The typical modern american house consists of at least six main types of areas:

1. Living and Recreation Space. In any one dwelling, this can include a living room, family room, den, library, music room, sun-room, or other rooms and niches planned for entertainment, relaxation, hobbies, or study.
2. Food Preparation Space. The kitchen ranks number one here, followed by additional food storage areas such as nearby walk-in pantries and “satellite” serving platforms, bars, and grills conveniently located in family rooms and other living and recreational spaces.
3. Dining Space. Depending on the floor plan, this can be a separate formal dining room adjacent to the kitchen, or an open dining area having the kitchen on one side and the living room or family room on another. Or, when economy is desired, a portion of the actual kitchen itself can be reserved for a dining table or booth.
4. Bathing and Washing Space. This means bathrooms, both full and half, plus toilets, hand sinks, showers, saunas, and indoor hot tubs.
5. Sleeping and Dressing Space. Bedrooms, dressing nooks, and related storage areas.
6. Service and Storage Space. Everything else in a house fits in here: basement, attic, stairs, hallways, laundry rooms, and garages.
