Types of Home Extensions

When it comes to extending your London or Hertfordshire home, there are many options from which to choose. And, thanks to the permitted development rights, which has recently been extended by the government, you might not need to apply for planning permission if you fit within certain guidelines. Below we have outlined the various types of house extensions available, to give you an idea of what's involved, the costs, and how they’ll transform your home. 

Single Storey House Extension

Single storey extensions have been gaining popularity amongst homeowners in London, as they can visually connect the house with the garden when using sliding glass doors or panels. They come in three different types - rear extensions, side return extensions and wrap around house extensions (which are effectively a combination of both the rear and the side extensions). You could use your new space to accommodate a larger kitchen, stylish living room or even a home office.

Double Storey House Extension

A double storey extension is a cost-effective option, allowing you to double your space under the same roof (which tends to be the most expensive parts of the build). Two storey extensions are typically used to create an open plan kitchen, dining and sitting area with sliding or bi-fold glass doors allowing access to the garden on the lower half. The second half can become anything you like, such as a large family bathroom, additional bedroom, library/study or even a gym.

Over-structure Home Extension

A clever way of using an existing building, such as a previous single storey kitchen extension or an attached garage, is to create a new extension on top of it. This type of home extension project is ideal if you want to add a large en-suite bedroom or a playroom for the children to your home. It can prove one of the most expensive types of extension though in the event the existing structure has single-skin brickwork (in which case more work would be required to strengthen it).

What are the Benefits of adding a House Extension to your Home?

As well as the obvious advantages for you and your family of an extension, such as more space to co-habit in, it will also add light to the existing structure (thanks to all that glass), making it feel like a space you’ll all want to gravitate too. This can help make your home feel more communal. Financially, yes, an extension can be a lot of money to fork out, but you will undoubtedly get your money back when it comes time to sell and move on, since it will most certainly have added to the value of your home.

Are you thinking about building a house extension but haven't yet quite decided what you would use your newly gained space for? To provide you with some inspiration, we have put together a list of bespoke ideas on how to turn an ordinary room into an extraordinary living space where the whole family will love spending their free time and which all your friends will want to visit regularly.
