What is a semi-detached house?
Let’s start with the basics and define exactly what a semi-detached house is. Simply put: it’s a house that shares just one common wall with its neighbouring property. It may help to picture a detached house as a reference point: these have no walls shared with neighbouring homes and are standalone properties. The distinction will become more important as we dig deeper into the rules and regulations surrounding semi-detached wraparound extensions.
Can you add an extension to a semi-detached house?
The simple answer is that most of the time you can. And there are plenty of types of extension to choose from. To learn more about the different types and to explore what could suit you, read our guide to home extensions. Read on for more streamlined information regarding semi-detached wraparound extensions.
Why are wraparound extensions a good choice for semi-detached houses?
For the uninitiated: a wraparound extension combines a side extension and a rear extension to create an L-shape that’s built to create more space in your home. Given that semi detached houses tend to have unused space to one side and generally have some available garden space to the back of the property, it makes an excellent candidate for wraparound extensions.
Here are just a few of the potential benefits to choosing a wraparound extension for your home:
- Create a new room or enlarge an existing one
- Add more light into your home
- Improve the flow between your house and your garden (without sacrificing your whole garden)
