If the perks of a single-family residence appeal to you but the price tag doesn’t, the best of both worlds is obtainable in another property type: the semi-detached house. This housing arrangement allows for efficient land use while providing separate living spaces. With noise insulation and increased privacy over townhouses, semi-detached houses strike a balance between detached homes and more affordable housing options like condos. Here are the pros and cons of this housing style, including factors such as affordability, space, maintenance and community connections.

What Is A Semi-Detached House?

A semi-detached house is a type of home that shares one common wall with another home. In other words, it’s a single-family home with a wall that joins another house. The shared wall between the two units provides structural support and serves as a boundary between them. This arrangement allows for the efficient use of land and construction materials while providing individual living spaces for each unit. The common wall helps insulate noise between the two units, providing a certain degree of privacy.

You can find semi-detached houses in many residential areas, mainly suburban neighborhoods. They offer a balance between the privacy of a detached house and the affordability and shared costs of a condominium or townhouse.

Semi-Detached Home Vs. Detached Home

Unlike detached houses, which have no shared walls, semi-detached houses are distinct living spaces that connect to the next-door home. Each unit has its own entrance, living spaces and yard. In addition, semi-detached houses are usually mirror images of each other in terms of layout and design.

On the other hand, detached homes are separate from other buildings and dwellings. Furthermore, they have distinct designs and don’t provide entrances to other homes. As a result, they have increased privacy and typically cost more than semi-detached homes.

How Much Does A Semi-Detached House Cost?

Semi-Detached House FAQs

Here are some frequently asked questions about semi-detached houses to enhance your understanding.

What’s the difference between a semi-detached home vs. a townhouse?

Semi-detached homes typically provide more square footage and a larger yard than a townhouse, even if you share the lot with your neighbor. In general, a semi-detached home is more spacious while remaining cost-effective.

Is a semi-detached home the same as a duplex?

A duplex is a building with two residential units stacked vertically or joined horizontally, while a semi-detached home consists of two houses sharing a common wall. In addition, a single owner usually rents out a duplex, but separate individuals or families can own each unit of a semi-detached home. Lastly, duplex units often share common infrastructure, fostering interdependence, whereas semi-detached homes offer more independence with separate utility connections and systems for each unit.

Where can I find semi-detached housing?

Although semi-detached housing is widespread in England, this home type is also available in the United States. As a result, you can find semi-detached housing in the same areas as traditional single-family housing, including suburbs, new developments and established urban neighborhoods.

The Bottom Line

A semi-detached house shares a wall with a connected home. However, because of its individual entrance, yard, utilities and living space, it functions like a detached family home. Plus, the shared border with another home reduces housing costs. As a result, these homes have a combination of affordability and privacy unique from townhouses and condos.
