In which type of house is urban density usually higher due to shared wall constructions?

Urban density tends to be higher in townhouses because these residential units are designed with shared walls, which allows for more homes to be built within a smaller footprint of land. This configuration is particularly common in urban settings where land is limited and the demand for housing is high. By utilizing vertical space and constructing homes that are attached to one another, developers can maximize the number of units available in a given area.

In a townhouse setup, each unit typically shares at least one wall with an adjacent home, which minimizes the amount of land needed per household. This characteristic is a key factor in urban planning and development, as it allows for the preservation of green space and the development of higher-density living environments.

Other types of housing, such as apartments and duplexes, may also contribute to urban density, but townhouses are specifically designed to promote a higher number of residences within a compact area due to their unique construction style.
