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.
Construction Set - Construction house plans are complete and include everything you need to build your home. Exterior views, complete floor plans, roof and foundation plans and details that explain how to build your home are included in a construction set. You want to consider a construction set if you are interested in buying a basic home plan package from which you'll secure financing and settle all the other details necessary to have your home built.
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.
Reproducible Set - You can buy a reproducible set if you think you may need minor changes made to your home plans. You can make copies from this type of home plan, but you are not allowed to build more than one home from these type of plans without a separate license.
