Small house plans are normally defined as houses with less than 1800 square feet, excluding a basement. These house are also space efficient and less expensive to build on a small plot of land.
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.
The field of drawing custom house plans is a crowded and competitive one. There are many architectural and design firms out there vying for a "piece of the pie." However, if you look closely at examples of their finished product, you will find huge differences among them. The better ones offer quality designs and highly detailed plans.
Study Set - This type of home plan includes complete exterior views of your home to be plus floor plans of the upper and lower floors (for two story homes). A study set is useful in helping you determine if you can afford the home you are considering building. Usually excluded from a study set are items such as the roof, foundation and details of the home.
