoughts?

I think seating at the peninsula would block that back hall. Maybe it would work if you got stools that slid completely under the counter. But then you'd need that top counter (by the back door hall) to be deeper, and that would shorten your leftmost counter where the sink is. I wouldn't want to cramp the space by the sink.

re: the washer and dryer near the half bath: that would mean taking space from either the half bath and BR2 closet, or from your dining space, yes? Either way, I don't love have the laundry intrude on your dining space. You have a nice corner there for benches or chairs and a table and it's right near the kitchen, so I'd want to leave that dining area as is.

It might help you to draw this out on graph paper, to scale, with your furniture (or wished-for furniture) drawn in to scale.

I would do something like this. Is there a door at the end of the hallway next to the kitchen ? Either way, if there is a hallway, I would not remove the way. Having the wall also provides additional storage. You can also create arch or a simple square opening in the hallway, if that is necessary.

Your trusses or joists, which way do they go? Should be across the space and the post you show should not be necessary. A contractor is not a structural engineer. Remove the wall and closet. You then can configure a functional kitchen with an island. All drawer base cabs. You won't need uncomfortable seating with a dining table with normal height chairs right there. I'd cut the wall bryween the kitchen and the powder room back some.
