What are the Different Types of House Extensions?

Christian Brailey

If you want to expand your current living space, a house extension is undoubtedly the way to go. However, if it’s your first time expanding, what options do you have when considering a design?

Below we look at the main types of house extension and what they can add to your property.

Side return extensions

If you have a passage or path down the side of your property, a side return extension could be for you. If you find your side access isn’t being in used (in some cases it can actually greatly reduce your home security), you may want to look into a side return extension. 

Although the dimensions of the extension will usually be quite small – it can help to enlarge your living space, improve home security with the bonus that planning permission is rarely required.

 What are the Different Types of House Extensions?

Rear extensions

As the name suggests, a rear extension allows you to extend onto the rear of your home, usually into the garden. They are great for creating an extended indoor living area such as a dining area or conservatory that highlights standout outdoor features such as landscaping and garden ironwork. 

A small extension also rarely requires planning permission, although they can take up to six months to plan and build. 

Wrap around extensions

Wrap around extensions are a mixture of the two types above, extending the property both to the side and rear of the property. They are ideal for creating larger open plan spaces, particularly suiting families wanting an open plan living/kitchen area. Many country residences want extra space for a new extensive modern kitchens or even more traditional designs that require additional space for features such as a reconditioned electric Aga range cooker.

Although they are larger than the first two types of extension, they still rarely require planning permission although may take longer to build.

 What are the Different Types of House Extensions?

Double storey extensions

Double storey extensions mean taking one of the above, rear, side return or wrap around shapes and extending it over two floors. 

Despite giving you the same potential increase in space, the costs will usually be around half of a single storey extension due to the lesser requirements for building foundations. Despite this, you will usually need planning permission from a local authority to get this built.

Attic/Loft (Dormer) extension

If you rarely use your attic/loft, a dormer extension could be perfect for you. A dormer extension removes some of the pitch of the roof and creates a box space well-suited to creating a study, ensuite bathroom or larger bedroom. 

They usually don’t need planning permission and are reasonably cost-effective.

Garage or other Outbuilding Extension

Extending your living space with a garage or other outbuilding such as a utility room, swimming pool or kennels is a great way to add space to the dimensions of your home.

As you are substantially adding to the footprint of your home, you will require planning permission and of course new foundations so expect costs to be relatively high.

There is also the option to add extensions onto existing garages or outbuildings, with double story garage extensions becoming more and more popular.

Feeling Cramped? It Could be Time to Extend

If you are feeling restricted in your property a home extension is undoubtedly the way to go. Before you consult with an architect on specific plans, we hope learning about the different types available gives you inspiration for what is possible with your own home.
