Palimpsest, as a matter of fact, I was indeed imagining some very small floating shelves a few inches deep, so very subtle, but just enough to draw attention to a different focus, just enough room for something like a little vase of dried flowers or tiny succulent. I'm definitely not talking utilitarian storage shelving. At the end of the day though, even as a huge fan of symmetry, I'm not terribly bothered by the window being off center in a powder room. It'd be fine if OP did nothing, just suggested the corner shelving because it'd be a very easy and inexpensive way to do SOMETHING about it.

Do you have any electrical boxes in the ceiling that might impact your furniture placement?

There are some truly amazing options out there for hidden TVs. If you were open to any of them, that might make your arrangement easier. being able to place things without having an obvious TV in the room when it isn't in use. We have a TV mounted above a fireplace and it ends up straining your neck to look up that high from a couch. Keep the TV low wherever you end up with it.

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.
