Residential interiors are obviously much freer and much more personal for both the interior designer and the occupants than other types of interiors. In fact, homes that have been designed unconsciously by creative occupants without any standard decorative rules are often the most beautiful ones. Certain planning and functional considerations are constant in any residence, and, although these too may be ignored by the occupant who wishes to be strongly individualistic, they can provide at least basic guidelines.

The planning of modern houses or apartments must take into consideration the location of certain needs in relation to others. The dining space should be near the food-preparation area, and the food-preparation area should be accessible to the entrance used to bring in food supplies and remove waste.
