A side extension extends from the side of the property.



A rear extension extends from the back of the property and usually out onto the garden. They are usually built on houses where there is no option for a side, side return or wrap-around extension.



Side return extensions are located at the side return void found on virtually every Victorian and Edwardian property.  transforming the section of unused garden space into a truly contemporary living space.


This extension is a side return extension which is combined with a rear extension to make an L-shaped space that wraps around your home. These are ideal if you really want to maximise the space to your property.
