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.
In addition, good stock plans come with a detailed inventory, which you can use while you're developing out your dream house. This is important for two reasons: you can look at the materials used to build your house and determine whether your budget will stretch to accommodate them, and you can get a very good idea of where to upgrade and downgrade materials.
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.
