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.
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.
Stylish house designs are readily available to just about anyone, and modern home plans offer something for just about everyone. You need to look through the available plans, compare them to your budget, and ensure that you are working with a reputable builder who will build the house that you want. As long as you keep these things in mind, you will find the ideal architectural design company and house plan for your new construction no matter what you want or how much you have to spend.
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.
