Not to worry, mama. I want to uncover and address these issues now, so they are not a problem later. Here's what I know about the aisles:

42" b/w sink and island

44" b/w range counter and island counter (range might jut out a bit more)

On the table end, it's 5'-8 1/2" from the island to the back wall of the window seat and the bay is 3' deep. The plan is for a table and 2 chairs opposite the window seat.

According to architect, fridge door swing should not be an issue.

Sounds much better. The 42" and 44" aisles (I hope that's counter-to-counter) would be sufficient for me. If that is a prep sink on the corner of the island, I'd move it to the other corner, so that you can scoop prepped items, step across the aisle, and drop them on the range. Then you could put a shared trash pull-out on the corner nearer the range (unless you are using an under sink pull-out).

Is fridge single door or French door? (The drawing shows a single, but just checking.)

BTW, I like the book shelves beside the fridge--will they pull out to expose the broom closet behind?

Will the front room still be a living room? That curved wall and windows looks like a great feature.

Mama, I've been going back an forth on the prep sink ... not really wanting to disrupt that stretch of work space. Do you think it's a must, in this plan? As for the fridge, it will be a SZ single door, fridge over freezer. I like the bookshelves, too, and am hoping to make it a pull out to expose a hidden broom closet. (Oh, and the aisle dimensions are counter to counter.)

Benjesbride, the front room will become the DR, but could always revert back to a LR for future occupants. Because of all of the windows, I'm exposed to all of my neighbors who walk or drive by -- makes it impossible to hang out in my jammies on a lazy day! I also want to keep a formal DR, so this space suits my needs well. I'm eliminating a separate LR and making it part of the K. I have a rather large FR a few steps down for overflow.

Do you have a drawing with dimensions?

Instead of walling off a front room, have you considered just investing in nice drapery (for privacy) and opening up the whole space? I imaging that southeastern exposure could flood the space with nice filtered light with the right window treatment.

My neighborhood has a real call for formal dining spaces (and I like them, too), so a separate space was always part of the plan.

I don't think you need a prep sink, it just looked as if there might be one on the island (dotted outline), but upon enlarging the plan I see the word micro, I think.

I don't know if I have your proposed table and chairs drawn to scale, but it looks as if there might be some conflict between the fridge door and the corner of the table, unless you plan to keep the table pulled over to the right side. Moving the table and chairs to pull out the crispers for cleaning once in a while shouldn't be a big deal. Your architect's drawing might not be exactly to scale either, since the work aisle looks very narrow, but is 42".
