I dislike 3D pics and I also dislike cabinret company plans when you are asking for help here just post a to scale floor plan showing windows doorways and where the doorways lead all measurements clearly marked and the plumbing in your case .Use graph paper to make the scaled drawing a little easier to do . Why a wall oven below the counter if you need both then get a range so much cheaper and the same functionality. I love kitchens open to DRS but not LRS so think about what you want your guests to see after dinner when the mess is visible to all from the LR.

In order to get the best advice, draw your floorplan on graph paper as Patricia suggests and include all of the adjacent rooms so people can see how the kitchen fits in to the first floor. Are you interested in opening the wall to the living room to get more space in the kitchen, or because you really want these two rooms open to each other?

What are your aisle measurements and corner of island to livingroom wall measurements? it looks like some of the dining room wall is remaining. it looks like it may be pretty cramped? my first thought is if you want to sit facing eachother and hang out a table is your best bet… i love my cozy eat in kitchen which i think is similar sized as yours. keeping either wall would allow cooktop to stay on a wall not in front of a window or on island which would be my preference…

What Patricia said. We need a 2D floor plan with all YOUR measurements.
