Also check with your local building officials as to the total square feet of building coverage allowable on your lot. Pre-existing Conditions Plan any new bathrooms near an existing bath to cut down on plumbing expenses. You will want to make rooms accessible and not out of the way. Bedrooms should be at the quieter part of the home.
Bathrooms tend to be at the back or sides of the home.
Kitchens generally at the front. Today's home designs are more open and airy. Kitchens that open out into the family room give those working in the kitchen the opportunity to mingle with dinner guests, or the rest of the family as they prepare meals.

The bedroom should be spacious enough for a king size bed, with two options for placement.
