    A rear extension is where the only rear end of the property is being extended.

    A lot of terraced and semi-detached houses that define so much urban landscape, especially within London districts, are ripe for these house additions. Mostly, side return extensions are relatively small extensions, but they will definitely give a great impact on the look and feel of your property. Sometimes, a side return extension can be combined with a rear extension which is called a wrap-around extension. A side return extension is a truly great option for creating open-plan kitchen and dining areas.


    Viewing property from the outside, it may appear you will only gain a few extra meters inside, but a large structural opening will make a major difference to the internal layout and creates a new spacious feeling to your house. Most side return extensions do require planning permission and only a few can be built under permitted development rules.

    The wrap-around extension will give maximum space and significantly improve the feeling and view of your home. If you want to achieve an open plan kitchen with large dining or living areas to your house, then a wrap-around extension is the perfect option for you. Depending on the width of the plot, a wrap-around extension provides one of the most favorable opportunities in terms of home improvements and will create a fantastic connection between indoor living zones and the garden. This will be achieved by fitting Sliding/Bi-folding doors systems and adding huge roof windows or even creating a full glass roof to let plenty of natural light.

    A number of planning rules need to be dealt with designing wrap-around extensions and structurally it’s a more complicated build than side return extension. On some occasions, you do need to require planning permission, and only a few fall under permitted development guidelines.

    A double-storey house extension can be just what you need, to transform your home into a bigger, more welcoming space for you and your family. Whether you just want to increase the living space in an existing room or add a whole new room altogether, a double-storey extension is an ideal way to ensure that you get much more space out of your old house, even if it looks like you’ve grown out of it.

    Additionally, a double-storey extension can prove to be an even more cost-effective solution than single-storey extensions, as the extension itself can spread the cost of the foundations and the roof, and as a result, the average construction cost per square metre is lowered. In many cases, double-storey extensions don’t require planning permission, e.g. when the extension isn’t taller than the highest part of your roof. Make sure you do the proper research before deciding on this form of extension.
