Featured Snippet: What Is the Difference Between Townhouse and Duplex?
The main difference between a townhouse and a duplex is structure.
A townhouse is a home that connects with other houses in a row and shares side walls, while a duplex is a single building divided into two separate homes, either side-by-side or one above the other.
In short, a townhouse is part of a row, whereas a duplex is one building split into two units.
What Is a Townhouse?
A townhouse is a multi-floor house that connects with other houses in a row. It shares walls on both sides with neighboring homes.
People often choose townhouses in cities because they offer more space than apartments while still saving land.
Examples of Townhouse:
- A 3-floor house connected with other houses in a housing society
- A family living in a row of similar houses with shared walls
๐ Simply put, a townhouse feels like a private home but stays connected to a row of houses.
What Is a Duplex?
A duplex is a single building that divides into two separate homes. Each unit has its own entrance, and families can live independently.
Builders often design duplex homes for two families or rental purposes.
Examples of Duplex:
- One family lives upstairs while another lives downstairs
- A homeowner rents one portion of the building
๐ In simple terms, a duplex is one building split into two homes.
