seems that due to the centered farmhouse sink under the window, along with centered faucet under the window, the differences up at window sides don't really get noticed. As well, you have centered door opening right under sink .To me, the eye moves from the window straight down the line you created rather than moving left and right. You could nudge the horizontal cabinets to the right an inch and still regard the center of those two as basically lined up with corner of the counter on that side. That's the only thing I would bother to tweak.

My cabinets were installed with an uneven gap, and it bothered me but I didn't say anything. Thankfully, it bothered my GC, too, so he moved one cabinet and added a filler.

Thank you, everyone. I love the chiming in that helps me crowd source. :-) Suzanne_si - thank you so much for the picture. I am studying it and visualizing my space!

P.S. The upper to the right of my sink is 18" like the one you ordered.

I'd move the upper left over towards the window 2". don't think keeping them lined with the peninsula is important.

Some things being unequal would not bother me, and I probably wouldn't notice, but I would notice uneven spaces around a window. I'd move the left cabinets toward the window.

Another vote for moving the left cabinets toward the window.....in case you need more encouragement. ; )

OK, sounds good to move the horizontals over 2" for consistent window spacing! Thank you! Looking at my current set up, we have only about 1" and 1.5" on either side of the window so a change to 4" is definitely going to feel more open. I don't think I need to go to 6". Lilysmom, I didn't think about the effect of window coverings! We will probably do a roman shade style vs. curtains.

Are the different cabinets on either side not both 18" above countertop? They don't look even to me. That would bother me WAY more than the small difference of blank wall on either side of the window. Can you not just change the window?

Anglophilia, the cabinets will be the same distance above the countertop. Might be an optical illusion in the rendering. Window is staying in place - cabinets are not up yet and can be adjusted easily.

I, too, was struck by what appeared to be different height cabinets on either side of the window. I think that concept of an optical illusion is really interesting and you may want to explore that before you get the actual cabinets there. Have you been through the IKEA show room-do they have a model in there?

While it is possible to put cabinets right next to the window frame, I personally prefer more light around the window and so would (1) seek to maximize it and (2) make it the same size on both sides. I believe that there is actually an equation that designers use that explains the minimum distance based on the depth of the cabinet. Maybe one of them will chime in here.

Can you put the same glass that is in the cabinets to the left into the cabinet on the right side of the window. I think it will give better visual balance.
