Your Perimeter cabinets need to be planned with 25", for built-in refrigerators we use 26" to terminate the countertops running into them. Minimally, we use 42" between countertops. So pending on island size the math falls into place: 25,42,36,42,25 or approx 14'3 to 14'6" minimum.

I have a craftsman bungalow also, in North St. Paul. We are looking at combining the back porch with the tiny kitchen. This was exactly the idea I was looking for.
