Rear extensions can come in two main forms: single and multi-storey. The difference is the number of floors that are created. Illustrated here you can see the additional space and size generated by this type of extension compared to the original property. A rear extension will extend beyond the original home, most commonly into the rear garden and form a part of the existing house by way of a structural opening/s to make the addition seamless internally. These extensions are typical when a side extension or side return is not possible and the extension must then follow the boundaries of the garden and available space.
These additions give you the advantage of added space, normally forming a part of a kitchen and living space, depending on your design choices. A multi-storey extension provides an even greater capacity for adding additional bedrooms and bathrooms to the existing property providing double space.
Much like a rear extension, a side extension represents all of the same characteristics. It can be a single or multi-storey and is often chosen to utilize the space that the home owner has available externally. A side extension will extend beyond the original home, most commonly into the rear garden, on its side and form part of the existing house by way of a structural opening/s to make the addition seamless internally. These extensions typically involve more work as larger structural openings are created to blend the old and new structures together. The increased width as to the dynamic or design of the finished space so it’s worth considering the completed look if you have a choice of a rear or side… if not both.
In London, Victorian houses often have an L-shaped form, looking like an addition. In an adjoined, our terrace configuration creates a natural rectangular alley space between these homes allowing for a side extension, or what’s know as an ‘infill extension’, to be created.
A wrap around or side return extension is essentially a combination of a rear and side extension. Once again it can be formed into a single or multi-storey structure, but most commonly they are single storey. They are popular in the capital, especially as they utilize the alley space, created in many Victorian properties, and thus create a very large kitchen/dining and living space without encroaching as much on the garden space. The additional roof space encourages the use of more windows, which, compared to other extensions, generates more natural light into the finished space.
