As a result, you'll find one-level home plans (i.e., one level and that's it) as well as one-level floor plans with a basement in this collection of single-story house designs (because a basement lives below ground). Basements are a popular addition to houses, especially here in the United States. If you want to be sure that any given house plan can accommodate a basement, look for evidence of stairs going down into a lower level or area. The presence of these stairs will usually indicate that the house has a basement. Some people choose to have a basement built specifically for storage. This may not be possible on all house plans but if it is, the architect who designed the house plan should be able to tell you what type of construction was used in order to determine whether a basement could be built. The size of your basement will depend on how much stuff you want to store down there! Most basements are between 8 feet and 10 feet deep. Smaller basements are easier to maintain while larger ones have more room to work with. You can store just about anything in a basement including: toys and games, clothes, tools, books, manuscripts, and even an automobile! The only thing you cannot store in a basement is water.
