Streets and topography may be the main determinates of a house's orientation, but it's also a good idea to consider sun exposures when possible. A homeowner might reorganize a floor plan to take advantage of morning and afternoon light. Martin says that covered porches that face a southern exposure can help block out heat and sunlight.
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.
One item to look for when evaluating a house plans' quality level is the number of structural sections which are shown on the plan. Highly detailed sets of plans will always cut lots of sectional views through the house to show every different roof framing situation. This might mean that 10 or 12 (or even more) sections need to be drawn for a large house plan. And even a small house plan should include 3 or 4 sections minimum. However, many home plans available today (especially plans purchased through inexpensive plan directories) cut corners in this department and only show one or two house section views. This means that the builder will have to guess at the rest of the house framing.
Complimenting your lifestyle : Before delving into the thousands of plans available today, evaluate your current living situation. Look around and ask what works and what doesn't. Consider which features matter most to you and which floor plan best accommodates your family's lifestyle. "Does the floor plan live the way you live?" Martin asks. Are you an empty nester who's ready to downsize? A single-level ranch home might be your answer. Is this a house where you expect to raise a family? Check out plans that feature great communal spaces as well as a private master suite. Would you live outside 12 months a year if you could? Pick an airy floor plan with plenty of porches and more windows than wall space.
