Hi Louis, I am a contractor working in Durham everyday. I have done remodeling, and new consrruction, both for my own business and for others for over 20 years. Part of my services involves space planning. Moving a kitchen from the backof the house to the front just because you have seen others do it shouldnt be the main reason for moving a kitchen. This is a very expensive idea. You should look more at how the house flows. Is the kitchen near the eating area? Does it flow into the main living room?
The only time I have moved a kitchen, was if I were revamping an entire floor plan. The kitchen is the central part of the home and is key to flow and how a family would use the home.
I have never had any comment from a potential buyer wishing the kitchen were on the front of the house. To my experience, location of the kitchen as to front or back of the house makes no difference, but rather how flows with the rest of the house.
