What Is a Semi-Detached House? A Complete Guide for UK Homebuyers

If you’re entering the UK housing market, one common question you might have is what is a semi detached house? This type of property is a popular option for many homebuyers, blending privacy, affordability, and space. As an SEO expert, I’ll provide a comprehensive guide answering all your questions about semi-detached properties, including different terms like “duplex,” “linked semi detached house,” and how they compare with other home types.

What Is a Semi Detached House?

In simple terms, a semi detached house is a pair of houses joined together by a shared wall. Each property usually has its own separate entrance, garden, and driveway. It’s like having one neighbour directly attached but with your own self-contained home. This term frequently comes up when discussing UK homes and offers a good middle ground between flats and fully detached houses.

What Is a Semi Detached House in UK?

In the UK, a semi detached house is typically a two-family dwelling where two houses share a common wall. This design originated in the early 20th century to provide affordable but roomy housing for working families. Many suburban areas showcase rows of semi detached homes with similar architectural styles and modest front and back gardens.

These homes are prized for:

• Offering more privacy than terraces
• Usually having a driveway and private garden
• Being more affordable than detached houses

The charm of a semi detached house appeals to families who want space and independence but don’t want the full price of a detached property.

What Is a Semi Detached House Mean?

Sometimes people ask, “what does semi detached house mean?” It simply means a house sharing a common wall with only one adjacent house (unlike terraces, which have neighbours on both sides). Semi detached homes often come with:

• One shared wall
• Two separate front and back gardens
• Separate outdoor parking

Unlike terraced or linked houses, semi detached homes have only one neighbour attached on one side.

What Is a Semi Detached Row House?

A semi detached row house refers to houses that are linked in a line but only in pairs—so technically, each semi detached house is one half of a row of two. This term is less commonly used in the UK but is occasionally used in markets influenced by American property terms.

To clarify:

• A row house (terrace) is a series of homes connected side by side.
• A semi detached row house is essentially the pair that makes up one semi detached building.

What Is a Duplex Semi Detached House?

The term duplex semi detached house can confuse some buyers. A duplex generally means a property divided into two separate homes, either side-by-side or stacked vertically (like two floors). A duplex semi detached house would be:

• Two homes rigidly connected side by side sharing one wall
• Each home possibly having multiple floors but separate entrances

In practice, the term “duplex” is less used in the UK than in North America but means essentially the same as semi detached when the two homes share one wall.

What Is a Semi Detached House vs Duplex?

Differences between a semi detached house and a duplex mostly come down to geography and terminology:

Feature	Semi Detached House (UK)	Duplex (North America)
Shared Wall	Usually one wall shared	Side-by-side or stacked units
Entrance	Separate entrances	Separate or shared, varies
Ownership	Individual ownership per home	Often individual ownership
Usage	Typically a single-family home	Can be single-family or rental

In the UK, what Americans call a duplex is often just a semi detached house.

What Is a Detached or Semi Detached House?

When buyers ask about what is a detached or semi detached house, they are comparing two major types of UK homes:

• Detached house: A completely standalone building with no shared walls.
• Semi detached house: Shares exactly one wall with another home.

Detached homes offer maximum privacy and space but come at a premium price. Semi detached homes balance privacy, affordability, and community feel. Choices depend on budget, lifestyle needs, and location.

What Is a Linked Semi Detached House?

A linked semi detached house is a variation on the classic semi detached model where the properties are joined not just by a wall but sometimes by an underground garage or connecting corridor. You get the benefit of a shared structure without the typical side-by-side wall arrangement.

This type is rarer but can be found in some modern developments aiming to combine the privacy of detached homes with the cost-saving structure of semi detached ones.

Why Choose a Semi Detached House?

Prospective buyers prefer semi detached homes for many reasons:

• Cost-effective compared to detached houses but more private than terraces
• Often larger gardens and parking spaces
• Quiet neighbourhood feel but still part of a community
• Better sound insulation than terraced houses
