You want to center around the most prominent and proximate feature, which, in this case is the window. Center the table and the light around the window. What happens on either side of the window won't matter as it is already different...in width, in door placement. Strict symmetry is only for a very formal space, which this is not; or often an aid for novices who don't yet trust their eye to create balance through massing and scale. Go to houzz.com and look at some kitchens with tables...if you look closely, you'll see a lot that is far from perfect symmetry or balance, but it all works together. For example, this kitchen...the table is not centered on the island, the island lights are not centered relative to the table, but they are over the island... and the dining light is centered over the dining table....each is appropriate to its own space.

We completely redid an existing house and had to work w existing front upper window exterior that was in a weird spot. the lower ones couldnt be shifted more centered in room than what we did. you can see the ceiling drop in the pic and I am planning to move it a few inches to the left but not centered bt windows- to allow the table (96" normal length) and I planned to put a buffet (72" long under windows and slightly longer on right side to visualize space better. Opinion on that? Length of space from the left to right (to built in) is 15 1/2ft. but as you can see, if table enlarges, it will just overflow which is fine into open space. what do you think of the chandelier choices- would like to go w 9 light, but think 5 light is better sized for space...opinion on that? The picture is taken from the direction where there is a large island in kitchen area.

Thank you for your comments. I thought I'd share a change of layout plans that I'm pondering considering I didn't like either option with sink in the bay window/dishwasher layout. Spoke to the contractor and we think it's easier to leave the sink where it is, widen the window above it to be the pass thru awning window, widen the current U shape, leave the bay window as is and the 'eat in' kitchen table area. So I'll be down a dining room but that's ok, it's only a few times per year MAYBE that I entertain and need more space. I can put up a temporary dining table elsewhere (or switch over the den to dining room in the future) or make that circular table an extendable to an oval one. I may add a built in bench to the bay window now or down the road. In this layout, it's a little awkward as to what to put in the niche where the pantry is in my drawing below. It's not full height in there and it's currently where I have a sideboard but with my dining room no longer being there after the reno, it should be something else. Pantry cupboards, maybe a little desk with open shelves above? maybe a beverage/coffee station with mini fridge. I know it's a little awkward having the pantry outside the kitchen. That's the only thing that bugs me about this layout. Other option is to put the pantry to the right of the fridge. In my current kitchen this is where there is a desk and open upper shelves that definitely needs to go. It's where all the 'junk' goes like recipe books, telephone, pet food, meds, etc. so I'm drawn to putting lowers and uppers there to hide all the stuff. But it also makes sense to make this the pantry area so it's more accessible than having to walk around the penisula when prepping. So that's the dilemma/question...where to put the pantry. And what to use that niche for. Note, that niche does have a direct sightline to front door so people will see it when they walk in the front door. The area by fridge is hidden from view facing back of house Thanks in advance.

I guess the couch IS the recliner you mentioned? I don’t see what the window has to do with placement of the recliner. The recliner isn’t that tall so as to block the window. Just pull it toward the right (as I am looking at your picture, pull it right at least a foot) and maybe forward a bit towards the rug too. As is, the recliner looks as though it’s trying to squeeze itself into the corner.
