Simple floor plans for a house show two bedrooms, one bath, a kitchen and a den on one level. The den is sometimes referred to as the family or living room. Cottages, ranch houses and cabins use simple plans.
Homes built from a simple floor plan are economical and environmentally friendly. Fewer building materials are used in construction for reduced costs and impact to the environment. Typically, the bedrooms and bathroom are placed on one side of the entry while the kitchen and den are placed on the other side.
When expanding with additional bedrooms, bathrooms, a dining room or great room, the floor plan follows the same principle. The bedrooms and bathrooms are located on one side of the house or on a second level separate from the kitchen and living areas.
