The basic idea behind the ranch style is that the major room areas in the house flow one into the other, rather than being small divided-up spaces as in other architectural styles. The access from the attached garage flows into the kitchen, to the dining area, to the living area, and to the bedrooms. The feeling of a ranch style house is one of openness and sweeping - sweeping vistas of the out-of-doors through picture windows and sliding glass panels, which open onto patios or porches where much summer living takes place.
Eaves are usually large and overhanging. Small ranch house plans tend to be simple rectangles; but there are larger designs which can be have L or U shapes surrounding a courtyard in the center visible from the living areas. Frequently there are sliding glass doors which open onto patios, or large picture windows in the living and dining areas. The design often includes an attached garage as well as patio area. Also, the exteriors are usually of brick, wood, or stucco with simple or rustic interior décor and exterior trim.
Nowadays, different types of modern furnishing plans are popular. Depending upon personal preferences people have different options to choose from furniture made of leather, fabric, wood, steel, and glass.
Aesthetics is in the eye of the beholder, and it depends upon the prevailing tastes of the time. A building's functionality, or fitness, is a matter of how well it accommodates the purposes for which it was built. Its structural integrity means soundness - will the building last over time? Historically speaking aesthetics has usually trumped fitness as the overriding factor in architectural design. Classical architecture was preoccupied with articulating features on walls and facades. Modern architecture is equally concerned with aesthetic formalities, such as form following function.
