You have a good nice project planned here, with your kitchen now a part of large living space. Here, though, are some cautions and suggestions. Your extra-large peninisula counter and full window wall over the sink seem to be features that you like and want - but they also cause some problems with this plan. If two people are ever in the kitchen, one will be trapped there. And even for one, the peninsula forces an irritating hike around it to the table for serving and clean-up. Table and array of counter stools are uncomfortably close together, creating congestion especially when occupied. And while your back wall may well contain a fridge, wall ovens, pantry and cook-top, it would just barely do so - and leave no other space at all for counter. This, together with your nice bank of windows on the outside wall leave no space at all for upper cabinet dish storage. I agree with Laurie that an island here would be much preferable. I would put the sink and dishwasher on an island, with fewer stools, and some mid-height dish storage - letting gatherings of more than two or three enjoy the table in a conversational arrangement instead of facing away from the room in a row. I would also minimize the window array a bit, and extend the kitchen toward the dining table window a foot or so - and put the wall ovens at this end of the "L" - with no side wall at the left. This would distribute your countertop space more happily among your work stations, allow for some upper cabinet storage, and make the kitchen feel more part of the nice big room, instead of separated from it by the peninsula. Perhaps a careful in-person visit with a kitchen designer would be wise before you build this fun new addition. Good luck! Mark

~$400 including expedited shipping. My GC just had his regular countertop guy do them, which wasn't great.... he had trouble making clean cuts. If I were going to do it again I would have pressed for someone with expertise to cut them. You can see in the image that the facing is not made of the stone peak, because too much was broken during the cutting to make the mitered edge. I'm a little bummed, but mostly pleased with the surface (which is the important part) thus far.

Wow, that was awesome Mark, thanks for that and everyone else. I thought about the desk facing the other way actually, to avoid feeling enclosed I do have really great views there so I thought about a small couch and maybe a bookshelf on the back, but having the dining table in front is probably not the best either.... complicated :( Here are a couple more pics, today was a beautiful day so I managed to get more of the views

How about butcher block instead? IKEA and the big box stores sell it for countertops, the price is decent, and you won't have as many issues with buckling, water damage, or what to do with the edge as you would with the ply. If the edges of the ply get wet, or if any seam around a sink gets wet, the plywood will "blow" and you will have to replace it all, anyway.
