Know what to ask designers. You need to talk to these people before you choose one to work with and asking the right questions can make all the difference in the world. You need to find out how long they've been in the business of designing home plans, what they have done in the past, and see what they can do for you. Make sure you look at a collection of other houses they have designed; this will give you a solid idea of the quality of their workmanship and creative talent.
An open floor plan leaves more room for light, a good flow of energy through the home, and easier access for many people. When researching modern home plans, a lot of people choose open floor plans in the contemporary style just for the sake of sheer convenience. When they have small children, it is easier to see across the home and make sure that their children are safe without having to constantly be in the same room. There are plenty of reasons for choosing a floor plan that is open, but this is actually a popular reason.
Also characteristic of the ranch style are open floor plans which permit rooms to serve multiple purposes. Ranch style houses frequently include separate family, living, and dining areas which can be converted as needed into entertaining or hobby areas, or into extra bedrooms when required. Although a single level ranch house plan with front porch or patio is the norm, there are also split level ranch houses and raised ranch houses which have more than one level of space.
Ranch style architecture originated in the United States in the 1920's, and it became very popular after World War II as cities expanded into suburbs and inexpensive tract homes were needed by a growing populace. Ranch style houses are most popular where land is inexpensive and the weather is mild, since these homes particularly lend themselves to outdoor living. The low, earth hugging look with clean, modern lines of the ranch style is derived from Frank Lloyd Wright's prairie style architecture.
