Can you clarify what you mean by an all freezer? I just went through a gut to the studs of a 1980's weird kitchen so i understand your concerns. I put in freezer drawers in my kitchen separate from the refrigerator. Yes I did the same thing and put in a beverage center with ice maker and microwave to keep people out of my work triangle. I also use it as a butler's pantry to service the living & dining room. If you mean an all freezer as a deep freeze for a 1/2 side of beef, that doesn't need to be in the kitchen, but I would then include freezer drawers in the kitchen area. One last piece of advice, pay for detailed plans but don't order your cabinets until AFTER the kitchen is gutted to the studs. Yes this means more time without a kitchen, but they did some weird stuff in construction back in the late 1970's and early 1980's. We found hiccups to what we thought we'd be able to do after the demolition and by waiting we ultimately saved ourselves some big headaches and $. I went with drawers over door cabinets everywhere and I love it. I also put pull out pantry columns next to the stove and oven. I now wish I'd put in 2 more because I use those all the time because they are so convenient. Remember design the kitchen for how you live with focus on reducing steps back and forth.

This is what I mean by a pull out pantry column. (Not my kitchen)

All freezer as in the big 36" subzero column. My home is built in 87, and we don't have any weird construction issues. We know where all the uitilities are (we have the full set of original plans down to the structural calculations used for each load bearing wall).
