Fire hazard and very visible. Start over. 100%. You need to ditch the gawdawful corner sink as a start. Find an actual kitchen designer.

I don’t understand why you are considering not lining them up… I also have to agree about corner sinks- there is almost always a better place.

I actually love corner sinks, and being able to look out the window while doing dishes is huge to me, but I know many people don't feel this way, so I've thought about alternatives. I haven't been able to come up with one, short of redoing the windows.

Just because you cant think of an alternative doesn't mean that someone else can’t either.

Post your floor plan.

Hallett & Co, I'm not lining them up because the corner sink extends 42" from the wall and the window only 41", and I don't have the full 78" for the cabinet run on the bottom (hence shrinking one of the lower cabinets to 21") but do on the top.

Using a 36” range hood will provide wiggle room of the range hood not lining up with the range. It looks like you are planning a OTR microwave? You will need a trim kit to make up the difference.

Sorry still don’t get it- adjust one of the drawer units to be smaller. Way less of a visual problem then mis aligning the hood and range. That screams mismeasure.

OK. I'm posting my updated drawing of the floor plan along with an old computerized one a designer did for me that has a lot of things off. Also, here's her picture of the main part of the kitchen. In the unpictured side of the kitchen, the current plan is to put a corner window bench and small table plus recessed shelving/cabinetry in the wall to the dining room (that gets complicated, but it's probably just important to know where that wall is - namely the surface facing the dining room is 12" to the right of the window; how thick that wall is depends on where it starts relative to the window in the kitchen, but it currently starts 7" to the right of it).

*edited to add a rendering of the "unpictured" side of the kitchen where the recessed shelving is represented as pictures plus shelves because I'm not good with tedious things.

I'll add that I don't like open floor plans and we close the doors so we have separate spaces for my son to do zoom classes and such almost every day.

The attempt to do the weird attached island thing in a kitchen that doesn’t have room for any of that is really messing up the actual function as a food production room of the kitchen as a whole. Ditch that.

Put the sink under the other window. Put the range on the end wall where the fridge is. Put the fridge where the weird peninsula thing was, with a small pantry next to it. Now you have an efficient and functional kitchen, with a nice prep zone in the corner in front of the window.

I can’t believe I am saying it, but I agree with Verbo on this one. And I would never not line up the hood and range

So that would require redoing that window, which was really not in the cards. But maybe I have to, if this is really that dysfunctional.

It doesn't actually feel dysfunctional to me, though, and I was kind of looking forward to the large island-like prep area where I could also see into what my kids were doing in the living room, cook while my kids do homework near me, and cook with my kids. Is it really that awkward? I've been thinking about shrinking it a foot, so there's more space in front of the fridge and for the path to the living room (which is currently almost unused, but that's likely because the fridge is right there making it feel fairly closed off).

I am hearing that things really need to be completely aligned, so I guess that means shrinking everything down to 21" single door wall cabinets. Blah. But then I need an extra 3" in the run to keep symmetry around the windows. Can I put a 1.5" filler on either side of the range and overhead cabinet and microwave/hood? That would look ridiculous, right?

Your space isn’t that large, but with your constraints, Have you looked into a local custom cabinet company, who can site build cabinets to fit? RTA may not make sense for you

Rereading your original post, I see you want to install the uppers lower than standard as well, so you can get the look you want at top. You seem to be trying to cram a lot of things in at the expense of functionality. The fridge will be nearly impossible to get to, that corner is so cramped by the massive peninsula.

What looks ridiculous is the island peninsula thing. Not every kitchen gets an island. And thats more than OK.

Uppers and lowers don’t need to be the same width, but hoods have to be directly over stoves (for code and visual reasons). Adjust the width of the left drawer bank and everything you want fits right?
