Let me try again on the layouts - this was my first try.

Here is the first floor

Is swapping the dining room and kitchen an option?

what's the length of the kitchen from backside of stairway to back wall (at top of layout)?

is there access under the stairway from the kitchen side? from the hallway?

what is the rectangle between DR and kit? measurements for whatever it is?

Nightowl - I had never thought of switching the kitchen and DR. The kitchen might be too narrow to make much use of as a DR. I'll double check the measurements.

Desertsteph - the tiny space under the stairway is accessible from both the kitchen and the hallway, but both are narrow passages. Its a pretty small closet - 26"W by 30"D. The access from the kitchen side is a whopping 26" - can't really be widened because of the support for the staircase. That is why I thought of just using it as a niche for the bath vanity. The hallway access is 24". The length of the kitchen up to that closet is 285"

The rectangle between the DR and kitchen was previously a penninsula - 90" long and 24" deep with a 10" overhang on the DR side. I had thought to keep it. But it can go or be modified.

Is it possible that you could angle the corner of the powder room? I
know that's more difficult and more expensive, but it would allow you to
move the fridge against that wall, and leave more room for prep between
the sink and range. I'd also move the cooktop toward the sliders, leaving
just enough space for comfort and landing, 18".

On the other
side, I've recessed the ovens and pantry into the space now occupied by
the peninsula, and left 3' of counter for serving, or pulling up a
stool. The peninsula could be like a table, open underneath, or cabinets
for storage if you don't need the seating. You could also store a small
mobile cart underneath, and pull it out for prepping when needed.
Beside the ovens is a shallow tall cabinet for storing cans and jars.

I'm having a difficult time reconciling the scale of your two drawings, so I put the basic plan on both of your images. If the second image (R) is more to scale, then there appears to be room between the PR and fridge for the pantry cabinet. In that case, I'd still move the cooktop toward the top sliders, and recess the ovens into the current peninsula space.

Thank you - yes, the second image is more to scale for the actual kitchen. I didn't use the same scale because i couldn't get the entire floor plan on the graph paper if I did. I'll mull on the angled PR wall - I had thought to use a pocket door for the PR; if we angle, the door will have to swing out as you say. But it may be the trade off is worth it. I'll double check the width measurements there to make sure it can swing out.

Would you have the pantry cabinet - either between the fridge and the powder room or in the current penninsula space - still be 24"? I'm not very experienced with gauging the proper size of cabinets.

I'm wondering why you moved the ovens over to the pennisula rather than keeping them in the little nook by the sliding doors - Is it because it is too deep there from your point of view?

I played around with this off and on this morning. My attention is always divided, so I apologize if I missed a critical piece of info. Your space kind of reminded me of historian's, so rather than put the powder room next to the stairs, I put it at the back of the house near the back door. Since you're low on storage, I thought you could instead put a spacious closet next to the staircase and possibly gain access under the stairs for additional storage. I also thought your dining room's width is rather generous and it wouldn't hurt it to route hall traffic to kitchen through there; it might improve traffic flow and sight lines.

Personally, I'd rather have a swinging back door and windows and base cabinets rather than sliding glass doors, but this is my own thing; I've replaced sliders with full-lite swinging door and windows in two houses now.

Perhaps this will spark useful ideas...

Prep space should be at least 36", between sink and cooktop. I was too lazy to do the math before, but if the kitchen is 285" long, fridge is 48", DW is 25" (I added the side panel for the DW so counted 25"),
sink base is 33", and cooktop is 30", with an 18" cab to the left, you
should have room for 36" of prep space, and 95" split between pantry and powder
room. What's the length of the powder room?

With a pantry on that side between the wall and fridge you could still keep the 90° corner and the pocket door on the powder room. You could also have another pantry cab, maybe 18", beside the oven.

Yes, I thought recessing the ovens would leave more floor space, and more step-back space for opening them, since the kitchen is a main traffic area.

Can you open another doorway to the front hall from LR and have a narrow powder room by closing the kitchen-hall doorway? Something like this?

With the 2nd doorway from LR you may be able to use the coat closet more and may also get another shallow closet opening to the DR.

I kept your kitchen layout the same, but now you can have more cabs b/w the sink and the range for prep.

Sena - thank you - that was a plan that I had explored but my plumber vetoed it because that entire area underneath is consumed by ductwork for the furnace, which sits right underneath. Opening up the wall to the LR/DR would have required moving some electric, but not impossible. Once upon a time, there had been a doorway there.

Mother Goose- thank you so much. I overstated the length of the room - its 280 now that I double check. The powder room is going to be about 57" (because that is where the toilet drain can get past the ductwork and joists below). So - from the top of drawing, if I've done proper math, I could do:

18" base

30" cooktop

18" base

30" base (for 48" between cooktop and sink)

30" sink cab

25" DW

48" fridge

24" pantry

Powder room

Benjisbride - I can't do the powder room at the top unless I switch out the slider because the width from the slider to the wall is only 25". Or.... Could I leave the sliding door in and build a wall just inside it - so the door still slides but there is an enclosed room? Would that be wierd?

Mama_goose's angled wall idea may work with a corner toilet I think. I like her recessed oven.

Edit: I don't know why I didn't see your last 2 posts before I replied.

Anyway, if PR will be 57" after the closet I think you'll have enough b/w the sink and the range. I'm no expert, but you may have to resize some of your cabs because you may need panels/fillers b/w the cabs and the wall.

If you like the floor plan with the powder in the back but want to keep two sliders and the only obstacle is the slider on the back wall, I'd change it. Can you just swap the rear 72" slider for a 60" slider?

In a previous home, I put the powder room directly into the hallway, facing the back yard, and backed it with a closet facing the foyer. I was worried that the circulation would not work, but it actually made no difference. My hallway was wide enough for the required toilet space width (30") plus space for a narrow wall hung sink.
