A townhouse, also known as a townhome or town house, is a type of housing that shares one or two walls with adjacent properties but has its own entrance. They are generally attached to other townhouses on one or both sides, sharing walls and a common roof. Townhouses are designed for high-density, urban environments, with a tall and narrow silhouette. They can be a great option for homebuyers who enjoy living close to their neighbors or who crave a compromise between a detached house and an apartment.

Some key features of townhouses include:

• Physical attachment to neighbors: Townhouses are physically attached to their neighbors, as opposed to a totally detached dwelling.
• Multiple floors: Townhouses are often multilevel homes with at least two floors.
• Ownership structure: The ownership structure of a townhouse can take several forms, including single-family homes and condos.
• Less maintenance: The smaller size of a townhouse means that it requires less maintenance, especially in terms of yard work.
• Shared amenities: Townhouses built as part of a development might include shared facilities such as a pool, gym, or clubhouse.

Its important to note that the term "townhouse" can refer to different types of housing depending on the region. For example, in the United Kingdom, the term originally referred to any type of city residence of someone whose main or largest residence was a country house. In the United States and Canada, a townhouse has two connotations. The older predates the automobile and denotes a house on a small footprint in a city, but because of its multiple floors (sometimes six or more), it has a large living space, often with servants quarters. The name townhouse or townhome was later used to describe non-uniform units in suburban areas that are designed to mimic detached or semi-detached homes. Today, the term townhouse is used to describe units mimicking a detached home that are attached in a multi-unit complex.

In summary, a townhouse is a type of housing that shares one or two walls with adjacent properties but has its own entrance. They are designed for high-density, urban environments and can be a great option for homebuyers who enjoy living close to their neighbors or who crave a compromise between a detached house and an apartment.
