Having a custom drawn designed house means a professional architect applies his skills limited to the individual homeowner's needs or what they have in mind. Factors considered in such a situation are the size of the site of construction, ideas of the individual homeowner, population around the area, and the nationally and locally existing building code plans. Time is also a considerable factor for completion of a custom designed house.
There are a few aspects that you must finalize in your mind, before looking at the different online designs. You need to visualize the structure of the house with respect to whether there should be a basement, how many storeys you would like to have, the number of garages that you want, whether you wish to have any outside water pond, the size of the house, the sizes of the different bedrooms, kitchen, living area, etc., and the amenities that you want like bathroom tubs, sinks, and fireplace.
Building a house of your own choice is the dream of many people, but when they get the opportunity and financial means to do so, they struggle to get the right house plan that would transform their dream into reality. It is a long and complicated route from the first conceptualization of a home to the house designs, floor plans, elevations, cross-sections, structural designs, and finally the completed house plan that will ultimately form the basis of the construction of the home. Most people do not have a clue as to where and how to get house designs, or even to get the right designers who can do this job for them.
If you find a house plan that you love, but want to make minor changes, most companies can have their designers do that for you, at an additional fee. It is also possible to have your plans reversed, for instance, if your breakfast nook faces west but the view from the north side of your lot is more attractive, you can reverse it. Many of the sites selling house plans will allow you to see a reversed view, of houses you might want to build.
