If the window width is large and there will be glass in the door, I'd skip any cabinet. You will benefit more from light from the two openings....a cabinet between interrupts that ..I'd want maximum light and view...these are your only openings it seems. ...not worth it for such a small cabinet. I would assume you have enough cabinetry elsewhere in your plan.

I think yes, a 12 inch cabinet will look stupid. Skip it.

Was the wall built incorrectly or just not what you were picturing? Is the wall length different now than in the cabinet layout?

Why not move the door a few inches over to the left? Very easy to do right now.

I do not think your designer will find 15 inches there for a cabinet unless you don't frame the door? Just looking at the photo, I am seeing a door that is not 3 feet wide? Do you have a door that is 3 feet opening!? to get your appliances in and out of? You surely do not want a 2 ft 4 inches exit door? By the time that is framed and a door stop installed, that exit door appear very narrow. ? Make the exit door 3 feet wide of OPEN space and make the door open to the wall, not the cabinet/counter, so it is flush and narrow that window by 1/2 the width of that widest center window. That way your 3 window bay is 3 equal windows of width? Maybe the picture is deceiving online, but you don't want a narrow exit door, and a 15 ? inch cabinet is little more interior space, than a slide out spice rack on either side of your sink? But as I say, measurements may not be accurate to the visual? Good luck with it all! Very pretty idea picture!

I can see that you want symmetry with the cabinets on either side of the window. 15" is narrow but maybe if the cabinets are glass like the ones in the picture below, then you can pull it off (these cabinets are 21"). The stacked cabinets are a bit much on the window wall. Some sort of wood valance like the curved one above the window in your inspiration picture may look good there. You could still do stacked cabinets on the other wall.

We actually use a 12” cabinet. We keep cups, mugs and saucers and a couple water/coffee carafes.

Our layout looks similar to what you had drawn up. I don’t have a full view handy, but here are a couple pics

How many inches are between the door and window now? That looks tight and clearly less space than the drawing. What measurement is on the actual construction docs? Could you shrink the window? If you move the window right then wouldn’t you have trouble with cabinets going into the corner?

Right now there is not 24” there and that dood does not appear to be 30” wide even and IMO should be wider . Who designed the kitchen? An actual KD is what you want not your architect or the cabinet guy or your contractor.

What is the intended use of the space left of the door; could you have that door moved to the left ... and how much would it cost?

There's not 24" between the door and the window, not if the studs are 16" on center. The space between the stud to the left of the window and the window is around 5", that's 21" total. Deduct 5" for casing (both sides) and and 3" for a margin and you've got 13". Remember, too, that you'll lose 1/2" after the sheetrock goes up. Tell them to move the door.

Yep. They've got to deal with it. Hold their feet to the fire.

W hat is outside the door? Could you NOT put that small wall behind the door and NOT put the door that opens inward there but, instead, add a small (about 8'x8') entry or mud room behind the door for other walls for the the actual back door? If so could you use a cabinet with that adjacent room as a "room divider" between that new opening and the next room?

No one can use a 2/ 8 inch door to move a refrigerator into a house. No one can use a 2/ 8 inch door to bring a dishwasher into a home. Now, if you have another exit/entrance door, off of a garage, that will not be draining hoses across the house(think about replacing an appliance) and is in close proximity you may be just fine. I just know that removing a door that is not open flush against an interior wall, as well as removing a door stop(the small wood trip lining the doorframe that your interior door butts up against) is just not necessary in 2018. That is the big problem with older homes. Doorways were to small. Hope this works out and you get to make changes if they are necessary. Good luck! If you do have rights and you don't use them now, you might be in deeper water in the near future...

Have you checked the dimensions of the rough opening for the window? My contractor oversized our rough openings so we can best fit the windows around our cabinet design once it is complete. (We haven't finalized cabinets yet and we want the windows flanking the range to be symmetrical.)
