The possibility of a side extension is not exclusive to detached and semi-detached properties. Many Period Property houses have a strip of unused outdoor space running alongside the ground floor. These pathways often become redundant and can be transformed through side return extensions or infills.

Side return extensions are one of the most common modifications for Period Property terraced houses. Even a small side return extension can add valuable square footage to your home.

While it might seem that the extra space gained is minimal, a side return extension can convert a narrow galley kitchen into a spacious kitchen-diner or make an L-shaped room far more functional.

The good news is that you might not need planning permission for this type of extension, as it often falls under “permitted development” rights. However, it’s always wise to consult with a professional before starting any work. Obtaining planning permission can also provide more creative freedom in designing your extension.

In detached and semi-detached Period Property homes, a side extension can be used to create a home office, workshop, utility room, or simply to expand existing downstairs rooms. If you're interested in a side extension but concerned about losing outdoor storage space or access to the back garden from the front, consulting with an architecture firm can help. They can provide design solutions that retain a passageway from the front to the back garden, ensuring your extension meets all your needs.
