A few things I see. Your barstools are going to block the aisles in the kitchen all the time and not be usable.

Two things that I think make your home really hard to sell: The master door through the formal dining room space. Walking past the laundry to get to your master bath.

I would bring the master bedroom door through the left side of the kitchen (by the stairs). Pantry could be moved accordingly, or there are some really neat pantry spaces done under stairs! (I am planning a huge pantry for canning and I honestly think the under stairs pantries are awesome). You could put a regular height set of paneled french doors to access it and the ceiling would have a slope down when you opened, but you would essentially have the same amount of storage.

I also do not like the only laundry access through the master bedroom. It will make the house hard to sell. It would be fine if you had laundry upstairs. I would put the laundry on the left side of the moved master bedroom with a 2nd access through the mudroom space. The mudroom/laundry/closet wall on would be straight on the left side. Then arrange the bathroom to the right of the master.

Is this a complete remodel of a house or a new build? IMO put the laundry up stairs and forget the chute idea or put it in the mud room they are never best inside closets where you hang clothes.Everytime I look I see another issue. Do you have an actual architect?

While it's certainly handy for you to have access to the laundry from your closet, there are issues with it. 1) The third person (child?) has to go through your bedroom to do his/her laundry. 2) kids are known to throw their things in the wash or the dryer at odd hours. In fact, my DH and I are known to put things in the dryer late at night, DH will start a load when he gets up at 5. 3)Now, my family is not your family, but laundry is a family affair and I wouldn't want it in an exclusively private area.

Don't worry too much about a laundry chute. We had one growing up and while we used it for a little while, eventually it was just as easy to bring the laundry down the back stairs (which wrapped around the chute) when we left in the morning. And if you can't have it drop right in the laundry room, it defeats the purpose.

What side of the house will have the driveway/garage (ie family entrance)? And where is the front door?

how often will you or hubby sit in the bedroom to enjoy the view?

If the bedroom door were over to the right, by the exterior wall, it would actually be a bit more private and you could "steal" some light/view from the dining room windows.

But...when your son has friends over, whether to play cards, have a snack, or do homework/work on projects, they are likely to be at the dining room table, right outside your bedroom door.

i wonder if you have room to expand the back of the house a bit, and create a small hallway between the kitchen and master suite? That hallway could be the access to pantry, laundry, and your bedroom suite. The laundry then is accessed from the hall for your son, but also for you, since I doubt you spend your non-sleeping at-home in the master suite but rather in the working part of the house; the laundry is still close to your closet. You could probably configure it so the laundry also opens to the closet.

edited to add, I was typing as you were posting! Ideas travel through the air lol
