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.
But the difference between classical and contemporary architecture is that few of the traditional building and ornamentation methods are still being used, since modern architecture has integrated modern technology by embracing new methods of building, new materials, and an accent on functionality rather than embellishment. For example, one common feature in contemporary architecture is the mixture of stone, wood, and brick wall materials on the same surface.
Modern home plans are created en masse to suit the needs of people who don't want to customise the design of their new home. However, if you have chosen to customise and personalise your floor plan, you can do that too as long as you are prepared to tell the architect what you want. Professional architectural services cannot be replaced when it comes to building a home, so the matter is just to choose the one that suits you.
A few questions you will need to answer will include: how many bedrooms, whether or not to have a family room, if a separate study room is valuable, and if internal garage access will be important. Plans come in both 2D and 3D versions for you to review before building begins. You will want to go over these with a fine toothed comb, as changes are much easier to make on the blue prints then once actually constructed on the ground.
