You gave me a great idea to install a cabinet all the way down to the granite on the right. As I am staring at my kitchen back wall, the longer length of backsplash tile on the right didn't help with symmetry. May ditch the open shelving and return back to your suggestion of even uppers flanking the windows. Now I can return to sleeping at night. Thanks Sophie for your great suggestion.

The rending has sconces, but we decided during the build to exclude them as there was plenty of light in the room already. The initial plan was for the first shelf to be 20” above the countertop, and I was thinking make the second shelf 16” above that. Which would put them 56” and 72” above the floor, respectively. Since I’m 6’ tall, I would be able to reach both shelves without a ladder. That said, it seems the consensus is to do shelves, but keep them less then 48” wide. My contractor made a suggestion about varying the length of the two shelves, or even introducing a 3rd shelf in line with the top window trim. Thoughts?

So little info. Where are you putting the shelves ? Post a pic of that space here ina comment . DO NOT start another post.. Try to match fake and real wood will always be a bit of an issue but we need at least context.
