Designing Kitchens and Bathrooms - Kitchen counter top question

I am installing a counter top along a wall with two windows.

One window is wide 8' wide and then a section of exterior wall (10" wide with a vent stack inside for the sink and dishwasher), then to it's right another window 3' wide.

I would like the counter top to extend outside pass the exterior wall by about 10" so the 8' window is a pass through window (slider window). The smaller window to the right will be just a picture window. I am trying to determine do I size the smaller window bottom to be higher than the counter
top height so it's just a regular window?

or do I size it such that the large window is a pass through and the smaller window will have the counter top as the "sill" but not pass through?

Can they cut a granite that starts with a notch, then 12" over protudes 10" for eight feet, then a notch for 10" then protrudes for only 4" for another 36", then another notch for 8"? This is something typically done or would be an expensive impossible custom cut?

Thanks,

MC

Notching granite isn't a problem. Just remember granite doesn't do well coming to a sharpe point. It tends to weeken especially during fabricating. As far as the overhang...granite comes in many different strenghts. If you have a 12" overhang off the counter top...most of the time it's suggested that you put braces under it. "L" braces can be hidden quite easily. Hope this helps. Tim
