Single storey extensions are amongst the most popular of ways to add extra space and value to a house – and it really isn't hard to see why. Unlike two-storey extensions, single storey designs often won't require planning permission, plus they can totally transform an existing layout, allowing you to use your home in ways you hadn't perhaps previously considered, as well as enhancing the external appearance of your property.

Here, we take you through everything that is involved with building an extension like this, from how much to budget, to the ways in which professional designers can help develop your extension ideas.
