What is a Side Return Extension?
A side return extension fills in the narrow alley that runs alongside many terrace, semi-detached, and Victorian-era homes. This often-overlooked space is typically only 1–2 metres wide but can completely transform the feel and function of your home.
When combined with a rear extension, a side return extension creates an L-shaped addition that dramatically increases floor space. The addition of a roof lantern or full-length skylight floods the new space with natural light.
Side Return Extension FAQs
How much does a side return extension cost?
Side return extensions typically cost $2,800–$4,500 per square metre. Because they often involve structural steel and rooflights, they can be slightly more per m² than a straightforward rear extension. A typical project costs $80,000–$150,000.
Do I need planning permission for a side return extension?
Side return extensions usually require council approval as they are visible from the street in most cases. We manage the entire approval process on your behalf.
