A townhouse, or terraced house, originated in 16th century Europe. It is a row of mirror-image homes which share a common wall on one side. Townhouses are separate residences constructed side-by-side. They are often built on small lot areas and designed with multiple floors. Each townhouse is occupied by one family. The family has ownership of the land where their townhouse is built on. In the past, aristocrats used townhouses as their city dwelling place where balls and charities would take place. Currently, townhouses are sprouting like mushrooms in the city due to the scarcity of space. An advantage of townhouse living is that they are often built in convenient locations. The property is also easy to maintain. Moreover, it is less challenging to get to know your neighbors.

A duplex at first glance would seem to be the usual single-detached house. But it is basically a building or house which has 2 separate units. The units share a common overall structure but have separate entrances as well as separate living areas, kitchens, bathrooms, and bedrooms. A duplex is commonly 2 stories high like the average home. It is usually occupied by two families. Typically, one family owns the property and the other unit is rented out to another family. In some countries, a duplex is also called a “two-flat” or “two-family dwelling.”
