The Ultimate Guide to Side Return Extensions

The Ultimate Guide to Side Return Extensions: Transform Your Home

A side return extension is one of the most effective ways to increase space and add value to your home. Often, the narrow strip of land at the side of a house is underutilised, but with careful planning, it can be transformed into a light-filled, modern living space.

If you’re based in West London or Buckinghamshire, a side return extension could be the perfect solution to enhance your home’s functionality and aesthetic appeal.

Why Choose a Side Return Extension?

1. Maximise Unused Space

Most homes—especially Victorian and Edwardian terraces—have a narrow side alley that serves little purpose. Extending into this area allows you to expand your kitchen or dining space without sacrificing garden space.

2. Create an Open-Plan Living Area

Side return extensions are ideal for open-plan layouts, making your home feel more spacious and connected. By incorporating large windows, skylights, or bi-fold doors, you can seamlessly blend indoor and outdoor living.

3. Increase Natural Light

Traditional homes can often feel dark and enclosed, but a side return extension introduces more daylight with:
Glass roof panels or skylights
Floor-to-ceiling windows
Sliding or bi-fold doors leading to the garden

4. Boost Your Property Value

Adding extra living space and a modern kitchen extension can increase your home’s market value by up to 20%. This makes it a smart investment if you’re planning to sell in the future.

Key Considerations Before Starting Your Side Return Extension

Planning Permission & Building Regulations

In most cases, side return extensions fall under permitted development (meaning you don’t need planning permission). However, if you live in a listed building or conservation area, you’ll need approval.

Budget & Costs

The cost of a side return extension varies based on factors such as size, materials, and finishes. On average, expect to invest between £30,000 – £60,000.

Design & Layout

Consider:

  • How will the new space integrate with your existing home?
  • What type of doors and windows will maximise light?
  • Do you want a fully open-plan kitchen or a separate dining space?
