A home is a place of residence or refuge. When it refers to a building, it is usually a place in which an individual or a family can rest and store personal property. Most modern-day households contain sanitary facilities and a means of preparing food. Animals have their own homes as well, either living in the wild or shared with humans in a domesticated environment. "Home" is also used to refer to the geographical area (whether it be a suburb, town, city or country) in which a person grew up or feels they belong, or it can refer to the native habitat of a wild animal. Sometimes, as an alternative to the definition of "home" as a physical locale ("Home is where you hang your hat"), home may be perceived to have no physical location—instead, home may relate instead to a mental or emotional state of refuge or comfort. Popular sayings along these lines are "Home is where the heart is" or "You can never go home again". There are cultures in which members lack permanent homes, such as with nomadic people.
Modular buildings and modular homes are sectional prefabricated buildings or houses that consist of multiple modules or sections which are built in a remote facility and then delivered to their intended site of use. The modules are assembled into a single residential building using either a crane or trucks.
Modular buildings are considerably different from mobile homes or manufactured homes. Off-frame modular dwellings differ from mobile homes largely in their absence of axles or a frame, meaning that they are typically transported to their site by means of flat-bed trucks; however, some modular dwellings are built on a steel frame (on-frame modular) that can be used for transportation to the site. Many modular homes have multiple levels. Homes are often set in place using a crane.
