Rear vs. Side Home Extensions: What’s Best for Your London Property?

Thinking about expanding your home in London? An extension can add valuable space, boost property value, and improve how you live. But choosing between a rear extension or a side return extension can be tricky. Here’s what you need to know to make the right decision for your property.

What Is a Rear Extension?

A rear extension is built out from the back of your house — often into the garden area. It’s ideal for creating large open-plan kitchens, dining rooms, or living areas.

Pros:

  • Can significantly increase floor space
  • Works well with open-plan layouts
  • Often suitable for ground-floor flats or terraced homes

Considerations:

  • May reduce garden size
  • Planning permission might be required depending on size

What Is a Side Return Extension?

A side return extension fills in the narrow alley or unused space at the side of your house — usually found in Victorian and Edwardian terraced homes.

Pros:

  • Maximises “dead” space on the side of the property
  • Maintains most of the garden
  • Great for letting in natural light with skylights or glazing

Considerations:

  • Typically narrower than rear extensions
  • Structural changes to supporting walls may be needed

Which One Is Right for You?

The best option depends on:

  • Your property layout
  • Available outdoor space
  • Budget
  • Planning restrictions
  • Your lifestyle and what the new space will be used for

Sometimes, a combination of both — a wraparound extension — can provide the ultimate space upgrade.
