Hi lland3,
To answer your question about the length of this wall, it is 15' , or 180," from the arched main entry opening on the far left of the photo to the smaller arched pantry opening on the right side of the photo (you can see a bookshelf which is to the right of the pantry opening in this photo). Each built-in fridge is nominally 36", so after we add 1.5" to each side to enclose the appliance in cabinetry, we will need a minimum of 39" in width for each of the two fridges. After that, the cook top is a 36" wide, and the base pull-out spice and sauce cabinets (one on each side of the cooktop cab) are each 6" wide. In this kitchen, this range run became important as the main focal point from the family room, so the design team wanted it to appear symmetrical despite the non-symmetrical functionalities of each area.

So from your details, and if I added correctly, the hood above is 48"w? How much clearance above range is it placed? Thx!
