Some lower cost cabinet lines don't even offer that, but it's a better option than a filler IF you have and installer that can truly scribe it to fit. Too many jackleg installers can't these days.

Just make sure that if it's done on the base cabinets that it's mirrored above. If the wall is out of whack, it's out of whack top and bottom.

Thanks LWO. I will keep that all in mind. Not sure on the scribing. I will have to ask.

I am thinking if it's measured and framed well it should all fit. Is that taking too much of a simplistic view?

Autumn- looking at your elevation I understand why kd wants to do it-to ensure hood and range are centered between windows-precisely. An extra 1-1/2 is overkill if cabinet sizes can be changed.
Without seeing the space, checking square and dimensions, scope of work on wall and windows- I would not say if it needs to be done or not. The one thing I notice is that there is no adjustment possible with the wall cabinets. Also notice that molding extends past wall on left.

Can it be done with just exact measurements- sure with a good installer, square corners and a level floor help immensely. Out of level and out of square gets tricky. It is riskier in all cases.

One advantage is that at least one brand your considering will alter cabinet sizes to 1/8 at no charge not sure about the other two.

Discuus fit with all 3 and then judge what they say and why. Have they been out to measure yet?

They haven't been out to measure. I was assuming I needed to choose one first and then they all said they would come out and measure and direct the framer regarding window rough opening placement.

Is it showplace that does 1/8th no charge? I am still waiting on that quote.
I believe Shiloh does adjustments without added cost unless it's depth. I am starting to get them confused....

Shiloh and Medallion were both confident in orchestrating windows with the contractor.

Is this window layout particularly difficult? In other words should I be worried?

Yes Showplace does size reductions, (h,w, or d) no charge. I don't know specs on the others
Windows not difficult. If new or moving then shouldn't need the extended stiles, just good layout and coordination with installer. Assuming they are on the back of the house.

Thank you jakuvall. They are on the side of our new build and face the woods so we are okay there.

I am anxious for the quote! :)
