1-Structure

Structure
The developed world in general features three basic types of house that have their own ground-level entry and private open space, and usually on a separately titled parcel of land:
Single-family detached houses - free-standing on all sides.
Semi-detached houses - houses that are attached, usually to only one other house via a
party wall.
Terraced house (UK) or row house (also known as a townhouse) (USA) - attached to other houses, possibly in a row, each separated by a party wall
.
In addition, there are various forms of attached housing where a number of dwelling units are co-located within the same structure, which share a ground-level entry and may or may not have any private open space, such as apartments or flats of various scales. Another type of housing is moveable, such as houseboats, caravans, and trailer homes.
In the United Kingdom, 27% of the population lived in terraced houses and 32% in semi-detached houses, as of 2002. In the United States in 2000, 61.4% of people lived in detached houses and 5.6% in semi-detached houses, 26% in row houses or apartments, and 7% in mobile homes.
People build "face houses" in one or more faces; though they occur most commonly as a fort or playhouse for a child, this design sometimes serves as a house for adults.
