Many firms offer pre designed plans that can be changed to accommodate individual tastes and preferences. There is a huge range of plans available online and from architectural companies - your task is sorting through all the various elements until you can narrow down a list of crucial components to be incorporated into your plan.
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.
It is wise to speak to your architect about potential roadblocks in the project and about any other extras that are likely to be added to your bottom line figure. You may also want to discuss anything that your architect may think is a better design choice.
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.
