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.
Octagon houses were a unique house style briefly popular in the 1850s in the United States and Canada. They are characterised by an octagonal (eight-sided) plan, and often feature a flat roof and a veranda all round. Their unusual shape and appearance, quite different from the ornate pitched-roof houses typical of the period, can generally be traced to the influence of one man, amateur architect and lifestyle pundit Orson Squire Fowler. Although there are other octagonal houses worldwide, the term octagon house usually refers specifically to octagonal houses built in North America during this period, and up to the early 1900s.
