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.
Remember that plans are not necessarily "as is." Builders can use a reverse set of plans (sometimes called a mirror image) to better site a house. It's also possible to hire an architect or modification service to personalize a plan. Ask if reproducible prints or electronic CADD files are available for the selected plan. Either will make the alteration process quicker and easier.
Building a house of your own choice is the dream of many people, but when they get the opportunity and financial means to do so, they struggle to get the right house plan that would transform their dream into reality. It is a long and complicated route from the first conceptualization of a home to the house designs, floor plans, elevations, cross-sections, structural designs, and finally the completed house plan that will ultimately form the basis of the construction of the home. Most people do not have a clue as to where and how to get house designs, or even to get the right designers who can do this job for them.
Why do this, since even stock plans cost you at least a couple of hundred dollars each? Because the right stock plans can save you tons of time and money if you have a talented architect. Most plans are at least partly modular these days, and often you can even order prefabricated sections pegged to a specific house plan.
