Another service provided by the companies that design and sell house plans, is one that allows you to estimate the cost for building a particular house in your area of the country. The South is the least expensive area to build in and the West has the highest cost .The national average is somewhere in between.
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.
When you decide on a house plan, you're also choosing a way of life. Do you host dinner parties often, or do you only step inside the dining room on holidays? Today, many families forego a dedicated formal dining room. Instead, a casual eating nook connected to the kitchen accommodates week-night meals, Little League pizza parties and all their entertaining needs. If you work from home or have school-aged children, an office or study may be a necessity. Think about the rooms and how you and your family will use them.
Every set of custom house plans includes several items which need to be blown up and detailed for further clarification. If a set of plans does not provide additional close-up drawings (for things such as beam connections, deck railings, stairway construction, etc.), then it is not a complete set. It is very easy to cut corners during the planning process. But the end result will be higher costs for the home owner - and lots of frustration for the building contractor.
